My experience with osteropsis wasnt awful I was able to cure it in like 2 weeks
I attempted dinox but that made things exponentially worse. What ended up working for me was a 3 day blackout strong uv and peroxide. I had an extremely bad outbreak in one tank and a moderate outbreak in my other tank.
What helped the blackout and peroxide the best was taking out the rocks, scrubbing them with a toothbrush (extremely time consuming) I also filtered all the water in the tank in a 5 micron filtersock then poured it back in the tank. Give it time and you will beat it.
I've included a before and after shot of my tank
I saw the difference in your thread. Very nice improvement I've been thinking of pulling my rocks out and scrubbing them after reading that thread.
