??? - 5cc’s is only .169 oz, do you mean 5ppm worth?
Your cya counts as 70 (always round up if between two lines) that means your target

fc is 8-10ppm

You also didn’t list your ch (calcium hardness) which may also be high if you’ve been using cal hypo.
70 ppm cya is a bit high for a manually chlorinated pool but it’s usually doable for a little while until the level comes down so long as you remain algae free. The exception here is that you have an unknown amount of bromine in your water so every time you add fc you’re just reactivating the bromine. The bromine is not protected from the sun by the cya like chlorine is so you go from fine immediately after dosing to no sanitizer by the end of the day. The algae will return if it hasn’t already. If you drain/do a water exchange you will be in a position to actually do the
SLAM Process & win the battle along with ridding yourself of your bromine problems.
