Green dots on plants and tank

[zeek_fon]

Dear all,

May I know if those green dots that are found on tank wall and plants are algae?? I got small numbers of plants with green dots and my tank wall have it too.

Is that due to high intensity of lighting or poor circulation of water or not enough co2??

Hope to hear some advise from you all.

Thanks for your time.

Green Spot algea. Can manually scrap it off the tank wall. For plants guess you have to cut off those affected one.

Thanks bro Henree.

Btw, what causes green spot algae?? Hope to eleminate the root of trouble.

Thanks.

how long did you turn on the light per day? and what plants you're keeping?

If your tank mostly is most than put some fast growing plant like riccia, rotala sp green, afican frogbit and etc to reduce algae problem.

scrape it all off and do a water change
then reduce your daily lighting and increase co2 levels
i do that whenever any of my tanks gets hit by gsa
and they don't seem to come back significantly afterwards

Adding to lee1224's suggestion. You may also use UV lamps to 'clean' the water. Purhase one that has a higher capacity if not it would defeat its purposes.

For my case, most of the time, what I do is that I throw in a bit more KH2PO4, this keeps the GSA in check.

Normally GSA will grow on slower growing plants, that being nanas, etc. Lowering your lighting and throwing in more fast growing plants will definitely help you.

Of course having strong lighting for a tank with mainly slower growing plants such as nanas or ferns will give you a tank of GSA.

And of course, do a weekly water-change/maintenance would be good.

I think poor flowrate and water circulation in the tank will cause the GSA. I let my nana flow on the surface direct under light.. it grow new leave without GSA problem and growing rate faster.

I use ADA liquid fertilizer mixed with EasyLife liquid fertilizer.

Not too sure about the flowrate/circulation issue but maybe that can be the cause perhaps.

However, naturally, if you let anything grow above the surface without contact with little/no contact with water, you don't get algae of any form.

I think strong light is the main cause of green spot algae. When fewer plants are planted like in a rock scape, cannot take all the nutrients, so algae grows on glass or hardware.
