auto water change

This video took a long time to make. Mostly due to poor planning and a continuous need for more plumbing parts. Thank goodness for Lowes PVC department. They have it nicely organized and easy to find stuff. Not so much at Menards... For some reason I always seem to cut myself and get bruised...

i want to setup an auto water change with dosing pumps. I want to use Neptune systems or GHL and I’m leaning toward Neptune, but the cost is very high. I was just wondering the thoughts of other reefers in the community??? And maybe what setups others are using?

I know this is a pretty HOT topic! I currently use the Neptune DOS that connected to my Apex controller. I have it pre-programmed to take out a certain amount of milliliters throughout the day. I love it but it's a bit noisy that's for sure! It's ok for me b/c mine is installed in another...
