Good day once again. I’m a new member which I just introduced myself. I live up in Whistler Canada and have little access to any aquarium supplies. IV been running C02 now for about 5 months and my planted aquarium is looking great, however due to the coronavirus outbreak I’m about to deal with a problem. My canister C02 Has just ran out after running for the past several months. Our local hardware store is not refilling metal tanks during this pandemic and I’m wondering how it will effect my plants. Will I all of a sudden start dealing with algie? Black beard algie for one? Fortunately I do have some seachems flourish excel and can get some more through Amazon. Can anyone please tell me if I’m about to deal with a major problem and if anyone has suggestions please let me know what may help. I am running high lighting for about 7 hours daily and my tank is heavenly planted.
