Anyone using nitraguard biocubes?

[halwake]

Been using for over a month. Cleaning glass much less, LPS does not seem as happy, SPS looks fine, clam and anemone all good. My RODI unit had put some crap in the tank after the DI resin must have expired and got a cyano out break. This had cleared up now with the cubes, I have heavy fish load and feed pretty heavy as well. Have the cubes placed next to my skimmer output. Seem to do what they say, like I said though, my torch, and hammer coral has not seemed super happy.

Hope this helps.
