First time tank
Hello, I recently got a 3 gallon 8.68x8m68x10 rimless cube tank. I want to do a neocardinia shrimp setup. I want to do a dense bush of pearl weed in the back and a carpet or foreground of mini dwarf grass and a touche of Monte Carlo. I have been doing a lot of research and getting so many different options and answers. I really want that lush carpet look I do not plan on using hardscape. I plan on using a base of fluval stratum and sand on top. I'm seeding a sponge filter in my wife's tank right now. Will I need CO2 to set this up? Also how many tissue cultures of the grass and Monte Carlo should I get? I plan on cycling it for at least a couple of months before adding shrimp, but I'm reading shrimp and co2 don't always work well. I do not have the budget either to just do a full high tech setup for CO2. My water in Texas is hard which I read is good for shrimp, but bad for plants. This will be my first more legitimate attempt at setting a tank up. Any advice, guidance, or suggestion? TYIA.
