Sump intake and output baffle dimensions
Does it really matter how much space is in the input and output side of the sump? I want to maximize the size of the refugeium by having as small of an intake chamber and as small of an output chamber as I need to have. Normally I would test the **** out of this but right now I don’t have that luxury.
As an FYI this is a 10 gallon fuge and there will be no skimmers or reactors in it … they live elsewhere. This is strictly a refugium with a chamber to hold some carbon and macro algae. Do the input and output chamber sizes matter or is physics physics … water in water out? |

The output section is the only section that will drop with evaporation. If there is not enough water in that section then your pump will suck air frequently

I will have an ATO ... but I don't want the ATO to start pumping fresh water in because the sump input (overflow) cant keep up with the sump return.

The water entering the sump will be equal to that of the water leaving the sump. You won't have an issue with the return section being short on water unless evaporation takes too much water out of the system

I never use baffles in my systems. Even in my multi-sump/refugium setups plumping/openings are designed so all the sumps/refugium have water levels stay the same irregardless of evaporation.

The "output" area should not be small - even with an ATO IMHO - and I would recommend at least a 3rd of the sump. The flow through your in-sump refugium should be non-turbulent. Ideally your skimmer should output to a section distal to its input. Also, your sump should be the absolute largest that you can fit into its allocated space. $0.02

My two cents:
In most cases - multiple baffles serve no purpose. A single "over" baffle creates in intake compartment and a return compartment. More often than not, the multi-baffle setups end up wasting space and the baffles are so close together that bubbles are whisked right through, defeating 90% of the reason for the multiple baffles to begin with. Refugia - Another complete waste of time. Copepods grow anywhere; as do most things. Refugia, more often than not, become nothing more than hard to clean detritus traps with little to no benefit and plenty of headaches to maintain. Live Rock in sump - nice idea ( i ran 100+ pounds there for years) but another detritus trap. If you do this, maybe big chunks that can be easily removed and swished in a bucket. Just my two cents... not that they have any value to anybody but me. |
