DrTim's Aquatics Reef Clear-Up 4 oz

Amazing. This thing, used as directed, cleared my water overnight after days of being dusty from pouring in new substrate. Today I needed it again after a few months, because I moved things around with a water change and same thing: my water is crystal clear. I combine it with a water polishing floss in the media cup and activated carbon for best results. Also, having cancer running in the family what I love about Dr Tim's products is that they are not chemical. I would love to keep one of this around like I keep other Dr Tim's products, just need to double check on shelf life as these are live cultures. I would recommend this to a friend for sure.

Nothing to like about it. Didn't work at all. My fish tank water is still cloudy

seems to be working on the well water in the aquarium.

Great value works well.... Though the actual size of bottle and volume of fluid inside were both smaller and less than advertised...

does exactly what it stated it would do. Clear up my talk water without harming my fishes.
