Thanks, everyone ...to answer a few questions and I'll send another pic (with blue bubblies!) which I can't seem to figure out and do on a "follow-up." My GH cut a small hole in top and bottom of basketball and then put a piece of water pipe (copper pipe) through it...to hold it steady. He then cut the ball open on the top enough to pour in the cement..he had this sitting in a 5 gal. bucket of sand. You can see the bb lines on the cement. Yes, you could just make a cement ball. It was fun and looks great with the old feed tub by it. Jeanne

Hi Mike. Actually on the 2" line from the sc I have a fernco fitting with a 45 elbow and other piece of pipe to centre of sc so that the out draws low enough down in the chamber. On this pipe I have a basket strainer fitting with a 16" piece of plexiglass glued over the fitting--looks like Aquaart's anit-vortex device. I did this as last year I did have a whirlpool going into the fitting before it went out into the pump. No air bubbles under the plexiglass as can see the basket fitting. The basket is threaded onto the pipe but I did not use any teflon tape. If I switch this pump out into the higher head waterfall (has about 4 ft of head) I don't get as many bubbles in the priming pot. Tried this pump on the sc line to pump to smaller waterfall which is a 50 gal drum buried in the ground full of springflo. From the ball valve on the outside of the pump there is 18ft of 2" pipe to a 45 elbow another 7 ft of pipe to 90 elbow and intake 12" up from the bottom of the barrel. Ground level to top of barrel is the barrel height--maybe 3ft??. I call it the smaller waterfall as it's not as high. I thought I should have the main mechanical (sc with matala mats) running to the this biofalls as the higher one is one of those little giant filter falls and doesn't have as much media in it. I am waiting for the priming pot for my old Sequence 750 pump (the one with the bent shaft) and was planning on running it on the skimmer line. When I sent this pump to Canadiankoi...and they tested it they said it was pumping at about 3600 gph instead of the 4200gph should be pumping. This rate would probably be better for the main biomedia right? I am wondering if the oring is not greased properly. Lost my tube of oring grease and the local hardware store sold me plumber's grease. Maybe it's not sealing the lid properly??? Thank you so much for your help! Was 30C on Tuesday here-about 25 yesterday and raining today! Risk of frost tomorrow night and temps around 8C on Saturday. Had no algae until I started up the pump and noticed today pond is slightly green! Hot temps on Tuesday probably did that! I have very little plant cover yet as water lilies are just starting to take off and the few parrot feather and hyacinth I could afford need about 50 more! Not in my budget this year!

3/4" electrical conduit Eh!!! We'll be checking into that miss use of electrical materials. " The Lectric Specter"

Hope someone can help! Our 5yr old carp, Colin has had a white spot on his head (actually between his head & his mouth) for the last coupe of weeks. Doesn't seem to cause him any problems, but it is slightly larger & today he didn't feed (MOST UNLIKE HIM!) & seems lethargic. We had a problem with our pond in spring - the UV wasn't working properly & we lost a few shubunkins (ulcers & one had what looked like a rotting mouth - the flesh was being eaten away - poor thing) Water now seems fine (although haven't got a test - must do that tomorrow. All the other smaller fish seem healthy - but please help, cos Colin is so special, he's lovely! We did replace the water some time ago & used malachite green, which seemed to help conditions, but perhaps we need to use it again or is it something else? I'm a bit confused as to how to treat whatever it is. Help!! Thanks
