So I have a 29 gal I used to have planted, but the plants eventually all died off. I want to replant it, but I want to make sure it's done right this time. My water is soft, so what are some cheaper, hardy softwater plants? The gravel is 20 lbs of Seachem's Flourite mixed with 10 lbs of regular gravel. My light is a 24 inch Flora Sun Max Plant Growth bulb. I also have liquid plant fertilizer I can use weekly. The temp is about 78F. Any suggestions? Thanks!
