I have the following plants:
8 cryptocorne lucens
3 Amazon sword
5 baccopa
1 anubias barteri
1 Mayaca vandeli
2 dwarf tiger Lilly
Several Java fern and Java fern wendelov
I dose easy green twice per week and add extra potassium twice per week also. My plants are not taking off like I expected.
Some of the plants are happy (Mayaca, anubias, Tiger Lilly) and others don’t appear to be (Java fern, baccopa, cryptocorne, Amazon swords). I planted four Amazon swords a month ago and they haven’t gotten bigger then when I planted them. I did lower my lights to 50% brightness to help cut down on algae but they still run for 12 hours per day. Should the lights be brighter? More fertilizer?
I test water weekly and am stable at 7.4ph, 0 ammonia, 0 nitrite, and I do 20% water change when nitrates go over 40ppm. I recently tested GH and KH and they came back fine. Same with phosphorous.
