Good day folks, firstly I hope all are well and learning to live differently during these hard time. IV been fooling around with freshwater and marine tanks for the past 8 or so years. I recently moved and due to lack of space downsized to only one 75g planted aquarium. I joined your forum as up to now IV been able to figure things out by myself but due the the coronavirus outbreak I am needing some help. I will post my question in the following post re Co2. Cheers and stay safe.
