Let me talk about what I meant before I start to answer the questions you asked. At 800 gallons you have a lot of weight in the tank roughly 7,000 lbs. There is fairly little force pushing on the bottom, about 1.5 psi so the ground will not have a problem with that force. But the wood walls will have a lot force against them. You say you are going to use cedar garden post but you don't say how it will be built. So let me tell you how mine is built. I used treated 4x4's for the walls. These were put together like Lincoln logs. On the bottom layer the corners are lap joints so there is a 4x4 going all the way around. Then there is a 4x4 on top of this on the 12' length and then a 4x4 on the 4' width so there is a 3.5" gap between each layer of 4x4 all the way up to the top where the top layer has lap joints. In each corner there is a .5" threaded rod going down through each 4x4 to hold all the 4x4's together. There is also two more .5" threaded rod on each of the long sides holding those together. Then there is 1/2" plywood lining the box with a liner inside that. Within two days after filling the tank the bottom of the long sides had bowed out at least 2 inches in the center. After about a year the long walls on the bottom had bowed about 4 to 5 inches. At that time I decided to put two 2" pipes set in concrete on each of the long sides. This stopped from bowing any more. But even with this there are some pretty good size cracks in the 4x4's after 16 years and at some point the 4x4's will fail. Why 4000 gph flow rate? This gives me a twenty minute dwell time. Is this idea? No one knows for sure but this rate has been used for years with a great deal of success. Filters today are going to a much lower dwell time and they work somewhat. My pond system is 19,500 gallons including the water in the filters. The first 12 years that I ran this filter it had 2 ft of lava rock held above the pipes on the bottom that had holes in them to distribute the water. On top this there was one roll of spring flow and 36,000 ft of 1/2" wide PVC plastic strapping. Then there was 4 inches of polyester pads. This filter was cleaned once during that time. At that point in time I removed the lava rock and replaced it with PVC ribbon which is a machined product of 1/8" wide continuous ribbon. This filter currently has about 18,000 sq ft of surface area to grow bacteria. No I do not spike the biofilter with beneficial bacteria as there is no need to do this. Currently there is no manufacture producing a beneficial bacteria with a bacteria that a good koi pond can't produce on it's own and maintain on its own. Granted it takes the pond years to do this. I have gone on here way too much all ready to continue to talk about beneficial bacteria. Depending on the type of pond beneficial bacteria is not only a good thing but a necessary thing. Mike

My skimmer is totally different. So don't know if what I do would work for you. I know it works for me, but there will be bunches of people here on the forum that will disagree. I removed the door and in the slot where the door would go I put a piece of the black (coarsest) Matala mat Then I have 3 baskets that hold filter mats and then the pump is in the rear. My skimmer pulls anything that is floating in the pond and it catches in the Matala Mat, I just take it out and hose it off. I also take the baskets out with the other filter media and hose them off at least once a week sometimes more if I need to. With all the gunk I wash out of the mats, it has to be working. Then after the water goes through all this media it goes to the waterfall. I was having a problem with fish getting in the skimmer. And I actually cut a hole in the top of the skimmer so the frogs can get in there. A frog could never go through my pump and go through to the waterfall. My pump has a filter on it and nothing gets through there unless it is miniscule.And when I remove the baskets of filter media to wash it, I can see the bottom of the skimmer and if there was anything in there I could see it.

So, today i got started on the large Craftsman garden tractor. I thought it was a twin Koehler, but its only one cylinder. But--i found one of the ignition coils not bolted down, just laying there. got that fixed. Air filter real dirty. I'll get a new one tomorrow. The owner had installed a very large fuel filter on it, and that didn't work so i put a smaller red one on it, and it starts good now. I drove it all around, even mowed a little, but then found the brakes don't work, the hard way--i ran it up a hilly bank to stop. I'll fix it, just takes some work. Owner hasn't learned the facts: You can't let them sit outside in the rain, you shouldn't allow anybody else to use it, those machines aren't a side-show machine, and a whole bunch of other truisms!

I am beyond disappointed with my LG 3700 front load wash nachine as well as the customer service through LG Canada. My machine is a year and a half old and I have been having problems since weeks into using it. I have found this post and thread very interesting. I have had various technicians from LG come to my home and have followed their recommendations as best I could with no success. I have small to large leaks of water on my floor. Not on every load so they say it can't be a leak problem. Now I am wondering about the drain filter. We do empty it regularly. There has been little to no debris on the filter. The amount of water from the drain hose ranges from around two and a half cups to several cups. Does anyone know the holding water capacity of the drain filter? It is a very long ongoing story. It has been a very exhausting and frustrating time with my "fancy" LG and their LG customer service. If you know the drain filter amount of water it can hold or any other ideas please let me . Thank you so much.
