Ok seriously we can't read minds:

1. What kind of standpipe are you running?
2. Do you have a hole drilled in the cap? If so what size?
3. What size is your drain (bulkhead size)?
4. What size piping is your standpipe made from?
5. What size pipe did you run for the drain from the tank to the sump?
6. What size return pump are you running? Estimate on actual flow rate to tank?
