DIY CO2 Question for a local solution! Help..

Hey guys , i have a 10g tank that i want to start co2 on. I did some research and found a DIY kit (the ghetto kit i call it .. 2L bottle, air hose, check valve.. using 2 cups of sugar and 1/4 teaspoon yeast)...

well it works.. meaning there is co2 exiting the airhose.. i read that the co2 needs to be difused (the DIY states to use a powerhead or airstone which i used).

But i don't feel that the co2 is being difused enough.

It comes out in large bubbles every 3-4 seconds and rise inediatly to the surface of the water.

I don't want to use a powerhead , i just don't want that much water movement in this tank.

What other options can i use to difuse the co2 better (and can i source it locally?)

Thanks in advance for the help

~Jon

Edit: I live in Midtown Manhattan (willing to drive an hour in any direction)

This will also end up being a shrimp tank (once this scorching summer is over) So if anyone has any tips of a good beginner shrimp and advice would be helpful, thanks

You could try using the wooden airstone. It worked for me in the past. Make sure you are not using a hang-on-back filter, because they could remove your co2 if they are splashing enough..

A good first-time shrimp you should try out as a beginner is Red Cherry Shrimp. They are very hardy when it comes down to water quality, temp, and look great.

20 gallon - Sulawesi Golden rabbit snails/Japanese Trapdoor snails/RCS/Marbled crayfish tank
55 gallon - Rainbowfish Dutch scape low-tech planted tank

250 gallon - Community Tiger Oscar/Red hook silver dollar/Silver dollars/PB Jack Dempsey/Clown loaches/Tinfoil barb/Roseline sharks/Bala shark Monster fish tank

Some type of wooden airstone will work a little better. Or even cheeper, use a broken off chop stick and stick it into the tubing.

If you spend a little money you can get a ceramic diffuser. They come in many shapes and sizes but all do the same thing. (make small bubbles)

I have a hang on filter (the whisper)..I run a spunge filter on the inlet because i had some fry in this tank, it reduced the volume of water being taken in. The tank's water level is all the way up to the outlet of the filter. There is zero splashing going on. Sort of a dribble really. lol

And i'll look into the RCS.. I had 2 medium grade CRS before. Had them for about 4 months till the temps went up while i was on vacation. (the temps were steady at 78* with the AC on). But while i was away the AC was off and it was almost 86* when i got home. I assume this is why they died.

Thanks.. This is a DIY. But i'd like to do it the right way.

So i'll look into the Ceramic diffuser.

Any local places in NYC that i can get it from?

I don't know about retail stores, but there's a seller out of Brooklyn on Evilbay called etech or something like that. I've bought a few CO2 accessories from them (diffusers and bubble counters), and shipping has been pretty fast. I expect it'll be even faster for you. If you do buy a glass/ceramic diffuser for DIY, there's *no guarantee* that it will work. As in, you may or may not be able to create enough pressure to push CO2 through the diffuser before the airline pops out of one of your fittings. But, if you buy a nano diffuser, it will *probably* work for you. Don't buy anything bigger than that.

Guys try to find Turkish yeast and you will see what the thing will do to your plant. Kinda hard to find here and there..
You can use hagen mini filter that you can buy in petco under $10 and use as diffuser.Attach it some more at the back of the tank to lower the better......Watr movement in planted tank is always a ++.

Cheers!!!
