When I put tank together seven months ago, I believe 7 or 8 outta 10 bags of Eco-Complete had the milky liquid. I didn't like the looks but didn't realize it was dangerous.
Just read crshadow's caution about this milky liquid and I became very afraid .

I just got my first Phosphate tesk kit; also AquaPharm.
My Phosphate showed 5.0 from tank and 2.0 directly outta the tap without water sitting, just out of the tap.

I have been dry dosing ¼tsp. Phosphate every other day for months.

What should tank Phosphate reading be?
I should know this but...

Should I stop adding Phosphates to tank?

Can high Phosphates add to algae problems?

Thank you.

Generally your phosphate should be a 10:1 ratio based on your nitrates. If you have 10 ppm of nitrates you want around 1 ppm of phosphates.

I would stop adding phosphates. Unless you have a huge high light tank you are adding a LOT of phosphates.

Phosphates alone really don't cause algae. But the nutrients being out of balance can.

5ppm is not a disaster. I would stop dosing phosphate for now. After a few weeks, right before a water change, measure PO4. This gives you an idea if the PO4 from tap water is enough for the whole week. If the level is real low(like <=0.5ppm), consider a mid week boost with PO4 dosing. Otherwise, you can happily ignore PO4, one less thing to worry about.
