I dose kalk and components 1,2,3 from Aquaforest as well.
The reef moonshiners method is great for not doing water changes as well.
I like to compare my tank to others that run calcium reactors, because that media itself puts trace elements back into the water. I have been in this hobby for 18 years going to 19, and I’ve killed sooooo many acropora and always had stable parameters.
I think having trace elements available in your water allows acropora to handle stress better. For example, alk swings a bit, no problem… for what it is worth, I think moonshiners does a great job at targeting depleted trace elements that DO have biological benefits to our corals. I love when people say they don’t dose anything yet have a huge calcium reactor. The media itself is releasing trace elements into the water.
Moonshiners is a method, and it works. It’s saved me hours and hours and thousands of dollars because I don’t do water changes anymore in my 200g tank, and I don’t have to make as much water so RODI filter savings

.
In fact, my tank pays the electric bill, food for the tank, AND for more coral on a good month. What I mean by that is that my corals are growing so dang fast I have to sell mini colonies (10+ heads colonies of all kinds) to make sure my tank isn’t taken over by zoanthids.
Idk, for me it works and I’m going to continue reefing this way.
