Why hire a whirly when I have my own Cessna Citation Excel?
I was considering a large water filled case and running one of my Eheims through it from a 12volt supply with an inverter, I'm less concerned about temps as air temperature will be around 28 degrees fairly swiftly (10ish hours) and it will be done in Summer.
Would I still need to separate the fish to avoid 'stress' based aggression?
300kg on a reinforced concrete floor wll be fine, I have exactly that myself.
To be honest it weighs about the same as a bath full of water, and it's never going to trouble a solid floor. 250 litres isn't that big in the grand scheme of things and personally I'd only worry about it on one of the new lightweight timber floors.
That said if you're really concerned about it then get the SE in...I wouldn't bother.

OK, with Ammo-lock in the tank you may well get a reading for Ammonia. It's in there it's just been converted to a safe form. However, without an available Ammonia source there shouldn't be anything to be converted into Nitrite. As I understand it the Ammo-lock will lock the Ammonia away making it unavailable. Also without a running a cycled filter there's unlikely to be any bacteria to convert the Ammonia anyway.
So, a Nitrite spike is unlikely. I'm assuming that you are adding Aquasafe in the correct quantity to suit the amount of water you're adding at your water change rather than the whole tanks volume.
All of this can of course be confirmed with a decent test kit. The API master kit is well thought of on here, indeed I use it, it's readily available although if you can't find it eBay always seem to have sellers.
