Another problem is i dont have a temp tank i could move everything to in order to drill, i assumed drilling with livestock in the tank would be.. well not recommended to say the least. Looking at the prices of the higher gph cpr overflows im wondering if upgrade time for the tank with panes im able to drill might be the cheaper and better way to go in the long run...

if you have a tank thats already running and your already planning an upgrade then i would save that money you would use on an overflow and put it towards your upgrade......buy only what you need and can use for a long time:)

a temporary tank while you drill can easily be just a large bin hasnt got to be pretty just large enough and safe enough for your livestock.......hang a little sign sayng construction in progress lol but i would just save for your upgrade:):) cheers:)

I would would have to agree with reefwars. If you are eventually going to upgrade, save the money and get a reef ready tank. People sell them on here all the time.

I ran a CPR 102 on my 65 gal hex without an issue. If the power went out return pump stopped. When power came back on return pump and airlifter kick in and kept on working. I live in the country so power flicker often.

Best way to test for tempered glass is polarized glasses and a laptop. Laptop needs to be at a 45 degree angle to the glass. If all you see is a TOTALLY BLACK screen, not tempered. If there are white streaks in the black it's tempered.

Hahaha yeah thats a good point, I have a couple 20gal Rubbermaid tubs ive never used in the garage i suppose thatd do it. Ill have to sleep on it, a drilled tank being next to 'foolproof' does sounds alittle more attractive.

Thanks for the comments everyone.

That would work, just make sure that you have everything figured out and pre-built especially if you have to silicone in an overflow. Keep your tubs heated, lit & skimmed and you will be good for a few days any way.

If it drillable, that would be your best way to go.

Overflow box advocate here...lol
People who tell you having a drilled tank is better or safer just havent used an overflow box before or did not understand how to properly set them up.

I have a drilled 50 gallon and a 95 gallon with a u-tube DIY overflow and neither has ever flooded or caused a problem.

IME, you don't want a CPR overflow though, the ones that use the aqualifter to start siphon again are nowhere near as fool proof as those that dont require restarting at all...

like this one.
