Can you overdose chemipure?

So i wont add chemipure blue until i get a phosphate checker. Does it allow you to feed more heavily as it is stripping nutrients?

You should keep an eye on your nitrates and phosphates levels and aim to keep your alkalinity between 7.5 and 11. Magnesium is a mineral that varies slowly yet is very significant. If you have hard corals, calcium is also crucial.
You may test for a variety of things, but some are only useful if you have specific items in your tank.
These settings vary as your system ages, and you must adjust what you're doing.
