I have recently started dosing my 5 months old 20G, because I realized I had too many SPS and the Redsea coral pro salt wasn't keeping up with alkanity.
Now I'm dosing 2-part and doing a 30% WC every other week. The salt I'm using has elevated levels of elements, cal is about 475 and alk could be as high as 13dkh. I've read that high levels of major elements could effect the colors negatively especially in a low nutrient system. I just happen to have low nitrates because I only have one small fish and lots of high quality LR and I also siphon the sand bed every time I do a WC.
I would like to lower the alkalinity specifically, but it seems my 30% WC would bring it back up to quickly and that might stress the SPS and I could never run lower alkalinity without making the system somewhat unstable. I'm kind of stocked with this salt for a year. I know it's a good salt and I bought it because I thought I was going to keep it simple and never dose, which changed soon after I realized I can't resist buying new corals. :crazy1:
I would like to get the colors I was getting before I started dosing. Should I change the salt? if yes what to? or should I find a middle ground for my levels? If yes what levels do you guys recommend? I'm currently trying to keep the cal at 470 and alk around 10.
