Thats a good question. I have to take it to go get tested this weekend because I dont have a good test kit. I know I need to invest in one but I just cant afford one right now. If I buy one I want to buy a good one and not a crappy one. What would I be looking for most that would cause this kind of change in coral? I know everything is important, but I'm just curious as to what levels are most important. I know my calcium is good because the last time I got it tested they couldnt read it because it was so high. Then again it could have been their test kit being bad. I use Oceanic salt and do a 10% water change weekly with DI
water. I don't have a RO
unit yet but I have a DI
that I got from a friend that hooks and unhooks from my tap pretty easily.
