I checked my records from 2010 and 2011. The first time I tried the pellets in 2011 my KH was at about 11dkh and the second time in early 2011 it was 8-9dkh. However I usually keep it up at about 10dkh as it helps to keep the systems pH a little bit higher. ~8.1 in the summer and ~7.9 in the winter.
I haven't tried potassium yet but I think I'll give it a shot. My other two Montipora colonies are still a bit light in colour but at least they continue to grow.
I have several fish with eating disorders so I need to ensure that they are well fed. My CBB will experiment by nipping at new coral if it doesn't get 3 feedings a day. The powder blue tang will consume soft corals if it doesn't have a constant supply of nori. And the snowflake moray gets a little too adventurous if it isn't sated three times a week.
