Its pretty hard to keep a tub of such small volume down to 30.5 in the weather we have had.
Especially if you have moved them inside now and they are doing fine.
I dont know about Pbass but I think hypans can handle a bit higher temps.

The temperature my heater is set to is 28 but it has never actually been on 28 since today cos it has been cooling down. Before I do my daily water changes temp varies between 29-30.5 for the past 2 weeks but after the water change it drops to about 27.5 and I do water changes around 4:00 everyday so I imagine it just heats back up to 28 and stays around there overnight and starts to get warmer the next day, the tank inside my house's temp is 28.6 at the moment so theres not much of a temp difference when I chucked them in there

Water parameters are the same as the tub outside and temp is 28.2. They all seem to be hiding, 3 of them are hiding behind the heater huddled up next to each other, another hanging around the spray bar and the other just laying in the bottom corner and Iv noticed they are all tilting on a 45 degree angle :S When I flick the light on sometimes the dart around really fast and then just go back to hiding again its very odd behaviour Iv never seen any of my fish act like this before. Still not eating either and looking pretty thin

Also, are you using a hose to change the water? If so make sure you run it for a good few minutes to get rid of the hot contaminated water out of it. Some new rubber hoses leach nasty stuff into the water inside them if allowed to sit in there for a while, hot or not.

Everytime I did a water change I would fill up a 12 litre bucket 3 times so I'd be taking out 36 litres and I use API stress coat and API tap water conditioner when filling the buckets back up putting in the said amount, and I was using water from a hose outside but I did always let the water run for atleast a minute beacuse I read that on another topic on this forum

obviously something has gone a miss... has to be something your missing.... is your ph constant coming in from tap water? and as dave suggested i would be using prime myself... you can overdose with it and theres no problem... even assists in neutralizing ammonia in case you get a spike.....

I stopped feeding my bass bloodworms a few weeks ago because they loved it too much and whenever I put something else in they would refuse it and since bloodworms is pretty much useless to feed fish with I stopped. I put a cube of bloodworms in today though about an hour ago and they didnt even notice it, they use to attack it soon as it hit the water splashing around and all, now the cube has sunk to the bottom of the tank so guess Im gonna have to get it out now
And as for ph coming from tap water Im not entirely sure as I havnt tested straight from the tap, I use to test the bass tub every sunday and the ph didnt change much it always be 7.8 or 7.9 it never really got to the exact colour of 8.0 on the api test kit

Originally, they may have been effected by oxygen deprivation.
The urgent emergency changing things around on them has stressed them mentally and physical water conditions has changed to abruptly.
When juvenile pbass get sick, they are very hard to turn around.
Completely different tangent:
Google (thiaminase poisoning in aquarium fish feeding on prawns).
This will be a new thing for all to learn.
Im completely against any feeding of prawn to any aquarium fish.
Thiamine, vitamin B1, is essential for a healthy metabolism.
Thiaminase is a un-needed vitamin which blocks out the uptake of thiamine.
Thiaminase is found in a range of aquatic life.
Thiaminase intensifies in volume after the freezing process.
Thiaminase disappears after cooking, is why it doesn't effect us.
Prawns are excessively high in thiaminase.
Thiaminase is partially or completely cancelled out by vegetable matter.
Fish in wild do die from thiaminase poisoning occasionally.
In wild vegetable gut loaded prey help to cancel out poisoning of predators.
In aquaria well balanced pellets like hikari and spectrum have a lot of good vegetable matter that will cancel out thiaminase to fish that are fed prawns.
But exclusively feeding prawns may outway the pellets canceling out thiaminase.
Brine shrimp frozen is a useless food once pbass is past 6cm, the fish will slow in growth and waiste if fed exclusely.
Always get your fish onto 80% pellet even if starving is the way or combining the pellet then reducing the mix till all pellets.
Stuff like prawns should only be fed once a week at most as a treat.
The best best best best best treat is Atlantic salmon from super market.
Atlantic salmon has no thiaminase and is high in astaxanthin a pure form of anti-oxidant.
But still the salmon as a treat as it can be fattening.
Have a bit of a think and good luck dude even if you have to start again.
