C02 question

[superjalami30]

I have a little 3 gallon tank I've recently planted with dwarf pygmy chain and a few other small plants.
I plan on using KN03, K2S04, seachems "comp" and "iron" ferts and a few other odds and ends.
I want to add C02 as well, and planned on using the DIY method.
If I used this DIY method I thought I may send the C02 bubbles up my filter for diffusion.

The filter I'm talking about is one of those "waterhome" filters.
KIT:

filter

The question is as follows:
If I were to difuse the C02 by sending it threw "this" type of "open" filter would it defuse enough of the C02 to be worth while?

If anyone has seen the kind of filter used in these waterhomes, you'll know what I mean.

thanks

I dont know about the Waterhome.

But for a tank that size, an inverted bell should be enough to disperse CO2.

An inverted bell?
What do you mean exactly?
A pot of some sort to catch the bubbles on they're way up?

Hiya superjalami

Not sure what i would do with a tank that size, i dont think those filters are known this side of the world so im not familar with them.

An inverted bell or any object (imagine the bottom 2-3 inches cut off a plastic mineral bottle and turned upside down in the water, that basically is your bell) that will trap the air bubbles coming from a co2 pipe that may work for you, i was messing around with it but never really pursued it, basically get the plastic bottle and cut the end off and get a sucker and find a way to attach this to the inside of the tank, its a type of passive co2 diffusion, but i found for it to work the water had to be agitated around the bell and this sort of defeats the purpose as the co2 may be getting diffused but it was lost as quick due to the agitation of the water, like i say i never really pursued it as i was working with a much larger tank, but you may get it to work.

Another idea i had was to get a normal Hagen ladder and basically cut it down to the size of your tank so that it fits, but maybe thats an expensive way to do it but it would work, the bubbles would have less to travel but its a smaller tank and would be easier to diffuse the co2 into.

Try your filter idea and see if that works, thats probably what i would do, and just mess around with your mix, id say the biggest problem might be that some of the methods might be to efficient, but that probably wouldnt matter if you dont have any fish in the tank.

Good luck with it, if i come across anything else on my travels around the internet ill let you know.

Heres a very good link, bit slow loading, on co2, down around the middle it explains inverted bells.

thanks zig.
I use a hagen c02 kit in another tank and havent had any problems or concerns with it yet.
Superpet here has a "garage" sale till the end of the month, tonnes of poo goin' dirt cheap, I think I'll check if they have a ladder for sale, if not they only cost 10 bucks, not too expensive.
I was thinking I could use a submersable filter to catch the C02 instead of the waterhome filter, would probably work better than the original filter.
I'll play 'round with it for awhile and see what happens.

thanks agian!

I guess zig has explained the bell bit. Basically the concept is that the water stays in contact with the CO2 longer hence giving it a chance to diffuse. I use an ordinary air stone which is located at the bottom of the tank and a bell near the surface to catch the bubbles. Works wonders in my 12gal tank !!!

PS: The bell is the bottom of a small mineral water bottle attached to a sucker.

A little while ago my kid came home with a cup of candy.
This cup had a lid, and the lid happens to be clear.
I saved it because I thought I may need it for something to do with my aquariums.
Well, waddaya know.
I have a bell.
Thanks guys!
