Ok. This is what i have in my tank and it has turned the water green i keep getting this on the walls nowhere else. how can i get ride of it?
i have aquasoil and i am running c02 for 8 hours a day and that is how long my lights are running too. the light is tek and it is 156 watts.
This is what is looks like.

This is either due to low phosphates or low CO2. I actually saw this type of GSA (the GSA with little grayish spots) creep up in my tank here recently, right before I pruned my tank, because some plants were beginning to block water circulation. I would first say it's a result of low CO2 levels. Not terribly low, but maybe a circulation issue. If I do skimp on PO4, the GSA seems to be the small hard green spotty type.

yeah i thing it is low water circulation. should i use the ehime spray bar..? but i really dont want to use the bar because it blows everything to the other side of the tank. because if anything i have too much co2

You didn't mention how big the tank is. If it is smaller than about 90 gallons you probably just have more light than you are providing the necessary care and feeding for. (I'm assuming the 156 watts are T5 lights with individual reflectors for each bulb.) You seem to be very sure you have plenty of CO2, but most of us felt that way just before we discovered we didn't have enough. If you are using a drop checker, and using it with 4 dKH distilled or deionized water in it, and it is very green or even a bit yellow green, you do have enough CO2, but only at the location where the drop checker is. Everywhere else is an unknown. You have to have very good water circulation throughout the whole tank to get CO2 enriched water to all of the plants.

I don't like spray bars. To get good water circulation going, a more concentrated source of flow works better. One good way to do that is to use something like this, http://www.drsfostersmith.com/produc...0&pcatid=14680, for a filter outlet. Then you can use it to set up a circular flow around the tank, perhaps point it slight upwards to get a little surface ripple, which gets more O2 into the water and that allows you to run a bit higher CO2 concentration too.

wow thanks for the help i think it was because of low circulation and i found out that my co2 hose had a stupid leak in it. so i didnt have enough co2 and bad circulation i fix both. the tank it looking much better.
thanks for the helpp!
