Hey guys i am hoping to get some advise. Ive been working on a planted tank since about feb. Since then ive upped my lights to 2xt5ho and i am running pressurized c02 at about 3bps. The only ferts i really use is flourish every other day or so..... plants seem to be doing ok, but id like to try some better ferts to keep them happy. Keep in mind im not looking to spend a ton of money. Let me know what my options are. I see a lot of this IE dosing. can someone explain that, thanks again everyone....
