Budget doesn't exist in this hobby: Brian's 45g Build

Looks good Brian, your workmanship is very tidy and well thought out.

Is there enough volume in your sump if return pump is turned off ? Watch out for back flow from returns !

[The Guy]

A small hole drilled at the water line on the back side of the return pipe also works well to break the syphon in the event of the return pump going off or a power loss, on page seven I think I see a check valve in the return piping which is a good idea too, make sure to keep it clean as those pesky little snails can cause it to stay open sometimes.

Did a quick test
In my leak test the pump chamber was way overfilled so it won't normally be that full
Here's how high the water gets when the pump is off. It doesn't even fill up to my 1st chamber even when overfilled so I think I'm in the clear

Ya I don't trust these things completely. I've been trying to find the check valve for the loc lines as a second measure but it's either not available or ridiculous to ship.

Make sure you have enough volume in the sump without the check valve. It will fail at some point - usually when you're not home. Murphy's Law.

You mention the return chamber was overfilled in your leak test photo, but it's actually at the level where it should be - it should be about 1/4 - 1/2" higher than the last baffle so that there isn't a waterfall into the return chamber. If you have a waterfall that makes the baffles a moot point.

Looks like it's time to get salty!

When I ran the test in the previous picture the return nozzles were placed high enough and when the pump was turned off they weren't submerged so didn't even use the check valve.

I never thought of that in terms of the water level in the last chamber. Totally makes sense though.

I think it's safe to say at this point that this build is proudly sponsored by Anthony

Had a post up looking for some rock and he was quick to contact me and give me a deal I couldn't refuse
Got them sitting in some water for now to get some of the debris loose



Got a refractometer in the mail but it's taking longer than I had hoped, luckily I was able to borrow one from him



Also a 50g bucket for the initial mixing and filling



Without the help from Anthony this build would've been much more difficult and time consuming. Can't thank him enough!
