help with hornwort and anacharis

[fishdud]

Im having problems growing these two plants. When I first got em, they grew like crazy to the top of my tank. Now even since I cut em in half to trim em, they haven't been doing good and not growing all that much.

 

[jetajockey]

are you dosing ferts at all?

 

[fishdud]

Flourish comprehensive

 

[jetajockey]

how about dosing NPK?

 

[fishdud]

Dumb question but what's that?:/

 

[jetajockey]

NPK are the macronutrients. Nitrogen, Phosphorus, Potassium, seachem comp has separate bottles of that stuff.

Usually, fish waste should maintain a level of nitrogen (nitrates) in the tank, so if you are testing positive for nitrates you are fine.

Tap water often has phosphates and different micronutrients in it, so sometimes a big water change will replenish any deficiencies and get growth going again, otherwise consider dosing the macronutrients (NPK) along with the micronutrients (flourish comp)

Oh yeah. And I have the same plants in my ten gallon with stock lighting and they seem to be doing better. Even the Java moss won't grown in my 36 gallon.
