New aquarium owner here. I have a ten gallon with gravel substrate and only a single betta fish. Ammonia was 0.25, nitrite was 0, and nitrates were 40.
About 4-5 weeks ago I ordered a Vallisneria, red flame sword, and a pogostemon stellatus “PG”. They were all healthy looking initially but over the course of the last few weeks, the vallisneria and PG both are looking terrible. Both seem to be melting away. The Vallisneria has two runners but even those are starting to melt. Both plants appear very faded in color. I’d been leaving the lights on the aquarium hood for about 8-9 hours per day. The red flame sword is growing new leaves every week or so but have noticed that some older leaves are starting to have yellow or rust colored spots. Is this normal?
The crypt lutea I also got around the same time seems to be fading better as it has some new leaves and appears to still be a vibrant green.
I have root tabs which I’d used once and have dosed Easy Green about 3 times since I got them.
What am I doing wrong? I feel very discouraged now and I’d just ordered three more plants last week. I hope they all make it!
