kevincanada Posted November 13, 2023 Share Posted November 13, 2023 i'm setoting up a tank for caridina shrimp (i'm in canada so its gonna take a while to find some) and as you can see, one of the co2 bottles is near the sponge filter and the other is on the opposite side of tank. the uptake in the left tank is much faster than the bottle further away. do you think its just boiling out the co2 or do you think the turbulence is helping to dissolve the gas into the water? cheers!

Galabar Posted November 13, 2023 Share Posted November 13, 2023 I would guess that more water motion would mean more CO2 dissolved. Link to comment Share on other sites More sharing options...
nabokovfan87 Posted November 14, 2023 Share Posted November 14, 2023 Agreed. More circulation moves more water along the bottom of the bottle, leading to more of the co2 being dissolved. (basically convection) Link to comment Share on other sites More sharing options...
kevincanada Posted November 14, 2023 Author Share Posted November 14, 2023 I think you are right. Bottom line is you get enhanced growth without risk of too much co2 and no regulators etc. 2 Link to comment Share on other sites More sharing options...
Tanked Posted November 16, 2023 Share Posted November 16, 2023 Just last week I restarted my passive experiment in the project tank. So far it is a total fail. I've either got a leak, or my house is already too cold for the sugar/yeast mixture. It worked well last year. Link to comment Share on other sites More sharing options...
jwcarlson Posted November 16, 2023 Share Posted November 16, 2023 Can't help with the CO2 question, but I'm jealous of your moss! Link to comment Share on other sites More sharing options...
