I think your high light, fertilizer dosed tanks without added co2 are some bizarre exception, not the rule.
....daily full doses of excel...
sounds very much like the tank in my above pic.except I did use excel.I run a 5wpg tank with ferts but no CO2 or Excel. I have only minimal algae on the glass and good plant growth. I don't know for sure why this tank works so well for me because I have plenty of problems in other tanks. I think it's a combo of of the type of plants (easy, fast-growing stem plants), the red flint substrate with no gravel siphoning and the strong lighting.

I don't think we're trying to offer false encouragement. I just think people should experiment and try to find something that works for them. Figuring something out on your own without following a rule book is fun.![]()
If there's a rule book for planted tanks, I'd love to get a copy.
jh:I still insist that algae free, high light tanks, with no added carbon (co2 or excel) are the exception.
I welcome anybody to try it, cause if it works w/o co2, great, but 99% of the time if you run a high light tank with no co2, you'll have algae issues. I'm not contesting y'alls success, but rather not wanting to falsely encourage other people.
