Oh, no hard feelings at all, I was just giving my 2 cents. The chances of "high grade" stainless being used in most common products is slim. And by all means use what ever you want but why even chance it being "high" or "low" grade when plastic used in something like a float valve is the same price probably cheaper, just as durable for what its being used for and you can be SURE that it won't degrade, so why even chance it? Again, take it or leave it, thats just my opinion, but I have seen many rusted hose clamps rotting away in sumps etc over the years that people have used, you must have lucked out and gotten a better clamp and by saying that I am in no way being a smart arse or anything.
So it is essentially what I am playing with - seeing what we have to do to get it to work with a NW skimmer. I think the ultimate limitation is going to be the design of the NW - the need to run the water so high in the column to produce wet foam.... Any time I shut the air off the water level rises to the cup and begins to over flow. Not a problem if the skimmer is in the sump but doesn't solve anything if the skimmer is external....
He later realized that he could have kept the tank running on the CL's only while he got the necessary amount of RO ready...... Sad Day For Reefing
