Mind me everyone... What is this color card and what are you talking about? I am totally new to aquarium life... Having a fresh water tank with not certain of how many gallons...
First if you don't have one get an api liquid test kit they are a must have with fish keeping , some tanks don't require as much maintenence, I know of people who do one every 2-3 weeks, but I do mine every week as most people do because when you take water out and add new treated water back in you replenish the minerals the fish need. Do You use prime water conditioner? Of not I would also recommend that, make sure you temperature match the water going back in also.Okay. From next weekend i will start doing so. [emoji106][emoji106]
