Here is a thread that has picks of my rcdwc tank.
I have a new design that I will have in my hands in a week that will blow the other systems out of the water. I will be making these in 28 and 36 gal sizes. The only difference in these and that 36 gal tanks shown in that link is the port hole will be installed higher up. I saw where a tank system designer/promoter here thought I had built in redundancies, well he just did not know what he was looking at. They come with 2) 1 1/2" feeds, 2) 2" drains, 1) 2" overflow,2) 1" fitting for aeration, I just use one of them. The circulation inside this tank with the air exactly where it needs to be it what will separate this from the toys. That and being built like a brick shit house and having options that no one else is offering.
Those tanks I designed for TK were used by someone else. Having all that plumbing underneath and those raised floors made for the baddest looking room I have ever designed. I would not have pushed my designs so far if TK did not ask. Real glad a friend of mine bought it, except it makes my room look like crap and me a little jealous.Those 135 gal tanks makes growing easy and your variables steady as a rock.
I was planning on selling my company by now, and was planning on helping them with the Long Beach show. They were trying to offer me more but with less up front. I was asking so little it was not worth the wait. I would rather have cash in the hand then two birds in the bush. I will try and see if the show has any booths left and if I can deal with the time and money to be there. Great place to look for a buyer though. I will still try and get my tanks in PNC, I will have to see G and see what can be worked out. That way a few people can see feel touch. Suerte JK
