I have an LPS dominated tank but I also have 10 Tridacna clams as well as some acros and other sps. I haven’t really done any deep look into my parameters but I try to measure my calcium every time before my weekly 25% water change (10 gal / 40 gal) and my calc is always pretty high. Should I just reduce my water changes to every two weeks? I don’t know if all for reef is helping or if I should use something like acropower, so my question is really just if my water changes are too much or if I need to dose less. I dose about 5 ml of AFR daily. I would also like to mention all the corals and clams are doing better, but I just want to make my supplement or salt last a bit longer lol. I also use reef crystals as my salt mix.
