kalk reactor questions

[jonathan543]

should the pump connected to the kalkreactor be on a timer? if so how long per interval is recommended? is it advisable to keep it running all the way because the topup occured several times in an hour... think because i'm using 5fans on my 2ft tank & 2more in my refugium haahaa... pls advice! =)

I run mine on a timer, 15mins every 1hr... from what I understand it's because you don't want to stir up the undissolved kalk but rather just stir enough to replace the solution which leaves the kalk reactor...
