Hi, my aquarium grows green spot algae very quickly all over the glass and even on to fast growing plants such as water sprite. My aquarium is a 2 ft, ~40cm deep tank lighted with 2 x T5 super sun lights. I do CO2 fertilization, 1 bubble in 2 seconds. I've tried adding Seachem Flourish Phosphates, and nerite snails, but the GSA keep on growing. Please help!

Put more plant to cover the area that grow GSA, reduce the lighting period. Oh.. you can remove them by using 6" ruler. Also use eachem Flourish Excel.

I've tried dosing phosphates, reducing the light duration to 7 hours, and doing weekly water changes, but the GSA still grows extremely quickly. It grows on my plants too, so it would not help to shield the aquarium with plants

Just an update in case someone else faces the same problem with GSA. After looking through many forums and articles and trying various methods on my tank, I've finally managed to eradicate most of the GSA in my tank.
1) I reduced the number of hours of lighting in my tank to slightly less than 7 hours. 2) I made sure my tank doesn't get any direct sunlight. 3) I used an adaptation of Tom Barr's fertilization regime, which involved fertilizing more than the plants needs then changing 50% of the water at the end of the week, plus dosed extra phosphates. 4) Some of the plants grew large and overshadowed the light, which gave time for the other plants to be established, so that they could outcompete the algae even after I trimmed back the plants. I still get a tiny bit of GSA on the glass, which I clean off every week, but now my tank is so much better without the GSA, which previously grew not only on the glass, but also on the plants. |

Found some info on this topic.
I remb asking the boss of a LFS and he told me do more water change. Bio load and nutrients are a major cause. I increase WC regiment and found e GSA growth to slow down. What Causes Algae Overgrowth? Like any plant life, algae thrive on three basic necessities: water, sunlight and nutrients. If an excess of any are available, algae will grow like wildfire, just like weeds growing in a garden. Obviously you can't do without water in your aquarium, but you can control the amount of light and nutrients are in the water. Here are the common reasons for algae overgrowth. Lights left on too long Aquarium in a location with direct sunlight Overfeeding the fish water changes Using water with high nutrients Avoiding Algae Overgrowth Knowing the causes of algae overgrowth is the first half of the battle. Here is what you should do to avoid overgrowth. Reduce Lighting – Don't place the tank where there is direct sunlight, for even part of the day. Sunlight can, and will, promote algae growth. When using artificial light make sure it is not stronger than necessary, and is not on more than about eight hours each day. To ensure that, use a timer to turn the lights on and off each day. Feed Less – The majority of owners overfeed their fish, which increases the phosphate levels in the water. Feed small portions and watch the fish eat. If all the food isn't eaten in five minutes, you are feeding too much. Always remove any uneaten food promptly. Water Changes – The single most important way to avoid algae is to perform regular water changes. Change ten to fifteen percent of your aquarium water every week to keep nutrients in the water low. Know Your Water – Test your water source. If it is high in phosphates, you should consider using phosphate removers or find another water source. It's wise to also test for nitrates, as some water sources have elevated nitrates. It doesn't do much good to change the water if you are adding nutrients! Clean It Up - If you see algae beginning to grow on the glass, rocks, or other hard surfaces of the tank, remove it. Scrape the glass, remove rocks and scrub them, and vacuum the gravel when you perform water changes. Keep Live Plants – Live plants will use many of the nutrients that algae thrive upon. Fewer nutrients means there is less fuel for algae overgrowth. Keep Algae Eating Fish – Keeping Siamese Flying Fox, Otocinclus, or even the common Plecostomus, will help reduce some of the algae in the tank. http://freshaquarium.about.com/od/al...ttackalgae.htm |

tom Barr method is the best so far in my tank, it works well , you can follow this method on fertilisation and make sure you plant alot too, and with proper lighting and co2 it should be fine. The only thing i do different from Tom is i change 90% water instead of 50%, and i have min algae problems or not at all.
