Does Excel Dissipate like CO2...???

Hi Everybody,

I just converted my standard 55 gal. tank to a Planted Aquarium. It contains small crypts (about 20), anubias (about 15), Compacta Swords (6), 4 5" SAEs, 3 Chinese AEs, 3 Bamboo Shrimp and about 15 Freshwater clams.

Its cycled, so that's not an issue. However, a few hours after the lights went out I could tell from the fish behavior that O2 was low--so I added an air stone. I understand how this would affect CO2--but does it have any affect on Flourish Excel....???

I've searched, but I cannot find an answer to this specific question, so any info would be Greatly Appreciated!!!

Thanx!

CO2 is a gas. The active part of excel is a short-chain hydrocarbon. For that reason it isn't able to leave the water into the atmosphere. Run your airstone to your heart's content.

Actually, I've seen a friend test O2 after dosing Excel, and O2 drops a little. Its a good idea to run your airstone to increase O2 levels in the water.

Here is Seachem commenting on how large overdoses of Excel may actually reduce the amount of available O2 in the water. Not trying to move the thread in another direction, just expounding on malkore's observations:

One thing to note... The gluteraldehyde is sensitive to UV and the chemical breaks down... so.. I dose Excel at night after tank lights out. It's probably not a big deal unless you've got a UV steralizer.. I'd turn that off if you're going to use Excell... especially if you're going to overdose it for algae treatment (works awesome by the way).

Some peopel store Excel in the fridge too, mainly to prevent too much exposure to sunlight. But that's why they make the bottle opaque

If you had real gluteraldehyde and not the altered version used in Excel, you would wanna keep it cold.
