Hi, this is my first attempt at a planted tank. I am no beginner, but new to planted tanks. I have a average light, and less-than-desirable substrate. Substrate is black Diamond sand. I have been warned it’s not great, but I decided to take the chance. I got a few Anubias and Java Fern which I stuck to lava rock and driftwood, and then I got a few Vallisneria, which was bought as Jungle Val, but I’m starting to suspect it’s Vallisneria Spiralis. I also got some kind of Rotala. I root tabs as per the plants needs. Do I need to put the tabs in now? The tank is 90g with 8’ square bottom, hence my decision of Vallisneria. Hope you like it!
