How do you clean your aerocloner?

[LOC NAR on probation]

What is your water temp at? I noticed if my water goes over 72 that it takes longer to root and the roots look unimpressive.

The water is 70 to 72 never more or less unless I set it.
R/O water PH'ed to 5.8
A few drops of superthive.

On the last run one or two started roots at 2 weeks so I said to hell with it and put lite nutes GH 3 part and that's when I got the 50/50 turn out.
before that was way worse turn out.

We were trying to get away from rockwool or any starter blocks. I have seen areocloners do very well but can't seem to tune this in.
