Absolutely!! Thank you so much for the tip. We actually have a RO system, just haven't set it up yet. But with this RO bottled water being so costly it's definitely getting set up asap.
I also have been researching like crazy, and found the Vin system for setting up tanks for crystals. It's a whole nitrification system that takes about $100 for the full product line and 2 months to cycle. It's super intricate and I have pages and pages of notes from the tutorial, but I think it's by far the best way to go. He keeps the galaxies using this method so I know it's tried & true. He uses a 15 gallon for this video, which I think I'm going to upgrade to just to save myself from dilution calculations. Although I noticed his breeder tanks are 10 gallon. Most people recommend 15-30 gallons for the ease of controlling the water quality. That's reason enough. I saw one video a while ago on YouTube from a US breeder I think using this system, wish I could remember the name. I remember thinking this is ridiculously unnecessary, but I wasn't thinking about taking on any caridina back then. ?
Here is the video tutorial on the Vin method:
