So I have had this tank running for a week but I only had it half way full filter and heater where still on I have filled it up yesterday to the top and have bought two nitrifying bacteria’s which one is best to use and how do I do it I’ve never had a saltwater before to I’m a bit stuck with the cycling process and should I test it now ?
And do I need a refractometer if I got my water from the fish shop
