Hey everyone. I have a 29 gallon aquatic setup. Bare bottom, with java fern, anubias nana, anacharis, and some salvinia and duckweed. I originally set this tank up a long time ago because I was hoping to get some adult newts, but it didn't pan out. I don't see much growth in my plants besides the anubias and java fern (it seems they just need to be wet to grow), but a lot of my plants are looking white. Even my duckweed is dying! I have been doing 25% weekly water changes and adding 3 frozen brine shrimp cubes for ammonia. I have full spec lighting LED and water temp is 69F by the way. What can I do to keep plants alive? Thanks.
