I don't engage in sales and commercial transactions. I let the specialists handle that.
I only develop tools for my own use and if i think the reefing community may benefit, I share it. Anyone who think my idea's and tools can improve their reefing skills is free to give it a go.
DSR products were made available for the dutch reefers through the proper channels. Nowadays most dutch saltwater LFS supply the products necessary for the DSR method .
