I am still on the trial period but think I will stop. When I first started in my 90, I noticed a clearer tank. After a few more doses, I seen some
coral extensions but now that I am getting low on the trial bottle about my 9th dose, it is not as good as it once looked. Z's and P's shrunk while my Acans shrunk. Most of the other corals really look the small as before I started dosing. Weird because all my parameters are in check. I do regular water changes, feed appropriately...It went for looking real good to just blah now...so I am going to stop and see what happens. I don't have that much of an algae issue except bubble algae which I got under control. I'll keep watching my parameters just to make sure something isn't out of whack.
