Well, we have started to build our filter and and just need to test to make sure the seals hold before we install it. It is a 50 gallon stock tank that will be a skippy filter in our waterfall. Can't wait to see it in action (and the clear water). Also, got a wet/dry shop vac (9 gallon) from Home Depot yesterday so now I can suck the junk out of the bottom of the pond. It was on sale for $20!
