Thank you, thank you, thank you!!! I could really wright it about 1000 more times but you get the jist. I am now going to do my tank like this. To think I was going to settle for a stock tank because I thought my dreams of a frame with a liner could not include a viewing window anyway. Now I have seen some one successfully make my "dream" come true, I can show my hubby and hopefully get on with the plans. I am going to read thru your thread one more time before I ask you any questions, but is it okay to ask some questions when I do start my build. I am going to do a diy filter too, to customize all my needs. I have quite a messy bunch of fish on my list, and diy is really going to be the only way to go about the filter, plus I actually like the look of the pvc, and it will also be use in decor for knife fish to use as home, while still being safe for rays, should they "bump" it. I am calling around to price my glass window right now, as I think that will probly be the most expensive element of the tank part. What other suggestions can you give before I actually begin purchase. I am definately blue printing first, once I get home and take measurement of the area. I am moving my 2 150 gallons to my room so my new project will be in the livingroom, (so it will have more room, we are directly on slab so no worry about weight). Your thread has refueled my excitement about doing a build. thankyou again, and btw wonderful tank! How is it doin now. I am subscribing to this thread, so plz post more pics as you take them!!!!!!!
