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?

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