Thanks I hadn't pulled the trigger on it yet but most likely will tomorrow. Did a 30 gallon water change which is close to 10% and levels are pretty much the same 24 hours later. I did find a chart that says the salt I use is high in alk 13 and I'm at 15 and calcium 480 I read 520 and phosphates I can't remember but I'm sure they are high based on the salt. Salt I'm using is the reef crystals brand

I'll probably order a different brand of salt and do small 10% water changes over time to help lower the levels to what I'm reading other sps tank owners are at. I feel it is directly related to the salt I used to begin with
