why do all my plants die? info in desc
first tank: 1-4, second tank: 5-8
in my first tank, my jungle val keeps melting and I have no idea why. I had hair grass in there at one point and it was thriving for a few days, then suddenly all died within maybe a week. the Amazon swords seem to be the only thing growing more leaves for some reason. also, in pic 3 shows the roots of my pothos that is on top of the tank- is that brown algae on them or something? or are they dying too? the leaves look flawless up top but the roots look like crap so I cant explain that either. there are atleast some sweet potato roots in the back that are doing good.
in my second tank, I also had hair grass in there and that died too, though it didn't thrive at all. it died rather quickly. I then put that Java fern in there and it was doing good until I saw it had galls. I know you cant really get rid of galls but I removed the leaves that had it and it's still dying (pic 7), so I'm not too surprised. so far I have some rotala in there (it was red but now growing green), some Java moss, a mysterious blade of grass that I have no idea what it is, and some mysterious leaves I cant ID either. those are all thriving just fine but I really feel like I need better plants for my corys. there is also a pothos on top and some sweet potato roots that are doing amazing.
I forgot to mention, I did have a ton of frogbit in the first tank but it all died a long time ago and now it's just barely coming back. it seems like some good leaves will grow and then die shortly after because of, what I think is brown algae, on the roots? I did put a little bit in the second tank too but they just multiply SO slowly.
my problem is I do the same exact thing for both these tanks. tank one is actually about a month older than the other, they are about 3 and 2 months old. I dose api leaf zone in both of them once a week, there is some cheap root tabs in the sand (is that the problem?), and the lighting seems to be good. I bought some cheap Amazon lights but they had good reviews and I have been using them ever since. so how come my first tank is doing so horrible compared to the other one??
