When I first got the plant, I had just a basic light that came with the aquarium. It's a 30 gallon. Now I have 2 lights, DIY CO2, black sand substrate. It's an invert tank. I have lots of plants in it now and they're all growing pretty well. Hopefully my Red Rubin will split soon.
I didn't get root tabs because I saw that they have various metals in them and I'm afraid that they'll affect my inverts. I was looking at Seachem Root Tabs. Is the copper and various other metal content enough to hurt the shrimp and snails?
I bought a bulb from Lowes for plants and installed it on a 1 light, then I have another light that came with a 55 gallon that I just bought and put it on the tank too. It's 2 different types of light and I'm not sure about the WPG (don't know how to figure it up).
check out the bulbs. or figure out how long they are. are they florescent bulbs? root tabs are in the gravel the roots use it and unless you pull it out it doesnt get into the water column. a lot of people use trace ferts in the tank with no problem.
One bulb is 24" the other is the size smaller 18"? It's for a 20 gallon. I do dose with Seachem Flourish Excel, 1 capful a day. The bulbs are fluorescent.
