So I have a new Lifegard Pro-Max 55watt UV going to add to new 210g tank setting up.
The tank has 3 holes drilled in bottom of tank for closed loop. (2j 1” and (1) 1 1/4” bulkheads. I was going to gravity feed from the 1 1/4” into the inlet of the UV. Then use outlet to return water to the (2) 1”.
So questions are where should I install my DC pump for return since need push water up back into tank. Before inlet to UV or after? My thought was after. Also I have 1” Neptune flow sensor would like to use so can dial in flow. Which now brings next question. Should I use ball valve anywhere in this to help dial it or so just use DC control on pump?
Please looking for advise soon. Need get on this to replace kids leaking reef tank.
