Instant Ocean reef crystals

I've been using reef crystals for approx 4 yrs now . I find cal, Alk & mag way closer to needed parameters !

I have been using it for the last few months and have been quite happy with it. I don't have a ton of corals, mostly LPS and a few softies and everything is happy. I started using it after seeing the Fragbox owners mini reef tank on their website. The tank looks great and it is skimmerless and no dosing, just Reef Crystals. I haven't had much free time this summer so I haven't really done much in the way of testing, my visual diagnosis is no nuisance algae and corals are expanded and growing. So the tank likes it anyway.
