Need a little help with a ?
Its probably stupid but here goes . I plan on setting up a ten gallon tank -28 watt cf light-ehiem classic filter-black sand or flourite substrate - plants will be mosses, anbius, java fern, mabye a few low light stems. My ? is about the co2 . I will have to use diy for now and I was wondering how to tell how much co2 is in the tank and how to prevent getting too much co2 and also with the plants will the sand do or should I get flourite ?
