Transforming a drilled tank

[caitlynnanne9189]

Have a question. I have a 75 gallon drilled tank I bought to do a reef project that in my current position is just not plausible. I really don't want it to just sit, can I do anything to block the overflow and use it as a freshwater with a HOB for now?

Yes you have a few options. You could put a bulkhead fitting on it and cap it off. They also make rubber plug type things at the hardware store that has washers on both sides and you tighten it down to seal the hole (sorry can't remember the name of this one). One thing I've also done with many tanks is just use a small piece of glass over the hole held in place with silicone.

I have siliconed a piece of glass over the drilled part in several tanks, works very well, just looks a little unsightly. Plant a tall plant on each end to cover them up
