    DIY Polycarbonate Sump

    I'm going to take a crack at building my own sump for my 125 mostly South American 125 gallon aquarium. I have been using the one in the photo for 3 years now and it's okay but it was originally designed for saltwater and I'm hoping I can do better. The planned dimensions are 48" x 15" x 15"...

    Problems with overflow too slow

    I'm trying to do this overflow system: So I found some flexible pipe for a good price and a diagonal T PVC pipe. (Ignore the grey tube, is my current filtration) I filled the tube till the top, and suck the air out of the first curve, making the siphon until the T joint. I positioned the T...

So I got a used 555 liter tank (~150 US Gal) and I want to make a sump system for it. I already bought the bulkheads and the pump, but not the stand and the actual sump...

    How to measure bottom panel thickness?

    Hi, I know it's a somewhat weird question. But does anyone have a way to measure the thickness of the bottom panel of a tank? The tank has a bottom trim that is glued on so it isn't visible from the side. I can measure the side thickness and assume they're the same, but one can only be so sure...

    HOB Overflow Question

    I have a 125 gallon that I'd love to switch to a sump (instead of a canister). However, I keep my water level about 6 inches lower than the top of the tank (I have mudskippers and they need some room above water). Is there a ready made HOB overflow that is big enough (or can be set up for) a...

    30 gallon budget reef ready build!!

    Ok so I figured I’d document my project and share it with everyone, since I couldn’t find any rock solid info on retrofit overflows online. This will be a build thread that I will update as I go along. The Idea is I’m trying to keep the budget as low as possible. The tank was from the dollar...

    Cheap DIY Filter Sock Holder

    Had an "aha" moment looking for ways to DIY a filter sock holder for my sump and figured I'd share since I haven't seen it anywhere. I used a styrofoam block to hold up the plastic ledge of a filter sock within the chamber. Styrofoam is impossible to sink, pretty much free, and I'm assuming is...

    Thinking about setting up a drip system for the first time with my setup. Right now my sump is currently laid out like the diagram below, with a drilled hole in the top corner. I'd like to use this existing hole as opposed to drilling one where the pump chamber is. Would this still work? Are...
