i have 30 gallon fowlr and i cleaned up my substrate rocks and such and 2 days later i have a ton of green algae growing on the substrate rocks. and all over my live rocks the snails eat it but they can't take care of that much. In 2 days there's a ton of it what is causing this.

A combination of lots of light and plant friendly nutrients in the water. How many hours per day is your light on?

I had the same problem, algae built up 2 days after cleaning it.
I'm almost 100% sure it's a light problem.
If you're using the light bulb that came with the tank, it's probably not a good one. I changed my light to a power-glo bulb and put it on a timer so it's on only 9 hours per day and never have an algae problem now. Makes the tank much more enjoyable!

You could also use the aqua-glo bulb which gives off a more natural light from my understanding. The power-glo give a hint of purple look to it (which I like). It's all preference really.
And these bulbs will make the colours of your fish more vibrant.

Good luck, keep us posted!

You really don't need more than 4 - 6 hours for your tank since you have no coral, The rock will grow slower and you will not have to deal with the algae that's happening unless you wantcoral and that takes a good light to produce a full spetrum of light that coral need to grow.I would do lighting when you are home and at least a few hours before you arrive homeso that fish are alert to your presents.
