I have a dkh of the effluent of 28 and a dkh in the tank of 13.44 and a ml/min of effluent at 25 ml/min. To me this seems low ml/min. Is that the case?

dont go number chasing. if your levels are right then i wouldnt mess with it darrin. whats your calcium at with that dkh?

When I was doing the tests I was also going to check the calc. but I ran out of #3 @ 10 drops so I have to go and get another kit or refill. I was using a hagen kit is there another one that anyone likes better and for what reason? thanks

Darin, do a search of the board for Hagen and you'll find a few threads dealing with opinions on test kits.
