yes it has its own pump built into reactor and u control the flow with a pinch valve but the output is way to fast instead of drips so i put a pinch valve on the out flow so if the input drips are faster than the output the unit starts to overflow and if the output is faster than the input the unit loses suction and quits pumping inflow water and drains the unit i dont think the ouput is even suposed to have a valve but i cant stop the water from shooting out way to fast somebody just kill me please
the directions say no i need nothing further than whats in the box and beldts aq. in st. louis says same thing the coralife reactor has only one pump and thats all u need even the end u put in water has a screen to block clogging i wish these guys that sold me the 1200 dollars worth of tank, reactor, regulator, ph controller could tell me more but they cant figure it out or they just dont want to
i have never used the coralife reactor but i can't see how it would work without a circulating pump and a feed pump. read this and this will show you how to set one up. it also isn't a coralife reactor but it is how you set up reactors.
sorry for not being much help but after looking at the very confusing instructions the only things i can come up with are.
do you have the intake strainer 6-8" below the water line? sounds to me like either the intake isn't far enough below the water line or you have a line that is not fully connected and is getting air in it.
Mine is a MTC reactor and sounds like a similar setup. The recirc pump draws water in without something extra. I get a pocket of co2 in the top of the first chamber from time to time, but I never had the intake not work. Like above, check the input connections and make sure they are tight.
ok it was what i thought input and output drip need to be the same or it overflows or drains, so it has been running good for 24 hours and i measure the output drip into refugium and calcium is high and ph is 6.8 same as reactor ph will this low ph drip lower the tank ph at some point
