2 Co2 Diffusers

[johnnywortho]

i was just wondering that because my tank is fairly planted would it be and safe idea to have to small glass diffusers on easy side of my tank. I currently have just the 1 centered in the middle of my tank and feel that the plants on the edge are not getting sufficient co2, is this the case or is it just me lol

Its may be that your filtration is not good enough to push the co2 round the whole tank?
From what im aware, having 2 difusers isnt a problem.

It would probly be a help if u listed your tank size, etc.

Im no pro planter by any means, so take my comments with a pinch of salt

If you think the total amount of CO2 is OK, why not install a T piece at the outlet of your CO2 generator, from which you lead pipes to both sides of your tank? This should be 100% safe.

That said, if you think plants at the other side of the tank aren't getting enough CO2, your water circulation might be too weak. It seems reasonable to assume that if the CO2 can't reach them, neither can any nutrients in the water. If there is no water circulation, plants will develop a nutrient-free layer around their leaves.

my tank is a rio 180 so i believe thats around the 46 gal marker. and with the water circulation i think that is where im going wrong. I currently have 2 internal filters in my tank. the standard juwel filter and also a eheim 2212. Now both of the outlets are directed upwards to disturb the waters surface for oxygen within the tank. maybe i should place one of the outlets directly into the tank causing the water to circulate. But still i will be trying the 2 diffuser idea by just teeing off main co2 supply.

CO2 evaporates really fast if you cause surface turbulence. I've been moving my powerhead around in my new planted tank a lot lately, and noticed a major jump in pH the day after I increased surface turbulence, which most likely indicates the CO2 was no longer staying in the tank properly. So now I'm going with just enough current to move the surface a bit without creating any ripples, and my pH has gone down accordingly.

Since I don't have fish in the tank yet I can't say this with absolute confidence, but I'm under the impression that in a planted tank the plants will take care of producing all of the needed oxygen. This is what I'll be counting on anyway. My sword plants are literally bubbling like little air stones, which suggests that the water is pretty well saturated with oxygen.

Sorry, plants won't provide all the oxygen needed for the fish. Its surface agitation which is where most of the oxygen in the water is absorbed from. Yes you will lose some CO2 when the surface is agitated.
I can run my CO2 at a high count, with surface agitation, but with none I quickly learnt my fish are NOT happy!

i was always under the impression that if you were adding co2 you didnt want surface agitation and that the plants WOULD supply more than enough oxygen??

Sounds right to me especially if all the plants are pearling
