Tank is getting a few inhabitants tomorrow, so i did a full test on it to make sure its still good, as its been left fishless for around 10 days now, and the canister was turned off for around 5 weeks or so, before being pulled down and washed in town water (it was feral lol)
So results are
PH: 7.4 - 7.6
Ammonia - 0
Nitrite - 0
Nitrate - 5
Very happy with that!
