Thank you for your opinion. I use Sera Florplant. There should be all, but it is not as good as PMDD probably. It would be better to mix it by myself. Next step. I know that my phosphates should not be zero. But I am not sure that P is not there. I have only test for PO4. My tap water has 0,25 mg/l PO4(about 1 mg/galon?) and I change 1/5 - 1/4 every week. Tap water also has NO3 25 mg/l (100mg/galon?). I also add 15 fish (small Microrasbora Galaxy). Light is 56W together (1x28W Day and 1x 28W Natura, 12 hours a day). My mistake. I am sorry.
I have a lot of plants - about 15x Limnophila, 18x Rotala, 4x Anubias, some Valisneria Spiralis, 3x Pogostemon helferi, 3x Cryptocotyne ...

As I wrote - I have not problems with plants, but with one kind of algae from pictures. I am not able to identify it, so it is very bad to fight with it. Could someone tell me exactly what kind of algae/BGA it is? Here is another photo from today.

Thank you.
