So two part dosing was just becoming a lil too much for me. i was dosing too much and always forgot or did it at different times. i was also having problems with low PH(6.9-7.4) throught out the day. so after trying co2 scrubbers and other things i decided a Kalk reactor would be choice for my system.
i have a lot of SPS and LPS so a steady supply calcium and ph stability was what i was looking for. Picked up a nice big reactor from a buddy and gave it a try. so the reactor had 1/4 in fittings, as its suppose to be fed from a ro/di unit. i couldnt and also wouldnt recomend doing this as the risk isnt worth it. so i used a toms aqualifter pump, controled by my reefkeeper ATO, and it worked fine. this worked great for about a week, then i noticed my sump running low and the aqualifter wasnt pushing water in. after a email to manufacture, i found out the lil pump didnt have enough head pressure to keep up with my reactor.
what to do now, i aquired a box of ro/di gear from a reefer getting out of the hobby and in that box was a booster pump that i couldnt use wth my system(to small). it has 1/4 in fittngs and i could use mur-lok tubing, great!!!
this ended up working fine and having a pump that can run dry was one less thing to worry about.
So after a month of running Kalk(brightwell kalk+2) calc has held steady above 400ppm ph is holding at 7.8-8.0 and coral look very happy and thriving.
