With trout and algae problems, look into using Phycomycin or Green Clean Pro. These are called Sodium carbonate peroxyhydrate - basically hydrogen peroxide as active ingredient. Pak 27 is what I use and is the same product but it is not readily available as retail. Green Clean Pro is made in China but Phycomycin and Pak27 are made in Texas - Solvay Chemical. Sodium percarbonate acts by oxidizing the skin on the algae while releasing oxygen. It is very safe for use with chemically sensitive invertebrates and fish including trout. It is best used on FA when it is very small and in early growth stages, not when FA is tall, long, and stringy unless you use a lot of product. Phycomycin in available at most Cygnet Enterprises and some other retailers. Green Clean Pro is the most commonly available form of sodium peroxyhydrate.
