OK yall, I have a successfull CO2 story, although it's a little too successful and now I think I need some sort of shut-off to offgass the CO2 at night.
I was browsing the net for improved DIY CO2 yeast concoctions (and NOT noticing this wonderful little thread, doh https://www.plantedtank.net/forums/di...diy-setup.html
So here's what I used.
1/2 tsp ammonium phosphate
1/2 tsp buffered Vitamin C powder (from my reefkeeping)
1/4 to 1/3 tsp wine yeast
1 tsp baking soda.
Mixed with RO water.
24 hours later, I'm getting more CO2 than I've EVER SEEN in my life from a DIY concoction. Hard to get a bubble count but it's easily too much for my 10g tank lol!!!
I used these DIY reactors (baker's yeast) for YEARS back in the 90's and early 2000's and never saw anything like this.
So now, how do I offgass this at night? Tonight I'm going to redirect the output of my canister filter such that it rolls the top of the water a lot more.
I could put on an air pump on a timer, but I want to avoid the bubble splash and I don't really want an airstone in my tank all the time.
Is there a solenoid that would offgass this? I know I can't use a normal solenoid since it would blow the bottle lid off and really piss off my wife.
