Good news! I tested the water in the 600 and found the tiniest bit of nitrate and thats it. We've got a live one people! So, as soon as I can get the pHs similar my biggest TSN (I think about 25") and my RTCxTSN (I think about 23"). I'll try to get a measurement, but keeping a fish out of the water just to satisfy my curiosity isn't really my thing, especially when they are going through the added stress of being moved into a completely different body of water. I'll be getting the pH, temp, and GH all pretty close before I move them, so there shouldn't be any extra shock other than getting chased down, wrestled with, and relocated.
Currently, the pH's are very different. I've been working on them every day, but I'm being extremely cautious in bringing down the 600, as I have no idea how much a dose actually does. Apparently, not a lot... I'm dosing it at least 2 to 3 times a day and not seeing much difference. However, I'm afraid the moment that they buffering capacity is maxed out, I'm going to see that exponential pH drop. Hopefully, I see some actual change by tonight. There's no way they are getting moved till at least tomorrow though.
As for videos, I'm up to my eyeballs in water changes and fish maintenance ATM, but maybe later tonight I'll get more videos of the setup and go through how this thing is all put together.
