It sounds even better than I imagined. That is some extremely low ph. The Blackwater theme isn't done enough IMO. Most people want "crispy" water. I myself am guilty of this. But with proper stocking and aquascaping it can be very beautiful. Gotta love the Mangroves. I hope your health continues to improve so that you can enjoy a long time with your family and the hobby. I'll be waiting for the pics.
