Clearly you haven't seen this thread:
Ive seen it thank you..
I still think a properly done co2 tank looks better than most of those.. just ur personal opinion
Like i said in my post.. you can't have a lot of really high demanding plants and get the same color or growth from low tech..
Sure some of those low tech's look great, but the best ones are filled with easy growing plants that don't require a whole lot.. Most of them dosing excel have a much better look. Co2 just rids me of the headache of algae problems as it can come up quick in low tech
According to Tom Barr's reports most Co2 tanks can grow 15 times faster than no co2, which is what i prefer as well
