The first time I tried it I wasn't impressed. Apparently it has quite a bit of borate in it which throws off your alkalinity readings (apparently it raises your test kit reading by 1dkH) and I dunno, but it didn't do the greatest thing for my tank, not to the extent of Colins tank though but my corals weren't happy and neither was I. In an emergency a couple of months ago I had to pick up a bucket of it as nothing else was available. It was fine for the waterchange I needed to do but after that IO became available and I ended up mixing the two together to offset each other and am now down to just the IO. I would certainly never use it on its own again and hopefully will be trying some Tropic Marin Pro soon.
