When to start dosing

I'm having some issues with my ph and alkalinity. My ph swings from about 8.02-8.2(reef keeper ph probe) over a 24 hour period. My alk stays at about 7.2 dkh(Hannah). I do a 25 gallon water change once a week(reef crystals)

There's nothing wrong with those numbers. Ph will naturally drop when the lights go off and as long as your able to keep your element levels steady with your wc's there's no need to dose. Generally dosing is only done when you have enough stony corals that your element levels are being depleted faster than you can replenish them through your wc

You can minimize the pH fluctuation by turning on sump/fuge light only at night.

If all your corals look fine why change anything? If it ain't broke don't fix it

PWC`s Will provide all the replenishment of trace elements needed in most cases. The exception would be calcium in a few cases.

Hint, good Alkalinity will help stabilize pH. If you can raise it with pwc then that's good. The question is, how much and how many times to reach the target level. But bribo has a good point. If nothing looks unpleasant, might as well leave it alone.

I agree with this also. Some times reefing can be complicated but most of the time the KISS method is best.
