Sump questions?

[Achill3s]

I have decided to get my tank ready to install a sump and not sure how big the sump needs to be for a 75 gallon. I will be keeping an assortment of gouramis, angels and mollies in the tank and won't really go past maybe 12-15 fish in all. I will not be doing a planted tank as i don't have the proper lighting to do so, but that may change in the future.

I have a 20 gallon tall lying around that I plan to turn into the sump, will that be big enough? I know mainly I need to proper flow rate and that has me a bit stumped as well. Is 300 gph enough of a flow rate to filter the tank properly?

Also is it necessary to have the tank drilled or can i do one of the HOB diy overflows? I have been reading up on them and i somewhat understand the way they work but am really afraid of a flood if that were to fail. I can do an internal overflow as the tank could be drilled. Its not setup just yet. Bought the tank for 50 buck with some equipment and didnt' trust the seal so i resealed it and am waiting for the results of the leak test. Giving it a few more days and then gonna start the setup.

Also, with a HOB overflow, is it possible to have too much flow to where the overflow could not keep up or is it generally safe unless it gets clogged?

A 20 gallon should be sufficient for your set up. A DIY overflow is definitely worth it. Also, you will not need to worry about overflowing anything through the overflow. If you build it correctly, it will never pour more then your return pump can handle. If anything its the other way around. You need to make sure your overflow will keep up with your return pump. But, that is what the pipe sizing chart and flow rate sticky is for in the DIY section of the forum. I myself, am building dual overflows in the case that one clogs and I am not home to fix it/notice it in time. Just search around and I am sure you will find all the information you will need. And when in doubt, just ask! We don't bite like our fish!

Hi friend,
I read your message, A 20 gallon should be sufficient for your set up.If you build it correctly, it will never pour more then your return pump can handle. If anything its the other way around. You need to make sure your overflow will keep up with your return pump.
Thank you
