do i need co2
Hi, i have a 29 gallon with 2 amazon swords, a bunch of dwarf sag, wisteria, and compacta.
I have eco complete substrate
48 watt nova extreme light raised on legs
and i dose flourish exel once per week
I have a 50 dollar petco gift card and i might purchase a GLA 45g co2 system

no you don't need co2. But that's alot of light. Might have algae issues if you leave them on to long.

I leave them on for about 11 hours a day. I know its a long time and i do get some algae, but the plants still arent looking the best

I'd say go for CO2! Reduce your photoperiod until you get CO2 on the tank. Remember, as long as there's light on, photsynthesis will be occurring, and if you're short on CO2 compared to the length of lighting, your plants will be trying to create sugars and grow without a key ingredient.

It like trying to bake a bunch of cakes. If you have a lot of sugar, flour, butter and chocolate, but only two eggs, how many cakes can you really bake?

CO2 is an option for those plants. With it added, your swords and wisteria each alone would probably conquer your tank. It sure does accelerate growth!

Anyone heard of the waterplant 45g co2 system?

it sounds like those mini 45gram co2 systems that cost allot in the long run and last less than a month. but maybe you should try amazon for product reviews

Fishe 12-15-2012 03:16 AM

Its not on amazon, anyone else used waterplant co2? And bump for anymore opinions about co2

You could always do diy c02 & use the giftcard for something else! Thats what I would do. I currently run diy c02 & get a months worth of c02 out of a batch

i would go with DIY. its pretty easy to do and a bag of sugar and some bakers yeast will set you up for quite a while for a lot less than those 45g systems cost. if you find you want more CO2 with DIY, a gang valve and another empty soda bottle can get you there, or you could just find a really big bottle and use that.

Im not a fan of diy co2, i like a clean look, not the scetchy mad scientist setup. Thanks for the suggestion though
