One of the neatest builds I have ever seen. Looks nice!
- Curious what you have done to facilitate easy "push-button" water change, top-off and skimmer cleaning...
- Provisioning for future Calcium reactor and chiller hook up?
- How do you remove and replace the heaters? Not clear in pictures what the water level will be and if part of heaters will be exposed to air, possibly crack?
- How will the pumps be removed and serviced? Any way to add a backup pump inline, and auto-switch upon failure?
