Great I will be attending to that soon.
Since everyone is so knowledgeable. Another question to add.
What is the balance of pumping C02 into the tank with fish breathing the oxygen? Why is the C02 not a danger to the fish? I got a bubbler for the simple reason of thinking there was not enough oxygen already. Although this was on my 20gal at first I can't see how adding C02 would help that cause lol. Great for the plants not so great for the fish. Or is it something like a 12 hour cycle. C02 during the day for the plants and oxygen at night for the fish and plants.
