Liquid carbon should at least be used with them if you don't want to do CO2.
Dirted tanks need special care in the first weeks. If you don't understand about their releasing excess nutrients and gas in the first week people can run into problems. Lighting has to be kept to 6 hours and certain plants that absorb a lot of nutrients need to be used for a while. Dirted tanks can often have algae issues in the beginning and it helps to have experience in keeping planted tanks before moving into dirted tanks. They can be very messy if you constantly move plants around.
Thank you very much for the advice and how is eco complete different from seachem fluorite and floramax?
