Help for my plants, not harming my axolotl in process

[AxolotlGooner]

Hi there.

My axolotl, Mixcoatl, has a fairly large tank all to himself with lots of places to hide and relax. His tank is very bad with algae growth however. Being unable to put plecs into the tank due to Mixcoatl wanting to eat them all, I have resorted to plants to counter act the algae growth.

A floating plant that has done wonders for this battle against algae in his tank is Salvinia. Due to it being a floating plant that spreads out a lot! It blocks quite a lot of light getting into his tank and along with absorbing the nitrates and nitrites at the same time it truly is making life difficult for the algae.

issue i have though is that this plant does need some form of fertiliser/food to keep it vibrant and well to make sure it continues to fight the algae. I can’t seem to find any where any info as to whether I can put certain plant fertiliser/food into his tank to help the plants as well as not harming Mixcoatl in the process. Can anyone help?

Well, if Salvinia is efficient against algae, that's good news. It also absorbs directly ammonium.
If your Salvinia seems to stop growing, you can throw out a part of it.
Else everything is all right.
I wouldn't add fertilizers anyway. Axolotl poo should be enough

I would agree with the above statement that axolotl poop should be enough. To address the algae problem more directly, however, is there any way that the light that hits the tank can be reduced by moving the tank and/or using a curtain-like device? Axolotls really don't like a lot of light, and if there's enough light for an algae problem, there's probably too much for your axolotl.
