Successful test run yesterday.
As predicted, it was very difficult to get the top to seal. I really had to dog it down tight with a wrench. That's going to make recharging it very inconvenient. I thought thumbscrews were bad.
Other design issue is that because the wear pad does not cover the...
Anyone have a feel for what the low-end temperature range is for coral?
I am entering my first winter season with my system, which has the sump in an unheated garage. So far I've been able to keep it above 75F, but I fear heroic measures may be needed when it gets really cold.
I've got 650...
I got some connectors at HD that are threaded on one side and RO Tubing push-ins on the other. Then I drilled and tapped the holes into the square part of the plug and threaded them in with teflon tape.
Alternatively, I could have just drilled holes and stuck RO tubing through them, and sealed...
Thanks, I'll give it a try. I just bought a heat gun for bending plexi, that should work. Didn't know about the sand.
I added a 3" circle of plexi glued to the bottom of the chamber with a bit of silicone. It's smaller than the tube so I can (hopefully) pry it off when/if it needs replacing. As...
I can do that. Thanks!
My plan calls for the solenoids and pump to be up on top of my water tower anyway, so there's going to be no pressure-y pressure, ie, all pressure should be relleved by the output hole. But, like all walruses, I like a tight seal, and I don't want fresh, tasty kalkwasser...
You don't think it will seal tight enough? Why? I was going to use teflon tape on it. I've seen those caps used at the bottom of lo-o-o-o-o-ng pipes in sprinker systems.
The top is going to be glued just with silicone so I can more easily adjust or modify it, so it's not really a high pressure...
The Stirrer:
Dry fit with the bottom flange and tube:
The whole deal, before adding the support rod and upper flange:
I'm experimenting with some kind of wear pad so the stir bar doesn't eventually wear though the bottom of the flange. This poly cutting sheet was OK but floated to the top...
Back when we had the little kalk reactor group buy, I decided to make my own and just buy the valve and the aqualifter, so here goes. As might be expected, costs quickly get out of control, but so far so good! Parts:
Magnetic Stirrer, EBay, $65, the kind that holds a lab support rod in the back...
It really helped. When I got the skimmer the output was a long piece of PVC hose. The way I had it positioned, it was blasting water right against the first baffle in my bubble trap. It was basically forcing the micro bubble-laden water through the trap. Now I have it terminated with a shorter...
