just a simple question: how can I clean my rhinox diffuser? currently the ceramic plate is covered with brown algae and I have the idea that this clogs the plate, which results in bigger bubbles. How can I clean it?
Yes, what Tom said. I like to CAREFULLY suck the bleach through the ceramic plate by sucking on the glass tube, then shaking it out and rinsing, and then sucking dechlorinator through the ceramic plate, then fill it with water and rinse it out and shake the water out. It gets the ceramic plate really clean, or you can fill the diffuser with bleach/dechlor and carefully BLOW it OUT of the diffuser through the ceramic plate. This also gets the plate clean all the way through. But a good soak in bleach&water and then in dechlor. works just fine if you dont want to put your mouth up to bleach. Its real easy to get bleach on your lips and tongue if you're not careful.
I use the Excel method. Raise the diffuser out of the water and pour a capful of Excel directly onto the ceramic disk, let it soak for a few minutes and that's it. No need to worry about bleach or dechlorinating and the Excel will be good for the tank.
Well, I also thought H2O2 should work equally effective but it didn't. I tried a new solution at 30% strengh for an hour or so. Bacteria might have been killed but algae seemed to persist. Anyhow, the diffuser did not at all turn white as I was used to seeing it with ADA's Superge. I gave up on trying peroxide.
I also have a Rhinox diffuser and I really like it!
Some days ago I soaked mine in a 2% "klorin" (probobly not the english word ) solution diluted with destillated water for 24 hours. After that time the diffuser was cleaner than when I bought it!
After soaking in klorin i washed carefully with water and I also soaked it in destilled water for some hours before putting it to the tank again. It worked very well. I already see it begin to come even more algea of the glass diffuser
