I have ordered some DKH4 solution to use in my DC. Can I use liquid from Sera CO2 test kit. Doesn't look blue to me although does turn blue when added to aquarium water. Thanks.

Sounds like the right stuff. Is it a yellowy orange colour before you add it to water? If so it sounds even more like the right stuff.

The pH kit to use is the one that contains brome blue (its brome... something but cant remember the whole word off the top of my head). It should was what the active ingredient in the pH liquid is in the packet.
