Im a huge fan of hydroguard. I love that stuff.. My hydro guy told me the Govt is forcing them to change from liquid to powder form. Something about proper use of chemicals.

I've had a few algae problems in my E&F and if you use the proper amount of hydroguard, it takes care of it every time.

peace
