To me, you will forever be known as the man who combined a W/D filter and a BAR....!!!!!!!

Thanks, seemed logical to me, multipurpose and does not look too bad either. Kate and I have discussed rebuilding it larger in the shape of an L.
The LFS had got in about 500 baby koi on Thursday so I stopped by and picked out a few on friday, then came home found the pond water was about 2" low. Since then I have been feeling some of Yanbbrox's plumbing pain. I found the leak was from the back of the SC and thought it was the buried uniseal connecting it to the next barrel. It had troubled me initially since the poly tank wall was so thin and people said not to use uniseals on one. So I spent the evening digging down 3 feet in mud through a 4" wide area between tanks hanging upside down. After much cursing finally today I found the leak was not the uniseal, but the 3" bulkhead drain. The uniseal allowed flex as the ground moved this spring, but the rigid bulkhead did not. Hindsight.... Anyway I finally got it dried out tonight and applied a thick bead of sealant. Will put on another layer tomorrow and fill on Monday. Hopefully it does the trick. I am leaving week after next so if it I don't get it fixed I will have to shut off the bottom drain until I get back. I still have two barrels and the wet/dry running which should suffice.
On the plus side I have a detailed plan for the next pond which will be started at the end of the month. It is going to be a simple 4x8 and raised beach for the turtles plumbed back through a bd into the main pond filtration.

Digging down, these barrels were buried to near the top for support.
I replaced the 2" drain with a 3" line for faster dumping....Use a sump pump instead anyways to get the water farther away, so kinda pointless. I may turn it into an input from the next pond. The drain line shifted when the ground softened up cracking the seal. Would not have been a problem if I had used a flexible uniseal instead.
Drained and drying
Odd feeling climbing into your filter for maintence
Goldfish starting to look for food
New baby Koi. picked up 7 butterfly and 2 standard. When I saw the pond leak I dumped them into a holding net in my 125 tank south american tank, when I returned they ahd all escaped. I caught 8, think the other may have became dinner. Hopefully he is just hiding though. I am going to keep them in my class tank until at least june to grow a little bigger.
Finally Thursday was a stressful day as chaos had her second litter. They are a handful, but are the chief fincianceers of my projects.
