Brute container leaching phosphates...

[eric w]

Hi all,

I was going through this older post and have a question for Randy...I tested my fresh salt mix tank....and i got a 0.05ppm phosphate with a Hana....it is made of medium density polyethylene white plastic....I saw where you said that 0.05ppm is nothing....I started to run gfo in my tank a couple months ago and still get 0.03-0.05ppm in my DT....should i just bump up my gfo to rid my DT or chase it with new holding tanks? Thanks

Randy is on hiatus, probably sitting on a beach with his toes in the sand. . Now on to reality, .03 to .05 is right where you want the po4 to be, going any lower may starve the corals.

Everything changes from time to time. If I am trying to make ultra pure water, I don't want any leech. Different strokes for different folks.

Came across this thread while researching the topic. Like with most subjects it seems everybody has different experiences. Im relatively new to the reef hobby but have over 35 years experience in the plastics manufacturing industry. Without going over lengthy details about how the plastics industry operates I will just say that exactly what is in a particular plastic container will vary from production lot to production lot. Some variation can be significant and even to the point of being made from the wrong material or recycled vs virgin material. The label on the container is only as good as the supply chain who provided the molder with raw material and only as good as the controls within the plant that produced the end product. So Im not at all surprised that everyone has varying levels of success with any line of containers.
