Instant Ocean for 4 years, just switched to Reef Crystals. The IO = very high alk but low calcium. I seriously can't complain about it but I decided to go to reef crystals for the extra trace elements which in a newly mixed batch were decent. Alk was average, between 8-9 much lower than IO but calc. was 450, much higer than IO. Iodide and Iodine contents were right on the money. Mg was a little low at 1100. Strontium was a little low at 4 but the error in the salifert test is +/- 5 ppm so who really knows. I supplement Mg and strontium anyway.
I bought a 5 gallon bucket of the reef crystals from the LFS because by the time you pay extra shipping, you may as well just buy it and take it home. It'll last me a year. It was 64 bucks with tax. Probably too much. The place is usually a rip off.
