  1. Exclamation Algae issue? Help

    0 Not allowed!
    Hey guys, this is my first post here on Aquatic Community!

    I recently upgraded to a 55 gallon planted tank about a month ago with a 48" Aquatic Life T5 HO fixture (110 watts in total I believe). The lamp has worked great and my plants have been growing like crazy, however, I also recently ran into an algae problem and not sure how to handle it.

    I apologize for the poor quality pictures, I tried to point out my concern in each picture:

    The driftwood has this light green algae growing on it and a bit underneath the java moss, the water sprite has a brownish precipitate on its leaves, and theres a little patch of this green algae in one spot of my tank.

    I'm not sure whats causing this or how to deal with it, but I regularly use Flourish Excel and Micro nutrients. Have a C-360 and sponge filter going as well. I've leave the lights on from usually 9am-9pm everyday, which may be too much light?

    Anyways, any help would be greatly appreciated!

    Algae issues are almost always caused by a imbalance between light and nutrients.

    I would suggest to start by cutting back a bit on lighting. 12 hours is very long, even more so when you have a good lighting like you do. I would try cutting back the lighting to 8 hours for a week or two and see how much of difference this makes. This should not harm your pants

    Does this green algae wipe of very easily, almost in small chunks ?

    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Welcome to the forum. I'll second Cliff here and say that your light might be the problem. I run mine about 6 hours and this seems to keep the algae at bay. It isn't all gone, but it isn't spreading either and I don't mind what I have already. One thing I think Cliff is eluding to in his final question is proper identification of the type of algae will help you understand how to combat it. Let us know what characteristics this algae has and we can help tailor a defense.

    Yeah! I actually just tried wiping it off and it comes off extremely easily. I can literally scrape it all off with just my nail.

    I'll reduce the lighting for sure!

    Let me know what you guys think!

    That sounds like it might be cyanobacteria. Does it spread really fast? You clean it and in just a few days it's right back where it was? I've had this issue in my tank. That stuff is tough to get rid of. Just keep your lights off longer, keep up with your water changes to keep nitrates down and clean that stuff off religiously. If you see it, remove it. Doesn't take long for it to get out of control. Hopefully you'll overwhelm it and it'll go away.

    Cyano rubs off really easily and you can syphon it away. It's not a traditional algae as such. If it is indeed this it will look slightly blueish green when you get it out. For that I'd say:
    1. syphon away what you can
    2. Feed the fish a decent meal
    3. Tape some binbags or something all over the tank so no light gets in
    4. Switch off the lights and keep them off for 72 hours
    5. Syphon away what you see in dead algae and do a big water change.

    As to algae in general... if you can afford it get a nitrate and a sensitive phosphate kit and start weekly measures. Get some dry salts, k2po4 and KNO3 and distilled water. Mix a solution so that 1ml of kno3 solution raises your level by 1 ppm and for k2po4 so that 1ml raises the level 0.1ppm Try to balance the tank so you always have a nitrate phosphate ration of 10:1 and not get your nitrates over 20ppm.
