Kalk stirrer online tonight

[DJ88]

In some circles people think that the kalk works in phosphate removal from your tank by bonding to it and being removed by the protein skimmer. I am not 100% convinced but when I was running the kalk stirrer before I didn't have the bryopsis problem.

I have run the two together before and want to see if there is any difference from when I was running Ca Rx alone to the two again. I am looking for coral growth and less algae.
