i'm struggling to figure out the most efficient and well-designed way to go about incorporating my 46g nem/clown tank upstairs with this 265 build downstairs. i think it would be best to combine the two to minimize equipment, maintenance and have one fish room and system aside from the breeding system which will be on the other side of the basement. the only think i was thinking of is that if the upstairs overflow ever clogs, i'll have 265g+ of water pumping up overflowing upstairs and that worries me.
i have a glass-holes overflow on the tank upstairs. i was thinking of taking my return (3/4") from the tank upstairs via bulkhead in the tank and removing it. then using that as a back up with a 1" reduced street 90° in the tank facing up. and use a sea swirl to the existing braided pvc line for the return. problem is the glass holes overflow is a 1.5" opening/bulkhead and the drilled return being 3/4". if tune the water flow for the uptake of the 3/4" then my flow decreases dramatically and i'm a firm believe in not having powerheads in a nem tank. then again, how likely is it that something will block the overflow? if i ran it without it's cover plate then worse case it gets sucked down into the overflow, right?
i also don't know how to design the pump arrangement downstairs. i imagine i'll have a separate pump downstairs from the main sump for both tanks to pump upstairs to this one externally run from the sump through a bulkhead in the return section, then another pump externally run to a manifold for return to the 265 and peripherals?
i plan to have a 20L or so for macro and don't know where would be ideal in terms of plumbing for it's placement nor idea placement in the filtering process, perhaps fed off one of the manifold's outlets and then overflow via bulkhead back to the skimmer section of my sump?
how many outlets you think i need to have under the stand? i was thinking with two quad-outlet GCFI, i should be fine, right? i have an apex now from the GB i just put together and have two EB8s i'll probably put to use and then one of those dj strips perhaps so i dont think i'll need too many, right?
then lastly are water containers. at the moment,i have two ~30g brute cans i use for my 46 upstairs and they work well. i was thinking of upgrading to a 125g fresh water and around 100g salt water so that i have a nice supply of salt water always ready for the AWC system and any emergencies. thoughts? i prefer to have a separate fresh water bin and run my ATO off of that vs refilling a saltwater bin with RO/DI for a day and then adding salt. that would also leave more room under the stand without a ATO container there. do you think i should larger or smaller on these sizes? with the removal of the water heater in favor of a tankless water heater, that will clear up quite a bit of floor space for storage containers so thought i'd take advantage.
i really need to sit down with a designer or get my hands on sketchup and draw this out i think.
any input on the above would be greatly appreciated!
