Hi.

I've recently added about 4ml of Plant Gro to my planted 22G tank, and a few days later have noticed some sudden algae growth on glass and substrate.

Is this an unavoidable effect of plant fertiliser, and is it necessary anyway?

Do you have lots of live plants?

I'm going to assume you have live plants inthe tank, but good question Fishdanny. most likely you are running you lights to long, 8 to 10 hours is the most you want to run. If you plants are young or you just have a few plants than the adding the ferts has cause an im balance in the water. Cut you lights down to 8 hours. Also list the plants you have in the tank. You may wnat to cut down the dosing to half until the plants grow large enough or you add enough plants or have fast growing plants, to use the excess nutriants.

Thanks for replies. I have 8 plants, fairly large, in a 22G tank. Two of the plants have been spilt up and distributed around the tank.

From browsing a website, I think I have:

Egeria densa
Limnophila aquatica
Microsorium pteropus
Alternanthera reineckii

Couple of others that I can't find online.

Adding a few drops of plant feed a week. Have reduced lighting to 11 hours a day. My aquarium book recommends 13 hours for plants, should I go as low as 10 or 9?
