I try to calculate your tank volume, and found that your total tank volume is at least 890L ( 60% volume in sump and the water depth is 28" in main tank ie. 606L + 0.6 x 471L = 888.8L ) But the pump is required to have at least 10 times the flow rate of tank volume, therefore, pj 10000 can only meet the lowest requirement of circulation and it is not include the problem of current in tank, I may agree with that 2 pj 7500 pump is the best. ( just share my own opinion.) |
