Thank you both for your input you are correct that the test is probably going to come up zero because the phosphate is being used by the bacteria and any algae in his/her tank.
But that is not where I am going with this. Pez touched on it in that the testing of the source water is one aspect where the kit can be helpful. However if we are using RODI units and maintaing them properly with an inline TDS meter we will avoid using any water with phosphates in it.
Which brings me to my belief in process control. (the auto industry uses this to maintain and increase quality in their vehicles and as you know cars have better longevity now more than ever).
The testing for phoshpates are at best an after the fact useless test. If we have cyano we know we have excess nutrient in the tank and need to do some root cause analysis as to why it is there.
However if we put in place processes and controls to keep our tanks free of excess nutrient in the first place, why would we worry about having a problem in the first place, why would we need to test things after the fact. Husbandry is all important in this hobby. I agree that there are multiple differing processes to get to the same goal, but whatever process we use we need to be diligent about it to maintain our systems.
That said, I can tell you that I have not tested for ammonia, nitrite, or nitrate in probably a year or more. I can tell, now, that my coral are doing what they should, fish and inverts are acting the way they should, mostly by looking at my tank. If I see some algae starting to grow I know there is excess nutrient in there.
The equipment, dosing, and livestock are all process controls to avoid the unnecessary after the fact expense in time and dollars of testing after the fact.
We can discuss this more but for this post I'll leave it at that and see where it goes.
Some would go as far as to say that test kits are for newbies only. I use them for handiness more than anything. Some people get things down pat and never even test for sg. They are handy to have though.
