Re: AlgaeFix warning for guppies
I'm strictly "old school" when it comes to putting chemicals into my Guppy tanks. I've never done it. I believe there are always natural things that can be done to deal with any tank problem.
My tanks are very simple, so if I have a problem, which is pretty rare, the problem is easily fixed. Usually, it takes a large water change of at least 50 percent to get things back to normal.
Algae is a sign of a healthy tank. Wheather it's visible or not, depends on tank conditions, but healthy tanks have it. I keep large tanks and aside from a little on a few of the plant leaves, there isn't much.
The reason algae occurs is you have too many fish and not enough plants, so there's a lot of nutrients available. I have a lot of snails and they help keep the algae under control. Fast growing plants like Hygrophila, Pennywort, Hornwort, Water sprite, Water wisteria and Anacharis (needs strong light) all require a lot of nutrition, so plant these. Large, weekly water changes of a minimum of 50 percent will also help control the algae.
The natural remedies don't work overnight like the Gluteraldehyde products, but they won't kill the algae and create more food for the next algae bloom, just take the food away and create an enviroment where the algae grows very slowly and eventually shrinks.
