I have just started using pressurised CO2 on my 125l Juwel Rio tank, via an in-tank Twinstar diffuser. 6 hrs of lights on, 4-10pm, with CO2 on 2hrs before the start and off 2hrs before the end, 2bps for whatever that's worth. There is an in-tank drop checker with brand new CO2 Art premixed drop checker solution.
On the first day it went from blue to lime green after a few hours (3-4), as expected. However it's just stayed green since, throughout the 24hrs.
Fish and shrimp all seem absolutely fine. There is lots of surface movement. (No air pump).
Is this a problem? If it means there is CO2 being retained throughout the 24hrs, will it harm the fish long term if they seem OK?
