Upgrading sump pump.....

[Bob 1000]

What's the longest I can have my sump pump (main pump) off???

I will need to re pvc and glue on a new return line...Had 2 now I want to change to 3....

I have a total of 3600gph in power heads in my main tank...

I will need a minimum of 6 hrs for dry time I believe....

Thanks in advance for the knowledge...

You'll be fine, since there's still circulation in the display tank. What else is in the sump?

Some type of long, fingerlike caleurpa... Blue line grouper and panther grouper the sump has about 2000 gph in powerheads... What's the longest you think I could go???
