Currently my QT setup is two 20L tanks one for fish and one for coral. I was wanting to combine both of them into one tank maybe a 30L or something close to that and putting in glass dividers so there are 3 sections. I was thinking of drilling 1/4" holes in the glass. Has anyone tried this I'm pretty sure it would work just want some opinions.
dividers in a Qt tank even if drilled would reduce water circulation (Flow)
you can keep a fish and coral together why divide it , I divided a 20L but I also had to rig a pvc tub connected to a strong power head just to get flow to each section and that was no easy task
