30 second Ultralith challenge

[Sebae again]

Sorry, I have no photos. Ulralith is made of zeolite rock. Reefresh is a different system so it can have different effects. If you take a look at the OA tank, especially in person you can understand why people are in support of this system. Like many other things,it's important to follow directions and have a little patience. I myself noticed good results in 2weeks and exellent results within 4 weeks. This is in a 90 gallon with 10 fish in it so results could very depending on bioload.
