Green Water and MTS Boom

In my old tank I've been having a problem with Green Water for the last few weeks, and it is getting annoying now. I have been keeping the light off and changing the water on a weekly basis but this hasn't helped one bit.

I have been keeping an eye on my Ammonia/Nitrite/Nitrate and it is well within reason. I have ordered a PO4 testing kit but at this time I haven't a clue what it is. To edge on the side of caution I will be adding some PO4 remover into the canister later along with some carbon.

Also, I have just been performing a deep clean on my Eco-Complete substrate and found a massive amount of MTS. Now I did add MTS to my tank when I set it up, but I only added about 8, now I believe there are hundreds, mostly tiny ones though. I can only assume the massive boom in MTS means I have really dirty substrate, right? Eco-Complete isn't really easy to clean as most of it gets sucked up and goes down the toilet.

My filter consists of large foam pads and lots of Bio Media but I'm thinking of removing the large foam pads and replacing them with filter wool to help catch the algae. Along with some Interpet Green Away I am hoping this will do the trick?

Any suggestions...

ship me some green water for my new daphnia

green water is from too much sunlight or light and high amount of nitrate or ammonia...which i was guess is from the amount of waste that your snails has produce..with that much amount, it builds up

No direct sunlight, and rarely have the light on now.
Ammonia/Nitrite/Nitrate levels are fine.

iAndy, what is your definition of Fine for those levels?

It seems to me that if you're having a MTS population growth and green water, you have organic detritus that has accumulated. Likely, you're feeding nitrate from the decomposing matter.

I would avoid chemicals to remove the algae. There are a few options that work without chemicals, but they only serve to treat the symptoms and not the problem. Again, green water is a symptom of something else being out of whack.

That said, check out the 1-2 punch thread in the algae section of this forum. You can also try a UV sterilizer. I had to use one with great success after my lighting and CO2 outran my ferts.
