I have read that adding hydrogen peroxide to the tank can reduce or kill off the rather thick brownish and a patch or two of red slime coating on the sand bed . . .
Thank you SO much for this post! I had always wondered what adding hydrogen peroxide would do to help, but never came across any references to it in my browsing of aquarium related chemical additives. I have a similar issue, and will begin adding Hydrogen Peroxide asap to see if it helps.
Having had a rough year with the aquarium due to neglect on my part (a divorce and all the drama associated with that distracting event), things have been challenging to get back on course now that things have calmed down.
My fish are fine, but my corals began to die off, and I couldn't figure out why.
Currently my stats are:
1.024 specific gravity, 0.02 ppm Phosphates, 0ppm Nitrate, and about 40 ppb Nitrite. PH is hovering around 8.1, and Calcium is up about 520, with Mg up around 1500, dhk is around 7.8 as well. So it doesn't seem like a chemistry issue, unless having too much calcium and Mg is bad.
I began adding vinegar, 1ml per 10gal, a while back to control a bad nitrate spike I had, and it seems to have worked well to get things on track. I also recently began adding a Ph Buffer to try to raise my PH, as I was told 8 was too low.
I also experimented with adding Sodium Silicate, Ferrous Sulfate Heptahydrate, and Potassium Chloride. I noticed a growth and brightening in my surviving corals after adding those chemicals, however no change in the amount of cyno / hair algae.
I look forward to see results of hydrogen peroxide!
