Anyone Still Using Chemi Pure?

[ProReef]

Did you give it a light rinse?

[ScubaSteve]

Always, always give it a good rinse before using it!

the yellow scum at the surface does seem odd, can't say i've ever heard that before. But i will do some investigating! Cheers Ronnie

I always rinse it very well. I use it in a canister filter, I do like the results of it. Like I had mentioned before everything growing extremely well with it and I like the fact not touching it for 6 months. But every time I will get the film on top of the water.
