Here is my Facebook marketplace place 40 gallon with a home made PVC AIO baffle. Siliconed in with GE silicone 1. I transferred everything from my 29 gallon nano to this one.
Here are some pics of my 75 gal
It has HOB aqua clear 110 filter and a protein skimmer from Amazon. The lights are Nicrew saltwater lights 48 in long. There is about 150 lbs of rock and 2 in sandbed. I broke down my 29 gal and put it all in the new tank to make the cycle a lot shorter.
