Many of us who have setup bioactive enclosures, or at least delved into the idea and have done the research, have seen all that the BioDude has to offer. I really like the products they provide and I think their company is great. However, they can be pricey. Recently I setup my own bioactive enclosure from my own materials not from the BioDude to save money. The one thing I really wish I had from them though is BioShot https://www.thebiodude.com/products/...t-per-6-qt-bag

It is only $5, but I'm from NY so shipping would be $7 and it doesn't seem worth that much for a teaspoon of Bioshot. I'm just wondering if anyone has come across any alternatives that work the same way?
