Alright so I have a pretty heavy planted tank and another tank with a few plants in it. They both look alright not great or even that good but the plants are alive and have been for a long time. These two tanks are very low tech (regular lighting, no co2, no fertilizer, no added nutrients). I have an old compact flouresent fixture (2x55 watts 1 bulb is daylight white and the other is actinic) that I used for my reef when it was in a 20 gallon. I want the joy of triming and tending to an aquatic garden. So here's my thoughts and anyone with some experiance can fill me in or make suggestions if they see a problem with what I'm doing. First I'm going to use a 29 gallon and use the guts from my C/F fixture to build a hood. I will be running a panguin biowheel filter rated up to 45 gallons. I want to use one of those cheap co2 systems that take the tabs every 30 days. Those things I'm pretty sure of, now I'm uncertain of substrate, fertilizer, additives, and a few medium and larger plants that would thrive under these circumstances. I'm going to use marselia sp. As my ground cover and I want that to occupy around 80 percent of the tank. So any ideas, questions or comments will be apprieciated. Thanks for reading.
