My tank specs:
29 gallon
Nova Extreme 2x24W T5HO
Eco-complete
No ferts or CO2
Heavily stocked with fish

I have a few stem plants (rotala, ludwigia, hygro) that are growing well, but slowly. I have rather large bunch of anacharis that is growing much faster than the other plants. Since I don't use CO2 or fertilize, would removing a good amount of the anacharis cause the other plants to grow faster?

I don't ever plan on having CO2. Would I still benefit from using dry ferts?

Trimming reduces the demand by the fast grower. Ferts. always help even w/o CO2. Less is needed but the plants still benefit.

Anacharis is one of the most effective nutrient hogs in the biz. So I would think that by keeping it in check you could allow other plants to have a better chance of taking up nutrients as well.

Just make sure that you dispose of extra Anacharis appropriately, and not dumping it into local waterways. it is considered a noxious weed in many states and could take over.

No, if the other plants are not limited(eg you not adding enough for them).

Light
CO2
Nutrients

If those are lacking, them other species will compete amongst one another.
Egeria is really good at low levels of CO2, nutrients and light.

That is what makes it such a good aquatic weed.
