Info I collected on it -
Don't get an oxygen filled tank. Refills at diving/scuba stores, liquor stores. Needle Valve brass instead of copper. Co2 won't chemically eat it up too fast Recommend replacing it every 12-18 months. Here more info
Painted the background black with a little blue tint. Swapped out the blue betta for my super delta who was getting a little beat up by a CPO. Vallisnera died back a lot, narrow leaf anacharis clippings from my 30 gallon didn't work out. Cardinal plant was looking sad so I moved it up to the 30 gallon with higher light. Piled the two pieces of drift wood together and added a third to create the new mound. I like it much better now and so does my wife.
