Planting in a sandy alkaline tank
I was recommended to post my question here and am hoping someone will be able to help. I currently have a 120l tank housing N. Brevis shell dwellers (not likely to eat the plants) with a 2226 Eheim filter, 2x 2ft T5 lighting connectors (light tubes can be changed), a coral sand substrate with a rocky background. I would like to put some plants in, though am not sure what I can go with? The pH of the water is around 8 with a temperature 24-26 degrees celcius. Would I need to change / supplement my substrate and/or add CO2, or are there plants out there that would fare well in my current tank conditions?
I haven't kept plants in a tank before so any advice will be muchly appreciated!
