I finally finished getting the auto water change set up today using the Litermeter III. I'm starting off with 1.5 gallons a day and will see how things go. If needed I'll go up to 2-3 gallons a day.
I also found my Green Bubble Tip Anemone today that went missing! He seems agitated after the move to the 300 from the 90g and kept moving around. He finally a week ago disappeared and figured he was buried in the rocks somewhere. Low and behold he was in my sump! The hard part to figure out is how the heck it fit through the weirs in my overflow, as that is the ONLY way into the overflow! Then he traveled through the 1.5" pvc drain...through a gate valve, and into the sump! I have him attached to a small rock now in some tupperware in the sump to keep him relaxed and hopefully heal up. He is inflating but looks beat up some. Hopefully he'll recover! I plan on moving him back to the DT tomorrow to see how he does.
Apparently my emergency drains work perfect as I KNOW he caused one heck of a restriction in the Herbie drain during his trip from the DT to the sump!
