A couple of days ago, finally received RKL SL1 module and BRS Ph probe. Had all modules/head unit firmware upgraded, hooked up Ph probe, calibrated and let it run.

My low Ph (before lights on) is 8.00 and high Ph is 8.4 (before lights out). I guess the levels are ok.

I did my monthly water test today. The results are

Nitrate : 0ppm
Phosphate: 0ppm
Ca : 220 mg/L !!!!!!!!
Alk: 12 dkh !!!!!!!

Turns out my 2 part container, the Ca part, was still full! It took me a while to figure out what went wrong, it was because the lid was shut and completely sealed the container, and the poor aqualifter pump could not suck the liquid out.

I took out a drill and made a small hole in the middle of lid on both containers..

Nothing really were obvious in the tank, but I noticed RBTA moved down a bit and found it strange for days..

I think I avoided (crossing my fingers) a near disaster
