Oh, I like that idea. Except for the part about the string going through the water and up to the dock. Knowing my fish, one of them would swim into it and knock off a scale, ending a show career. I think I'd rather tie the end of the string to something that can sit in the bottom of the pond next to the drain cover. Like a piece of PCV pipe or a large stainless steel nut. Anything that won't slip under the bottom drain dome. A large nut might be ideal, because I could hook it with something and pull the string up without even getting in the pond. I had to go swimming yesterday to unclog drains. I knew they were starting to run slow and needed cleaning, but of course while I was away for the weekend my poor DH had to try to keep the filters going with the suddenly even more reduced flow. I wish I had thought to run a string through the actual drain lines and clean them while I was already wet. I am sure the drain lines have a lot of icky stuff on the walls after 5 years in service.

Susan I think chemicals are bad for your pond and I have been ponding for many years. I don't know what Microbe Life or GreenClean contain so I am not sure if they are harmful. But the best way to keep a pond healthy and happy is to keep if free from debris that settles on the bottom, filter the water and make sure it has lots of oxygen. If you don't want to add filtration the concentrate on debris removal and water changes. There are so many ways to filter your pond. Many people vacuum the pond bottom, some use retro-fit bottom drains to keep the bottom clean and those who are newly installing a pond will include a bottom drain to their ponds. Filtering the pond is important to keep maintenance at a minimun. You need to remove as much debris as possible with a good filter and make sure you have biological filtration as well. For example I have two circuits of filtration. My skimmer has a 57 watt UV light and all the water that is drawn from the surface goes to a big DIY filter that uses foam, plants and Savio springflow to help with the mechanical filtation and the biofiltration. My bottom drain goes to a settling pond in which the debris settles to the another small pond and it is cleaned out a few times a year. Since your pond is concrete then a retro-fit bottom drain could help. But vacuuming would work as well. When I first started out ponding I would vacuum my pond with a pump that I held with a small rope. I used that and a net to get out debis. Very low tech but worked well. I would then add fresh water to replace what I had taken out. Years go by and I have experimented with underground filters, Bead filters and DIY filters. When I rebuilt the pond (a few times I admit) the bottom drain attached to a seperate pond made maintenance much easier. So you just need to find the type of filtration that suits your needs. At the very least keep the bottom clean and do some water changes during the season. This is a very simple way to keep your pond healthy. Also the catfish will not hurt your fish. When I had my catfish he co-exsisted very well with the Koi. RIP Wayne. Lisa

Nothing in the pond has been touched since it was finished in October. The water is actually clear as a bell, just slighly discolored, probably reflecting the algae on the bottom. Water test kit shows everything is fine. The UV light is on, and I have an extra bulb and know how to replace it. As for the camera, it is from National Geographic - they make a film version and a digital version. I use the digital. The name of it is "Wildview" and I got it on the National Geographic Web Site. It can be set for 1, 5, 10, and 20 minute timeouts, and for high and low resolution. It comes with a strap for securing it to a tree. All you need to do is attach it to the computer with a USB cable and upload the photos. If you have a PC with Windows 98 or earlier, you need the software which comes with it.

will the sand affect my pond life? Yes, but probably not a lot. Certain kinds of life, animal and plant, will make the sand home if they make it to your pond. What plant life should I add to feed my fish and welcome in other wildlife like frogs and dragonflies? That really depends on the person. I like to add any plant I can and see how it does. It stays if I like it. That's how I learn. So for me I'd try any plant, and I'd try it different ways...in water, in soil, in sun, in shade, etc., to learn how it grows. Duckweed is a plant fish will eat directly, but after they've eaten it all it's gone. So if you want an on going duckweed food source you have to protect some or easier imo is growing it in a separate shallow pond. But a more important food source is all the life in a pond, mainly insects. They eat the plants and the fish eat the insects. So all plants really feed fish indirectly. Dead, rotting plant material feeds insects the best. But many people don't like that in their pond...so it's really best to decide what kind of pond you want...Wildlife Pond, Water Garden or Koi Pond. That determines how plants are used. You can try one and if you don't like it you can change to another pretty easy or some pond in between. the water looks a little murky. (BONUS QUESTION) Is there any way to clean that up? It's pretty simple to clear up water but only after you know what's causing it to be murky which is the complex part. There are lots of filters and methods to removing different things so the filter has to be matched to the stuff being removed. One pretty universal murky clear is a 24/7 drip water change system. A drip emitter runs 24/7 into the pond and an overflow takes away the extra water. I plan on heading over to a local park nearby and yanking out a couple of cattails and whatever else I find interesting, I highly doubt it's illegal and the poor little stream that leads to the enormous carp pond is choking with all the vegetation. (OH! I know that these plants will probably have other bacteria and algae and critters on or in it, is there any way to clean them without killing them? There are chemical baths you can use, including chlorine and similar oxidizers. They aren't super effective imo. The question is do you want to do that or are all these critters something you want? You see this goes back to deciding what kind of pond you want. A Koi Pond owner with thousands of dollars worth of koi would never allow any plant within 10' of their pond. Their focus is koi and the risk of pathogen form plant would be unacceptable. At the other end of the pond spectrum a Wildlife Pond owner would welcome all those "pathogens". It's a matter of perspective. To these pond keepers "pathogen" is just another name for "life". That's what natural ponds are, life. Stuff killing and eating other stuff. I want to make sure the plants are settled before getting fish, but I heard that a certain string? Algae is a pain to get rid of, does that grow in zone 9?) You don't get rid of algae, you control it. Just like you weed a garden. Algae grows in all zones, from the poles to the equator. There are thousands of species. ...since I live in zone 9 in one of the cities that borders the Rio Grande, Does anyone have any recommendations for the type of plants I might want to scavenge for, how to transport and transplant them from the stream into my pond, and what no-no plants I should try to avoid? Giant Reed, Arundo donax, is a spectacular plant you can probably find. It's an aggressive grower, makes bamboo look like Pussy Willow. I don't believe there is such a thing as a no-no plant. They're plants, you're a human. I have to assume you can win any battle. Ponds are just like any garden. If you tend it you win. If you go away and come back in a year the plants win. (If I find any I kind of want some duckweed... is this a no-no plant? Will keeping the growth at bay turn into an overwhelming hassle for my medium-small sized pond?) Depends on how much hassle you consider keeping a pond is. For me it's a joy. And whether your fish.eat it. I want goldfish!! I hear commits are really friendly, but what other species can I add? Can someone supply a list? Oh, and how many can I add? (I was thinking about 6-8 fish total) Common, Comets, Shubunkin, Wakin. The fancy kinds can look a little out of place. I've had some of these because friends need to get rid of "pets" sometimes. They look a little odd to me when mixed with other kinds. Like when you feed them the others swim over fast and the Fantail seems to struggle to swim 10'. But the fancy ones seemed to do fine but need exact protection from streams, skimmers, etc., as they're not strong swimmers.. The Common, Comets and Shubunkin are also often crossed. Like a Comets and Shubunkin to get a Shubunkin with a long tail. Commons get the biggest, more than 12" and over 3' sometimes although these may be koi crosses. (Even numbers so they can have a buddy system, but not like Nohas ark, they can only be friends!! No babies!!... okay maybe a few so I can add them to future smaller water features around the garden...) You can post a sign explaining breeding rules but goldfish are either not very good readers or not very good rule followers (even worst than teenagers). which leads me to the after thought question... Can different species of goldfish mate? I mean.. they are still goldfish... Yes. When different kinds of goldfish breed the result is considered a goldfish too. Goldfish can also breed with koi. I know that bottom feeders won't eat all the gunk that will eventually fill the bottom, (I can't blame them) But are there any fish that I can add that will eat the bottom pellets? (Like catfish maybe, or something cooler/cuter) Pellets, as in sinking food pellets? Goldfish, koi, catfish, pretty much any fish will eat food on the bottom. There are terms like "bottom feeder" but that's just a general type thing. Like catfish will spend most of their time on the bottom but will eat food on the surface just like a goldfish or koi. And they will come a running when they see you just like goldfish and koi. As for gunk...bacteria lives there, bugs too which eat the bacteria, bigger bugs that eat the smaller bugs and fish root around in there looking for bugs to eat. It's a whole cycle thing. Gunk on the pond bottom is basically soil, or stuff on it's way to becoming soil. Nothing removes it completely, just like nothing removes soil completely. Stuff lives in it, eats some growing in it, breaks it down into better and better soil (from a plant's perspective). Oh, and is Walmart a smart place to buy these babies at? (I'm sure most are familiar with the store...) My only other option is PetCo... Are they a good option? I don't want to buy bad fish... but I would feel terrible if I had to take a fish back because it was sick or it got the others sick... There not really anything like a "good" store to by goldfish. Here's how it wroks. The store orders fish from a grower. The grower has a bunch of ponds with different kinds of fish. The grower puts a bunch of fish into a box and sends it to the store. The store dumps the box of fish into a big tank. An employee gets a net and scoops out a few of the the prettier fish and puts these into separate tanks. Like for instance some Shubunkins would go into a tank labeled "Shubunkin $4.95". And some orange and white Comets will often be labeled "Sarasa $4.95" even though they aren't actually Sarasa. The rest in the big tank are labeled "Feeder Goldfish 20 for $1". When customers buy $4.95 fishes the clerks grab a net and scoop a few more nicer looking fish out of the feeder tank and into the $4.95 tanks. People just assume when they see 10 fish in a nice aquarium at eye level that they must be higher quality and healthier fish than the horrible feeder fish tank. It's just marketing and logistics. You can often find very nice looking Shubunkins and Comets in the feeder tank. It just depends on what they get in. Growers don't care since it's just as easy to grow Commons or Comets or Shubunkins. They'll send whatever they have. The fancy goldfish may be shipped in separate containers. This is not to say all fish are healthy. In my experience 50% of feeder fish died in the first 24 hours. And in most stores they also don't last long either. Yes, you can quarantine them, you can treat them for parasites, etc. Depends on the kind of pond you want to keep. Most ponds I've had I only used feeder goldfish. Set up a quarantine tank and buy $10 worth of meds to treat $1 worth of fish...not me. I just put them into the pond and hope for the best. But that's me. I do want to hand feed my fish. I know the risks of them getting hurt by other animals but I have 3 small dogs that scare away all cats and wild animals, but are really just yapping balls of harmless fur. Pretty much all kinds of fish can be trained to be hand fed. Takes them a few times to get the idea but once they do they're trained. The 3 small dogs...I hate to impugn the K9 reputation for diligence but all that yapping..yeah, that's mostly for your benefit. When you're not around and the Herons are having brunch the dogs are really unlikely to do more than blink at the carnage. The Herons aren't hurting anything...it's not like they're doing something horrible like squeezing a squeaky toy. They're just eating all of your fish. Big woop. Now if the dogs happen to hear you at the front door then sure, they'll be off like a rocket to tear that Heron a new beak, jumping through plate glass windows, busting down doors, whatever it takes to impress you and keep those treats flowing.
