Agree with above.
My Apera 60 does not grow weird white or colored stuff, the way the Apera 20 does.
Monthly cleaning and calibration part of the plan.
Full cal kit support with clean fluid.
Definitely part the monthly plan.
My municipal water is about 7.5
My TPS nutrient feed lowers PH of solutions.
Trying for 6.5 in, and monthly soil core sample slurry for soil checking.
Available options.
