Ive done alot of research but let me explain my set up for you. I have a 6 gal tank that is approx 12 inch tall. It is a fertilized and currently has a DIY co2 on it, i did this by taking a 2 liter bottle and adding sugar and yeast, it is connected to a special co2 bubble (whatever they are called). The tank also has high lighting and is completely planted carpeted and bigger plants. Im about to be adding in my cherry shrimp and know that gassing them with co2 is possible at night. And im wanting to avoid this of course. Yet i dont want to spend alot of money upgrading my co2 system. The co2 bubblier is only 8-9 inchs from the water line. The majority of the bubbles reach the surface meaning not all the co2 is dissolving or there are other gasses present. Im wondering if I can get away with this co2 delivery system. Or what simple upgrades could be made so that it doesn't run at night? from what i understand it would be at night i would gas the shrimp? Also I do a 50% water change 1 if not 2 times a week. 

 

Options ive thought of-

1. Instead of a 2 liter bottle maybe like a 12 oz bottle, scale back the yeast and sugar so there is less co2 being produced

2. Releasing the pressure in the DIY bubblier before bed. so it would take maybe 4-6 hour for the pressure to build up again and start bubbling 

3. Upgrading system (Dont want to do this really, but i though of it)

You can turn the CO2 off at lights out mate, u don’t need it during the night when there is no lighting period.

@TheKeeper, it is very difficult keeping plants and shrimp together in a high light/high fert tank. It's one or the other. A compromise is needed. 

Since you don't want to spend money to fix the overnight CO2 gassing, then then shrimp has to go.

Alternatively, I question how many plants you can have in a 6gal the needs co2.

What plants do you have?

Can you change them to low light mosses, ferns or subwassertang?

 

 

@WhySoCRS, you can't turn off DIY co2. It keeps producing co2 in the bottle until all the sugar is consumed. If it is blocked to stop the bubbles from coming out, the bottle explodes!

I can stop it by releasing all the pressure in it before bed. meaning it actually wont bubble again for 4-8 hours till the pressure builds up again. Thus delaying the co2 build up. Any suggestions for a cheaper co2 delivery system? Cause im very interested in having the full carpet on the bottom and i love the stunning green co2 provides.

@jayc Also, its very do-able to have both shrimp and a planted tank, I see it done to often.

I currently have S-repens (carpeted), and ill be adding  Pogostemon helferi, mayaca fluviatilis

Love the Pogo. You will have to post some pics. Pleeaassseeeee.

I didn't say it was not doable. It's difficult and requires a lot of attention. As long as you can maintain a tight regime of monitoring water parameters for both shrimp and plants, then it's doable. But alas, I'm lazy and busy.

Don't know of a cheap system. You'll need something with a electronic solenoid on a CO2 tank that will shut off at nights.

@jayc Thanks for the help and advice, here in a couple of weeks once I get the system up and going and deside on what to do I will definitely post pictures!

Yeah I misread this as DIY CO2.

why don't you remove the co2 diffuser at night? and just put it back in the morning. Sure it'll be a slight hassle but its better than gassing your shrimp, there's no need to release all of the pressure from your diy co2 kit. Alternatively you can leave it in and just purchase an air pump($10-$15 for the cheapest ones) and turn it on at night, I believe it'll be very difficult to produce enough co2 from a diy kit to gas your tank as long as their is an air pump running aswell.
