Polyethylene Plastic Frag Tank??

[steamboat]

Does anyone use polyethylene tanks for their frag systems?

The tanks seem to be very affordable & well built, however, there might be a catch because this online company I found sells a much more expensive model designed to hold salt brine. Will the salt start to eat away at the plastic or are there harmful chemicals the polyethylene that will impact the corasl? Here is a link for one that I thought looked interesting --http://www.plastic-mart.com/class.php?item=3314

Who has one of these setups?

I have been using these for at least a year with no deterioration or chemical leaching(at least not what I can test for). Corals look great and grow, so I am happy. I did need a bulkhead gasket for both sides due to how thin this particular tub is. Those can be made out of large rubber body washers from HD as well(use the stock gasket on the wet side.
