Calcium reactor flow?

[dmay2782]

How much flow is needed to a calcium reactor sized for a 75 gallon tank? I plan to T off my return pump just want to make sure I size that accordingly. Aproximate GPH for reactor would be helpful to know.

shoot... I mean just whatever your target effluent rate would be. So pretty darn low. Mine is like 60ml per minute or something (60 - 70g totals system volume), basically as fast as you can drip without becoming a stream.

My reactor feed comes off a manifold supplied by my return pump. The branch it's on is just a 3/4" ball valve that has a 1/4" John Guest fitting in the end of it. The actual line to the reactor is 1/4" icemaker tubing or whatever.
