Yeah, then you can run your return line to the cap through a de-ionizer and
continually siphon off any phosphates!

This is an interesting point in that if I don't de-ionize the replacement
water for my salt water tank I get an algae bloom.
That's how much phosphates are added to our county water, yes the water
companies add phosphate to coat the pipes to reduce lead in the water.

This filter claims to remove all dissolved minerals, all heavy metals and
phosphates.
Has any one ever tested mineral water to see how good it really is?
Can I sell any one some water?
FYI   Most good fish stores with salt water variety's sell water that has
bean filtered extremely well not a bad idea for that next coolant flush!
