Hi Guys,
I have 2 tanks of CO2 for exchange for corals, either clams or zoas only. Got these for use with a calcium reactor and eventually sold that off so I have 2 relatively new tanks of CO2. One is partially filled and one is completely filled. Rather then throw them away I've decided to see what I can get I don't expect one person to get both tanks and it can be separate exchanges.
Do pm me if you have anything in exchange
Cheers
