I use IO and use turbo calcium to up the CA to 420 and buffer the alk to 4 meg/l after mixing in the salt to 1.026. I let it mix for a day and then do the WC>
What brand of IO do you guys use. Can not find Tropic Marin around here. I can order over the internet though. Is it worth it or what brand of IO is comparable?
I use Instant Ocean=IO it is the only type. If you have a Petsmart near you print out the online price of the instant ocean bucket and bring it to the closest petsmart, they will match they're own internet price this is the best deal around.
