pearling stops for a day or 2 after water changes
Okay, so my plants usually do some moderate pearling in the last couple hours of the higher light phase of my tank (finnex 24/7). This is except for the days following a water change, which seems counter intuitive to what i have read about water changes and pearling. I just did a minor water change the other night, about 10% tank volume as opposed to the usual 30% to see if this still affected and it did, (ie, no pearling today). Its not a problem of course but seems odd, and if anyone could enlighten me I would appreciate it.
33 gallon fluval studio tank
pressurized co2, with inline uv sterilizer modded to be used as a reactor, limits total co2 but i see a ph drop by 1 degree
fertilizers are added at water changes only, every 5-6 days( pinch of potassium phosphate, tsp of gh booster, and usually add 5-10 osmocote granuals into substrate monthly
Measured nitrate after last partial water change and read about 20-30 ppm, with uncalibrated api test kit, only thing that came to mind was reduced nitrate after water change but minor water change still affected pearling
Thanks in advance
