I'm back with a quick Q for a friend of mine who owns a fountain in his new home. (300 gallons).
Just wondering how long the pump should run per day? There is no filter on the pump. The water gets about 6-7 hours of sun.
Current readings are;
FC = 7-8
pH = 7.2
TA = 60-70
CYA = 90 (he was using Chlor tabs for a while, so this got up a bit higher than I'd want it to be)
Model : 50PN2.25S Submersible Pump, Continuous duty
approx 50 gallons per minute
If anyone has any ideas, it'd be great.
