I have the green dot algae problem since the first month of planting my tank.
If I dont clean the tank glass every week during water changes the green dot algae which is very annoying gets worse. It covers a big part of my aquarium glass. The strange part is that it appears only on the front glass and a few of the plant leaves (slow n fast growing).
I had a hair algae problem in the beginning but that disappeared after a month. My tank is 18 gallons, T5*24 W and T8 * 10W for 10 hours daily on timer. I have an external Tetratec 700 filter and Hailea chiller with external Eheim powerhead, tank temperature is 24 degrees (we're in spring season and the temperature outside is 32-34 degrees, in summer it goes up to 36-42 degrees on very hot days). My fish and plants look good no sudden diseases or deaths, I have 3 SAE's, Guppies, Henkle's rasbora's, nerite and pond snails. I have never used any algae killing chemicals in this tank since I set it up since 12/2011.

I take good care of my tank be it water changes RO every weekend, CO2 (solenoid regulator and atomizer), the plants are growing fast with vibrant colors, clean external filter every 3 months, dozing fertilizers, feed less n good quality food to my fish, snails as cleaners, etc.

I'm doing my best but this algae keeps on coming back its very annoying. I added 4 nerite snails who are doing a good job but 2 out of 4 died eventually may be of oldage. May be I'm missing something ? Guys can anyone help me understand what is exactly going on with this tank ? :confused:
 
To prevent GSA (green spot algae) keep stable CO2 levels, dose NPK regularly and improve the water circulation throughout the tank for better nutrient transport. Keep slow growing plants in places where they will get less light.
