Alrighty then. So I have a 75 gal with 3 baby rb's and want to get more into plants. I have a big piece of arched driftwood with two amazon swords to cover the archway so the fish can hide behind and some other small single skinny looking plants couldn't tell you what they are the lfs guy said they'd be fine in a low light tank. Which brings me to my set up. All i have is regular small sized gravel and two 40watt t12 6500k aquarium bulbs from the hardware store. My kh is way off, like 13dkh so very hard water. I've got like 4 of the flourish tabs in the gravel along with using regular kents liquid plant fertilizer like twice a week. Well the long skinny plants are ok, sorry i don't have the name i'll go back an see what they are. But the swords aren't doing so hot. I would love to do some more plants but also keep it low tech. What plants should i consider that could possibly survive for me and also any other ideas as far as fertilizer or possibly adding some other plant substrate mixed in with the gravel? This is my first time ever attempting this so bear with me. Thanks for any advice!
