I've been doing more reading and re-organizing and have gotten to where when we move later this year I'll only have 2 tanks to move, my saltwater one and my 20 gallon(now housing both of my bettas) On my old goldfish tank(29 gallons) I had a 65 watt PC light. If I'm JUST using excel(and dry ferts), would that be too much light? I don't have the money to do pressurised CO2, and I don't know if I have the technical know-how to do DIY properly. If it is, I'll just stick to buying a T5 for the planted tank. Thank you
