Need advice on a DIY 120 fixer upper.

[jctse]

Need some assistance on a 4x2x2 fixerup tank. It's missing the baffle in the back right corner so I just have 2 holes in the bottom back right (1-1/2 and 1-3/4). The baffle on the back left is still there but the 1-1/2 and 1-3/4 are just holes and there's no bulkheads. I have an extra 29 Gallon Tank that I would like to use as the sump. I currently have a kessil a350w and plan to get one more for this. Planning on Mixed reef and not really big on fish... more on coral. Been doing 2 nano reef's for about 3 years but never even had a sump.

Initial questions are do I need both baffles or just plug up the right two holes? If its better to have can I just have TAP (or the like) just cut some pieces in and create one. Is that size sump adequate?

Big Thanks for any suggestions you can offer.

You don't really need 2overflows many 120 tanks have only 1 it will decrease the amount of water you can turn over through your system. So ya could just put in bulkheads then plug them.

Great! SORRY for my ignorance. I realize it's an overflow that I'm missing on the one corner LOL. But cool. I'll just plug them up.

You do need to be sure however that your single remaining overflow box has enough linear inches of overflow teeth to handle all the water flow you intend on running through your sump.

And that you are planning on less than 600 gph as that's the MAX a 1 inch drain will handle. Imo it's more like 500 Gph for practical use. I am guessing the single overflow is the standard curved corner one that comes in an aqueon tank
