Flourish Excel And Light Level

[montyII]

Anyone know if Flourish Excel is a good enough source of carbon to allow more than 2wpg of light? I've read that you shouldn't go over 2wpg without CO2.

I'm currently running 1.7wpg (Life-GloII and Aqua-Glo) in my 35gal, no CO2 tank. I've had a bit of a problem with hair algae and plants not doing too well (related I know). I thought the Excel would help with both problems, and figured I'd up the light a bit if it all works out to further boost the plants.

Sombody? Anybody?

First off, I would say don`t go beyond 2WPG because the work load will start to become a burden. At 2WPG you will need diffused pressurised CO2, although you may get away with using a few Nutrafin canisters (couldn`t say how many, I don`t use them) provided you manage them properly.

Plants will take Carbon more readily from a diffused gas rather than from the organic Carbon in Excel. At 2WPG your plants will not be able to get the necessary amount of Carbon , their growth will stunt and algae will appear in all its splendour.

Ok, ta for that, Dave. DIY CO2 does look very messy and fiddly... might just keep everything as simple as possible for now (until I get bored and decide my credit card needs another workout.... pressureised CO2, eh...?)
