2 sumps on 180 gallon
so I was going to try 2 sumps one 40 gallon
rubbermaid that house my skimmer, heaters reactors, then drill bulkhead and have it drain
into 30 gallon that would have a refuge and return pump if this would work ?
With an auto top off and when the power goes out
if there will be enough room for extra water from the return pump thanks
