Algae control with Physan and bleach

[terryros]

There are a variety of opinions about controlling algae growth with s/h. Physan 20 can work to treat and may be able to control growth when used on an intermittent basis. Other opinions talk about periodic use of small amounts of bleach in a flush solution for control.

I recently got an opinion that mixing Physan 20 in with fertilizer might create some substances that might not be the best for growth. I had been mixing a small amount of Physan 20 with my fertilizer solution.

Searching the forum on this topic is a little chaotic so I thought this might collect opinions in one place. Maybe there is truth out there and maybe only anecdotal opinions.
