  1. Default Floating plant for high light tank to help reduce algae?

    0 Not allowed!
    I've got a large 4x65w CF light that I used to use on my 110g tall.

    I sold the 110g tall a long time ago and put the light on my 30g planted cherry shrimp tank but only have 2 of the lights turned on and for only 7 hours a day.

    I'm getting some algae issues obviously as 130w/30g=4.33w/g which is considered high. a tiny amount of Black brush, some green spot on the glass, some green hair, brown/blackish film on leaves.....all in all not the best looking.

    I have no fish, don't do any ferts, no c02 and have no time or will to get back into all that.... I also don't really want to spend the money on a new light more suited for my tank so.....

    I was thinking maybe there's a high light floating plant that might help shade out some of the excess light?

    Amazon Frogbit does wonders. Also, Riccia fluitans can be used as a floating plant.

    There is a dwarf water lettuce that will grow like crazy if you can find the stuff. I havnt seen it at my lfs for years. There is also azolla which will do it for sure.

    Duckweed! But remember, it's like herpies! Once you introduce it to a tank it's real hard to get rid of.

    Oops I forgot.

    I used to have amazon frogbit in my 110g tall that did fine, and it was in my low quality 29g beginner tank and for some reason was the best looking plant ever.

    But the frogbit died quickly when it went into the 30g tank... so most likely I'm not going to try that again.

    current 30g when I set it up. (doesn't look like this anymore :( )

    Salvinia is a great nutrient sponge. I have it in my tropical tank. Have to thin is about once a month... Takes is about that long to cover the whole surface of the 2ft wide tank. Much neater plant than most floaters. Doesn't have ridiculously long roots and it very easy to remove.
