I'm having problem with my 75 gallon tank. Since switching from my 60 6 months ago the plants aren't doing so hot, I have all low light plants a 48" Fluval plant led (1 gen only 5,200K), sand in my substrate with a bit of osmocote plus in there and pressurized co2 setup a couple of days ago. Do you guy think I should change the substrate to something like Eco-complete or Seachem Flourite? Also should I add to my lighting or go with a complete new unit and if so what? I also looking at going with a quad T5 system or adding a couple of goose-neck lights par38 6500K or add a finnex planted plus led to the one I have. Any suggestions would be great
Thanks
