Fertilizers for a non-C02 tank

[Francesco]

I have changed the water 2 days ago and I haven't dosed the fertilizers yet. Maybe, using Excel, the 1,5 wpg aren't enough. I could add another T5 to bring the wpg up to 2,3. What do you thing? Maybe there has been too much excel/fertilisers and too little lighting.
here is a picture of the algae I see growing on some little stones all over the tank: Attachment 2920

Hello

As I understand it Seachem Phosphorus is dissolved KH2PO4. I guess if Easy Life products are easily available in Italy you could use Easy Life Fosfo and maybe Nitro too. They keep the ingridients a secret but I'd guess it's the same thing

Hi,

I think the Easy-Life Fosfo probably just fine, though I do not like people who are afraid to list chemicals.

I can based on the label assure you it is not KH₂PO₄ or K₂HPO₄ or anything with Potassium.

My best guess based on the label is Diphosphorus Pentoxide, P₂O₅, a common desiccant.
