What equipment upgrade made the most impact on your tank?

Hands down Neptune Apex controller and monitoring. Total change in stability.
Then second to that is moving to moonshiners method and deleting water changes.

Another vote for adding an Apex controller plus other Apex modules. It allow me to travel for two to 6 weeks at a time and still monitor my tank. I just have someone stop in the house once a week to check on things and water the plants and refill the auto feeders when needed. If there were an emergency, I can talk to the "sitter" through the camera and talk he/she through whatever is needed.

I'd like to throw my support behind the Apex/Trident controller too.

I've been enjoying this hobby for 2 years now, and I'm really pleased with how my tank looks, all thanks to the Apex. It's been a fantastic tool for understanding the daily needs of my tank, making it super easy to adjust everything to keep it stable and thriving.

Honestly, if I had to rely on manual testing, I probably wouldn't do it nearly as often. Having access to more data just makes everything so much clearer and easier to manage.
