Hello- I recently used Razor in a 26 gallon nano tank. The tank had overwhelming bubble algae I had attempted to get rid of for months. The tank consists of soft corals, an alveopora, and a few fish. I had to use the razor twice. After the first treatment there was no visible bubble algae for about 2 weeks and then it started showing up again. The second treatment completely eradicated the bubble algae and any other algae in the tank. The phosphate in the tank spiked and I had a cyano outbreak. I completed 3 50% water changes and now about 6 weeks later the tank is clear. 2 trochus snails died at the start of the second treatment. Other than that all livestock fine.
