I may have missed something but aren't the parameters JayC quoted for Bee shrimp, but these are cherry shrimp???
Hopefully with only 2 shrimps they will survive the cycle as 2 won't make a lot of ammonia!
You should try and cool the tank a bit as JayC states, you are pretty close to the limit. With Cherry shrimp you can use dechlorinated tap water, I do.
The IDEAL parameters for cherry shrimp are,
PH 6.5 - 7.5
TDS 150 - 250
GH 6 - 8
KH 2 - 4
Don't get too fixated if one isn't exactly in this range (ie your PH should be fine, same as mine) or where you want it, as cherry shrimp are fairly adaptable, but if you get measurements we can check those for you and let you know whether any action is required? Mine live with nitrates of 25-50 for instance, and have done for years - I am not saying they should, just that they can live outside perfect parameters.
Again, if you are using tap water it is unlikely ALL the parameters are good but the thing to do is not try and get EVERY one right, especially with tap water, and if you do want to change something do it VERY slowly! Tap water is also unreliable, every time I test mine it is different? The only way around this is to use RO water and shrimp mineraliser, but I have kept mine in tap water for 5+ years ith never a problem so unless the tap water is way off I would carry on with the tap water. If you let us know the parameters we can check if it is likely to work longer term?
Welcome to shrimp keeping and this forum!
