Ph dropping

Are you using a controller for your Co2? The reason your Ph is dropping is because adding cO2 to your reactor drops the Ph inside the reactor to 6.1-6.5 to dissolve the media slowly making your effluent rich in calcium and alkalinity. It also drips into your sump at that low of Ph and on small tanks can drop your overall ph. Adding an effluent chamber will help, also dripping it into your fuge will help as well as your macro algae will use up the some of the co2. What size tank do you have?

60 gallon might be a tad small for a calcium reactor. Just watch your Ph don't try a buffer it will just make your alk go through the roof. I would look into an effluent chamber to help raise the Ph before it re enters your tank. What is your Ph inside the rector?

If your calcium reactor has two chambers, then that's what the second chamber is for, effluent. What brand of reactor is it? That should help raise your Ph a little before dripping in your sump.
