Tested today and it’s alk 7.5 and calcium 436

I’d just keep checking once every few days. :)

How do I just maintain 450 and 8.0 without it swinging

If you want 8 dKH, then you should start slow dosing now. Bear in mind that exact calcium levels are not needed. Any value between 400 and 550 ppm is fine.

What would be a slow dosing amount ? Like 5 ml per day ?

I'd add 0.1 dKH of alk per day and see what that does after a week. The volume depends on what you are dosing to what size tank. This calculator may help:

That’s a fine choice, just wait a few days after dosing to see the alk rise.

And what is the appropriate starting dose 5ml per 26 gallons per day ?

And what is the appropriate starting dose 5ml per 26 gallons per day ?

I recommended adding 0.1 dKH per day, which is about 2 ml per 26 gallons per day.

I recommended adding 0.1 dKH per day, which is about 2 ml per 26 gallons per day.

so 183 times 80% is 146.4
146.4 divided by 26 is 5.63.
5.63 times 2ml is 11.26 ml
So does 11 ml per day sound like a good starting point ?

This is what it has looked like at 11ml per day… this looking okay

Bear in mind that it claims +/- 0.02 ppm when used perfectly. Make sure the cuvettes are very clean, even on the outside, and used in the same orientation every time.
