Who's running a Pentiar 25 watt and what flow rate are you running for protozoa? I have found conflicting information. BRS says 79 to 131 gph but I found a thread where someone actually contacted Pentair and they said you can't run the 25 watt that slow due to overheating and or burning out the lamp and melting the housing. Minimum flow rate for the 40 watt is 7.6 lpm which comes out to 2 gpm. That's 180 gph which is higher than BRS and the first flow chart I found says. Minimum flow rate for the 25 watt is n/a
