Thanks for all the info, but since my mind is like a sieve, can you give me those powder paint colors again?

Not a very good picture. But it's no more than a 1 1/2 in coupling with a hole drilled in the side above filter and silicone D or glued in. I use mainly 1 1/2 in cups. But you can get the 2 in and do the same thing with a 2 in coupling. You just push the cup in as you twist it to get it to seal. Use a aquarium air pump to power it. Just a cheap one will do.[/QUOTE]
