Just to update...
It was a bittersweet night. I got my Eshopp overflow installed and running. Took a little modifying to get it to run quiet and all set up. The bulk head leaked, but I through some thread tape on there and we are now golden.
I was trying to rig up my return pump to a float switch last night. I did the DIY extension cord and $5 float switch combo from melevsreef.com (

Turns out that these little switches can't handle much of load. The little bugger overheated and is stuck in the on position now.
I bought a second one and tested it with a small desk lamp and even that one burned up. After some exploring I found and ordered a Pumpstopper kit from a site called aquahub. Looks like these switches require a relay to protect them from the current load of the pump. Not to expensive either!
I did another round of water tests to see if anything had changed over the last 3 days. Similar results:
Salinity 1.027
Ph - 8.0? (I can't for the life or me read this test accurately)
Ammonia - 0.5 ppm
Nitrite 0
Nitrate 0
I threw in a piece of shrimp in a pair of pantyhose hung them in over the side. I'll give it a couple days and check the readings again.
I guess now I just wait and see what happens
