They all arrived alive! What is an excellent way to lower phosphate and PH?
My mail-order fish arrived.

Why do you want to lower phosphate and pH?

Big water changes are the best way to reduce nutrients like phosphates, nitrates, ammonia, etc.
Lowering the pH should be done with care and only for fish that naturally occur in water with a pH lower than you have. Even then if the pH is only a few decimal points higher than the fish require, they are usually fine. A stable pH is better than a fluctuating pH.
-------------------
What fish do you have?
What is the GH (general hardness), KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).
Depending on what the GH of your water is, will determine what fish you should keep.
Angelfish, discus, most tetras, most barbs, Bettas, gouramis, rasbora, Corydoras and small species of suckermouth catfish all occur in soft water (GH below 150ppm) and a pH below 7.0.
Livebearers (guppies, platies, swordtails, mollies), rainbowfish and goldfish occur in medium hard water with a GH around 200-250ppm and a pH above 7.0.
If you have very hard water (GH above 300ppm) then look at African Rift Lake cichlids, or use distilled or reverse osmosis water to reduce the GH and keep fishes from softer water.

You need to reduce the GH and KH because the pH won't drop with them that high. The simplest way to do this is to use reverse osmosis (r/o) water or distilled water. Mix it 50:50 with tap water and you will drop the GH and KH by half (to 150ppm) and the pH should drop to about 7.5
