20g high low light plants not doing well

Hey all, I would appreciate some help with my planted tank. It has been established for about five weeks. Since then the plants have not been doing well.

The tank is a 20gallon high. The plants I have are java fern, amazon sword, cryptocoryne lucent, and an anachris. The only plant that is doing okay is the crptocoryne, yet it still is developing yellow/brownish spots. The java fern is black. The amazon sword leafs look thin and pale. The anachris is fine but it is a new addition. I previously had hornwort in the tank but that has since died.

For substrate I have caribsea eco-complete. For lighting I have the nicrew led and a 15w T8 TropicSun 5500k feature. The lights are on for a 12 hour period. I am also dosing Flourish Excel and aquavitro envy.

Any help would be greatly appreciated!

Hi

This is a good article to read about setting up a low tech tank.

How to Setup a Low-tech Planted Tank: Planted Aquarium Guide | Bits and pieces of my digital life


As long as you fertilize the water column properly you do not need to "dirt" the tank or use root tabs so no need to worry about that. The article states that you should not do weekly water changes as this "may" trigger some sorts of algae. I don't follow that and do a 50% water change once a week and have no problems with algae.

Another thing is plant mass. You want to basically cover at least 80% of the floor with plants, fast growing preferred. Last thing is patience, start things going on the right track and all will be fine.

What kind of fish you have there btw?
