Hello everyone. It's been a while since my absence since last summer but I am returning back to the hobby slowly as in taking my time in building a filtration system for my 450 gallon. Anyhow I'm having issues on trying to get my tank drilled as local places are charging me an arm to have it drilled and it must be on it's side for them to drill it which the tank is already levelled on it's stand and against the wall. The tank weighs half a ton so it's hard to find enough peeps to move the beast. Also the bottom cannot be drilled as I don't want to risk it cause it's tempered. So I thought about using overflow boxes which HOB of the tank. So I picked up a used CPR cs150 but that didn't work due to the water intake of the box sits higher then my max water level in the tank due to the euro bracing all around the tank. Now I've checked out Eshopps makes overflow boxes. My question is does anyone know what's the measurements on the hanger of the box on the pf-1800 model and how deep does the intake box sit inside the tank? I need to know wether it'll fit my tank as my tank trim is just over 1.5". Also would this work 2 x Eshopps pf-1800 draining into a 90 gallon sump with a 2800-3000gph return pump @ 5 ft? I need some answers before I start my sump project.

Thanks help much appreciated.
 
I would like to but I'm no handy man and I don't want to risk cracking the glass. Also if I drill it I will drill it on the back of the tank but the tank is already against the wall and it's very heavy to move...Like I said it's hard finding 6+ peeps all at once to help me move the tank...It took 7 of us to just get it on the stand properly alone...

Does anyone else know about Eshopps overflow boxes? Or any other kind of overflow box I could use besides CPR?
 
i would honestly think drilling it yourself would be the safest way...i mean..how safely do you think you can
1) move a 1000lb tank with a tempered bottom (if that drops on its side..look out) into a shop, drilled, then taken back again and put on the stand..

now, does it sound more simple to:
2) pull it out a little from the wall, drill it, push it back, Done..

.i think #2 would be smart..just practice cutting on a piece of glass if youre uncomfortable doing it.
i just see that tempered bottom being a glass grenade if you drop it or bump the tank against the transport vehicle too hard trying to position it.

I know the best way is to drill the tank but that's not my question here...My question was would the overflow box idea work? I'm looking into Aqueon Overflow box rated 2200gph x 2. I just want to know if they actually work or not. Sorry I don't have the balls to drill a tank and risk cracking it and spending thousands to replace it... If anyone else going to reply "Just drill the tank" please don't bother replying...I'll find my answers and help else where...
 
Oh hey, welcome back.

If I were you I would practice drilling on smaller tanks. Then drill your monster. Not that hard after you drill a few holes.

They work, but if you want them to flow properly 1 1/4" plumbing as min is a must.

thanks rhodes_96 for answering my question. So the drain plumbing needs to be 1 1/4" minimum all the way down to the sump? Would I be able to use flex tubing instead of pipes so less bends for a more efficient flow? On the overflow box itself has 2 x 1.5" bulkheads for the drains. Trying to set up my overflows and sump the most basic and simplest way here.
