Just block the light. Won't grow in the dark. That's why we use res covers.

Little bit of algae isn't going to hurt anything. A lot of algae should be cleaned up, as there are insects which will feed on it- and they're annoying. A whole lot of algae can present a "slip and fall" hazard- I reccommend swamp shoes and a squeegee.

Algae is just a fact of life in hydro- anywhere that solution is exposed to light, it'll grow. If you're using clear tubing for anything, it'll grow inside the tube.

Next time you're broken down, clean everything well.

You can slow algae down, but short of going to an algicide, it's tough to eliminate. If it's just a little algea on the top of your media- welcome to drip. Happens to everybody eventually.

If it's blocking your drippers, strip feed system down and peroxide it.
rhizome Reviewed by rhizome on . I got algae....... I think??? How can I get rid?? It looks like algae. For the first two weeks of flowering I was unknowingly using dirty water. I bought it from a machine that claimed RO process but when I decided to test it, two weeks after using, I found that the tds was at 170. That was dirtier than my tap in the kitchen. Anyway, does anyone know how I can get rid of it? I have a hydro drip system. Rating: 5
