hi i have a hayward ecostar pump and hayward c3030 cartridge filter brand new, we just had our liner replaced, added 3 loads of water, when I run my filter at 1000 rpm the pressure gauge on my filter did not go up, is this normal? Also I have a cmp in line pool chlorinator, am I running the pool pump fast enough for it to work? I do not see the flow meter moving but i could hear water inside. Thank you.
