anyway, i used the dosing pump to feed the DI unit and then try to adjust the flow rate by putting a flow valve ....end up the water seep out of the canister slowly..even though very much tightened...
so much pressure from a 5w peristaltic pump.....no wonder can pump up to 10feet....5watt pump 10feet....
so i have decided to tee-off from a pump when my calcium reactor comes
anyway, tested the water from the DI canister, nitrates 0, phosphates 0.....but......dunno how long it can last....wait a few buckets have to change canister, then this DI unit not cost effective liao...
