I just picked up a really nice 60"w 30"h and at the widest 30" half cylinder aquarium. I think it's 140 or 150 gallons. I sandwiched potting soil between layers of flourite.. I'm using the biggest fluval 806 canister, I have a Current+ led, should I add another or t50's the width of the aquarium I need more coverage, plus it's a deep tank.. I want to use red plants so I want to add CO2, my local aquarium store told me I'd be better of Not injecting because the co2 won't be distributed evenly. Is that the case? From what I read Co2 is crucial part to optimal growth certain red species.. Will excel be my solution or is dosing a option?
Thanks

Here's a better picture.. I'm using a diatomaceous filter to clear substrate dust from the water.. I also jumped in with some Amazon swords

As long as you have sufficient water column movement (e.g. with some powerheads) you will achieve reasonable diffusion of CO2.

You are correct in that CO2 is integral to good plant health; this goes along with light as well as fertilization.

I would not go with Excel, especially with an aquarium as large as yours. It would be extremely expensive and uneconomical.

Do you recommend using a reactor? Btw what are your thoughts and recommendations on lighting?

Sounds like they have dollar signs in their eyes thinking how much Excel you'd be buying from them. With a tank that size, a giant CO2 cylinder is about the only option that won't make you go broke.

I'd be questioning how much to rely on my LFS if they were to give me that sort of advice. As per Darkblade, reasonable water movement will distribute it just fine.

I have 1 48"and 36" Current+6500k/led is this sufficient? The tank is 30" deep...

Are these the ones? http://www.drsfostersmith.com/produc...m?pcatid=26107

If so, they have almost intensity to speak of, especially not for a 30" tall tank.

Yes that's what I have... Should I add another one?
The 48" 30wt, par 21 @24" and the 36"is 24wt, par 21 @ 24"depth..
I was told the Marineland LEDs could be added..
I will start dosing Metricide initiially..substrate is a Flourite, organic potting soil sandwich..
