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!
