    Hi, arround a month back, I have started a 4x2x2 tank with 2 150watt MH.
    Details are,

    Peat+Laterite Base topped with River Sand
    2x150watt 8000K HM (Started with 6 Hrs and increased it to 9 hrs per day)
    2217 for Filteration
    Pressurized CO2 (Started with 3BPS, Drop checker showing me Dark Green Color)
    EI Dosing (KNO3, K2SO4, HK2PO4 For Macro. Along with Micro I have started dosing Iron too)
    Weekly 70% water change

    But suddenly within week the tank is full of Hair Algae. It's brown In color and covered the glosso bed completely.

    I assumed, too much of Blue Spectrum along with heavy Iron dosing is one of the reason. So I changed the Bulbs to 4200K and 6500K. Stopped dosing Extra Iron. As the tank is fishless, I am planning to increase the CO2 to 5BPS.

    I have excel but didn't dose as I saw HM burns out on Excel Overdose. Will post a picture shortly.

    Please help me to remove this menace.

    Thanks in advance.

    Hi,

    How far away are the MH from the water surface? 10-12 inches is a good start as they are strong lights.

    Have you cleaned your filters recently? Could they be dirty?

    Your issue may be c02, as a dark green color is not as good as light green or yellowish. Are you using a 4 or 5 degree kh solution in your checker?

    Since you have no fish (yet) try increasing your rate some and monitor the plants.

    5 bps doesn't sound like a lot for a tank of you size. Is it 180 gals?

    Also, a 70% wc is a lot. You should dose more to make up for that.

    What do you mean by this? What is HM?

    I use excel but only the recommended amount and only on the WC day.

    Here is an algae link that is very helpful:

    Aquarium Algae ID (updated 16th Spet '08)

    Also, a larger tank needs a stronger current/flow to distribute c02 and other nutrients around the tank. Do you have an extra powerhead to help with this?

    I have the same size tank as yours (4x2x2 180 gals) and I use two extra Koralia IV models when the c02 is on to provide more current and flow.

    Hope this helps.

    Thanks for the reply.

    MH are installed 1 feet away from the water surface.

    I am using a brand new 2217, and I cleaned it 1 week before. So there is no chance they will be dirty.

    I am using my tank water only for the kH solution. This is 11 DKH (I know it is too high).

    I increased the CO2 to 5BPS. Now it Drop checker turned into Lemmon Yellow now. But this is a killer amount for any fishes. I just put one angel just to see the result and it started gasping immidiately.

    I meant hemianthus micranthemoides.

    I will increase the water current. Tomorrow I will install another power head to increase the circulation.
