No need. There are no chloramines added to the water here. Have been running the same way for 5+ years.....are you putting water conditioner in the new water from your drip system. I have two 420 gallon tanks with drip system and every night I add pond prime to the tanks and I change 100 gallons a day. The pond prime winds up coasting a lot less than regular prime because it is more concentrated and it removes ammonia and nitrates that could be your problem
Wasn't aware of any problems here besides ray pups being sensitive to drips, likely from the ammonia byproduct of the carbon removing the chlorine. The 2 bigger systems (600 and 1K) both have rays and drips and there's no issues.
