Hey all. I really love planted tanks. However, i cant do CO2. Bit expensive for my current prices etc. I run a 20g w/ shrimp. They have an assortment of plants. Currently working on baby tears. (Snipped some tops, and snipped roots) Ludwigia Repens, maybe an amazon sword, etc. Currently just a gravel tank. (Dirt in the future, eventually way out CO2 maybe.) I have a gro-lite bulb, seems to make all the plants nice and green. What can I do for dosing? I have a bottle of Seachem Flourish I've dosed 1mL sunday(or sat) and another 1mL wednesday. (Probably twice a week from now on) I use a syringe for it, feel super cool doing it that way. Should I be adding CO2? --- I want to grow my plants more. I feel this is a good idea. I added flourish to get the nutrients into the plants a bit be/f I start dosing w/ liquid Carbon... So. Should I add CO2? I'm running an Aquaclear 50 (((with carbon))) (Sponge on intake, set on low) Will this provide enough water agitation/oxygen for my shrimp? I'm debating on adding my sponge filter (40) on a low bubble setting maybe?? Its been in a 40g breeder w/ my cichlids getting a bacteria colony. Not sure if I'm missing anything. Lemme know. =] Im a newbie.
