Saturday Tank drilling

[Canadian Man]

Bob,
The larger rio's seem to be the ones that cause everyone their greif :rolleyes:

Many people that use the smaller ones dont have any problems with them. It seems to be when you get to the 1700's and larger.

If your intrested, it is one of the easier projects to build. The one concern with the cpr refugium is i believe that it is ment to hang inside the tank, not outside?

Deb, Will do:)
