Danny, I dont have any drawings of mine, just pics. We had many long threads on RC about them.

Here is a dandy on Eric,s forum. It has some drawings I believe.
This one is a discussion between turf scrubbers & refugiums. I believe it also had some drawings but also a few heated words, as some wanted more pics and detailed plans. You can see my response on that.

There are lots more on RC arguing the benefits or non benefits. I,m not sure if its in one of the above or not but one had superb pics of Inland Aquatics.
