Ha! There is no intervention for this addiction (other than the hubby saying he won't move out the couch in the family room)
Only one tank has CO2, the 40g. All the rest just get dosed with Seachem products and that's it.
could you tell me what seachem products you use? i use the flourish every 3rd day (with water change) and exel 1x per week. i have a 45 gal tank with 48 watts of light. my tank is only 12" deep but it's 56" long. (it's a coffee table tank) i have the usual low light plants and they are doing well but your plants look great. maybe i'm missing something?
