I agree with this, I started slacking off a few months ago and my Alk
, Cal and Mag all dropped way too low. A month ago I bought all new "high end" test kits (makes a big difference for certain tests) and started testing at least Alk
and Cal daily and dosing daily. I have learned what my tank needs to stay stable so I will eventually switch to once a week, like Kurt. By the way, my corals are looking much better and growing good again. I didn't start testing daily until I lost color and PE on one piece and was getting very slow growth on the rest of the pieces. I also started developing valonia (bubble algae) It probably took me at least a couple weeks to recover everything.
Another mistake I made was I didn't recalibrate my refractometer for months and months. When I finally recalibrated it with distilled water, the refractometer was off so I readjusted it back to 0. Then I purchased some refractometer calibration fluid and found that distilled or RO
water is a bad way to calibrate. Again I was off.... my reef tank was around 1.022 while I thought all along I was at 1.025
