I have a 6' 125 gallon tank was thinking of adding some plants to help filtrate a bit more. Are there any out there that will work well and don't require an expensive light to grow? Currently have carib sand in there with a good bit of lava rocks. I'm moving at the end of the month and switching over to texas holey rock though. I will also add an fx6 so the total filtration will end up being an fx6 and a fx5. Any other info you guys need lemme know
