I find that with glass under 3/8" you won't notice any appreciable difference in clarity between regular float and Starphire/low iron. At 3/8" you'll start to see a difference and at 1/2" it is significant. So for a 180 gallon using 1/2" glass Starphire is a good investment if you are planning to keep the tank long term.

Oh do share please.

He is probably buying if from the larger outfits like Bronco, Tempa, or Garibaldi but they won't sell to the public you need an account. This is where the other outfits buy it from.:wink:

It is actually a small manufacturing plant by the Port Mann, and I am the public

Oh the other outfits wanted to know where I got that price because it was less than they pay.

Ya $3.50 for 1/2" is very good better than what I can get it for.
