I'm new to salt water, so please bare with any incorrect terminology.
I am trying to design a sump for a 90 gallon FOWLR tank.
I'm picturing a three stage sump - skimmer, cheato/live rock/pod breading area, and return pump.
I'm deciding between a center return with the main flow going thru the skimmer side and just a trickle on the cheato side and both spilling into the return area.
or a skimmer, then cheato then return format.
Some of the things I've read said that it has to be low flow or the pods will all get swept out.
But it also says that low flow is bad for the cheato.
Other posts I've read say that if there is enough live rock for the pods to hide in,
then doing the cheato in the center stage with a higher flow rate would be fine.
which one is correct?
Is "Rolling the cheato" in water flow, benefitial or unneccessary?
Thanks,
