aqua medic 1000 what is the best pump for this co2 reactor, i have it underneath my 110g tank, right now i have a 500g pump with a diy co2 reactor hook up frist then into the aqua medic then to the return pump then out thru a 300g hydro heater, my diy reactor stays nice in full but the aqua medic i have to keep purge it because the water lowers down,i have a lot of tiny bubles in the tank, should i put a smaller pump insted of the 500g pump, an should i take a air line to the purger and tee it back into the aqua medic, i can hook it into my diy co2 reactor it has a 1/8 brass hose barr tapp into it already, any ideas pleas |
