I currently have a 75 gallon tank of african cichlids with an eheim 2217 canister filter, 2 powerheads for added circulation, external heater, lots of holy limestone for decor. The substrate is 40lbs caribsea eco-complete cichlid sand and 40lbs carbisea arga-alive crushed coral. Know of any plants that would grow in this? Suggestions of how to make changes without draining the tank to remove the entire substrate? I do know some about planted tanks i have a 29 gallon tank fully planted with co2 and the works but to create that tank i had to drain the tank n start it over compeltly and i would like to grow some plants in the 75 but not near like my small tank. oh btw each tank has 4 t5 bulbs the length of the tank so plenty of light for majority of plants. Give me some feedback guys thanks in advance!
