![]() Yes...or add slightly less of whatever balanced supplement you are adding. Natural usage in the tank will bring the levels down if you don't supplement.

Do you happen to have a very clean, fish-only system? I'm baffled by that one.

![]() To give you a little more info, my salinity is a 1.023. I have not been dosing anything for quite a while now, although I did up until about 7 months ago using Reef Complete. I have mostly softies, but a few SPS as well. I also have a reasonably decent Bio-load with 10 fish in a 70 Gallon tank. I don't have an RO/DI myself, I purchase RO water from a local vendor (same stuff I drink). I don't use any tap water and have not used any in 2 years. I don't have a lot of new coraline algae growth, but my rocks are nicely purpled up from the last few years.
Any other suggestions? Quote:

![]() mseepman, I am at a loss to offer an explanation.
There is no mechanics that I can think of that would allow Ca/Alk to go UP beyond the levels of the replacement SW in any system that is supporting SPS and coraline algae. I don't think that fish or overall bioload are a factor as they don't pull Ca from the water.

![]() In order to try and bring things back into line, I am doing a 20% water change this weekend. I did a 20% last week as well but it didn't seem to do much.
Without having my own RO/DI, big water changes are a real pain in the butt!

![]() I do...have you checked for a faulty test kit. What test kit are you using..A lot of problems with Salifert as of late, could be your alk or Ca test kit.

![]() I thought the same thing...but I have a Hagan test kit and the Salifert and both read similar. I bought the Salifert kit after getting these readings from the Hagen kit. I have a friend with a red sea kit (ugly I know) but I will have him do a test and see if he confirms.

![]() Test the RO water you are buying for Ca, not being run through a DI filter I'd bet it contains Ca.
As mentioned by Scumchug, you are then adding Ca everytime you top up your tank and slowly increasing Ca levels.

![]() I will try testing it, but wouldn't it show when I test my newly mixed salt water too?
