How fast should phosphates rise? Confused when I need to address the issue

[suprstrmis]

got my water tested at the pool store today and i was surprised at how much my phosphates jumped.

almost exactly a month ago my i was at 490ppb and today when i checked i was at 748. is it normal to jump that high in 30 days?
in april i was at 146 and may at 237.

we have definitely had more swimming this month.
Our numbers were as follows
fc: 1.5
cc: -
tc: 1.5
ph 7.7
alk 84
hardness: 227
cya: 31
iron: 0
copper: .1
phosphate 748

i'm trying to understand when phosphates should be addressed and what to use because it seems like phosphate clearing chemicals can be particularly toxic. is it good practice to be using algecide on a regular basis?

This is your first problem, pool store testing. I am PoolStored, ask me why... Phosphates don't matter, ignore them. Get a good test kit. Link-->Test Kits Compared

We don't trust pool store testing. But your FC is low for your CYA. Add 5ppm of liquid chlorine a day until your test kit arrives, then post up your results.

Do not use phosphate removers. Do not use algaecides.

Some great reading:

Recommended Pool Chemicals

Which should I buy? TFP's recommended pool chemicals are cheap, easy, and won't unbalance your pool water.

Non-Recommended Pool Chemicals

These pool chemicals should not be added to your pool. Save your money and frustration and avoid these chemicals!

As much as I agree, I also respectfully disagree.

fc: 1.5

cya: 31

We may be gifted a swamp while standing on line at the poolstore. A problem, before the problem would be the first problem.
