Trying to think of the most cost effective because lower costs means more profit for any betta babies sold turning into more nice bettas for me.

I was thinking of switching from betta spa to using a blackwater extract for in my spawning tanks, the water in my area is fairly hard and bubblenests do not stay very well unless I use a good amount of the betta spa, and the spa is costly to buy local or have shipped.

I was thinking that boiling the leaves and making a black water extract would be more economical because I could then store the extract and use when needed, and also I could experiment with exact amounts of black water extract needed to get my ph in a good range right away verses just chucking a leaf in and waiting.

What do you guys think about this?

blackwater tea bags i love them, they are cheap easy and at the ready as and when you want, no preserves, no chemicals and no aditives. Wouldn't use any thing other...i have dropped IAL for these too
