My new 240 RR. Ya baby!

Yes Paul did have a few recommendations, but unfortunately it would mean having a 1.5" drain over the side of the tank. He also gave me the idea to use the two 1" holes, but they may come up a little short for some pumps. I'm sure I'll be using the Dart for the closed loop which I've seen on different sites having either a 1.5" or 2" inlet. If it's a 1.5" (1.77 S.I.) inlet the two 1" drains will yield 1.57 S.I. which I hope to be enough since there is no head pressure and a short drain line reducing any line friction. I know they say not to restrict the inlet.
Anyway I'm done staining the stand and doors and need to start tearing down the old tank.

Happy Valentines Day.

I got the idea from someone on this board. He had the drain going to a Dart and then the return was plumbed through the return and the OM unit was physically above the tank. Looked really clean and took alot of plumbing out from under the tank. He was also using loc line as his returns, two 3/8" per om return.

Aneglo, thanks for the beautiful boquet of flowers. All I go was a card from my wife!

Can't you drill a 1 1/2" or 2" bulkhead in the back of the tank for the closed loop? I'd recommend to drill for the supply and then return over the tank for the returns from om unit. I drilled for both supply and return and glad I did. Most don't like to drill though.
 
The tank is/will be setup as a peninsula. I do have the one end that I could drill through. I'm a little hesitant since I've never drilled glass before and I haven't even got the tank wet yet. Do you really think the two 1" bulkheads won't be enough for the Dart? I'm not worried about the plumbing under the tank since everyting else will be behind the wall.

On to progress - I've gotten the stand completed and I've been working on taking down the old tank and waiting on extra help to move everything. I was hoping to it all moved last weekend but I didn't have enough time. I'll try again this weekend. So far I've ordered my bulkheads, ball valves, Dart pump, and RO/DI replacements.
 
I have 2 - 1" bulkheads supplying my pan world ppx50 (rated at 1110 gmh). Seems to be fine for this pump. However, the dart is much higher output pump at 3600 gph. I'd go with 2 - 1 1/2" supply. I'd look into an OM with the 1" returns and at a minimum use 1" returns, but would recommend 1 1/4".
 
After talking to a local glass shop and looking online for a bit to cut the glass I don't feel comfortable doing this myself. I'm going to have to bite the bullet and put a 1-1/2" or 2" drain over the side of the tank. I really wanted a clean look but I can cover up the pipe since it will be a peninsula setup.
 
check with your (trusted) LFS. Mine ran $20 a hole. Just dropped the tank off and 1 week later had the 6 holes cut where I wanted them to the size I wated them. There are some DIYers out there that cut there own holes. I'm not quite that brave (yet) lol. Over the top should work ok for the closed loop portion though IMO.
 
The glass shop wanted $50 a hole and they wanted the tank at their shop which I can't do. The tank weights about 600lb and I don't want to move it any more than I already do. I'll live with the drain over the side. The returns will be through the bottom and I can dress the drain line so it doesn't stand out. I really thought I had planned everything out before I ordered the tank, oh well.
 
Guess it would be difficult to drag that puppy down to your LFS! The over-the-top supply will work for the CL. One more reason I went with 2 supply lines was to decrease the pull through the strainer so that animals would not get stuck on the strainer, also for redundancy. Good luck with endeavor. Keep me updated and show some pics.

I just spoke to GC from where my tank came and they assured me that the bottom pain is not tempered. It is doubled 1/2" though. I'm thinking maybe I should just redrill the drain hole. I thought the glass would have been tempered and I called a couple of times to ask Tom but he's been out of town. Maybe I'll give it a go. We'll see,...
 
Just ordered the diamond hole saw 85mm for a 3-1/4" hole. I'm putting a 2" bulkhead in. Should be in next week.

Well I did it. I drilled the tank without any problems until the last second. I took my time and all was going well that is until I took one hand off the drill to grab the water for the bit and that's when it happened. I was at the bottome of the glass when the drill twisted in my one hand and caused the top edge to chip out. I was soooo close to a perfect cut. I spoke to Tome from GC and he said to use some silicone when I install the bulkhead. I've never had this problem so if anyone can chime in please do so. Should I just cover the hole with a piece of glass and redrill. I thought what if I took a piece of glass large enough to cover the hole, pre-drill it then place it over the chipped hole and siliconed it in place. Let me know what you guys think.

I second Gary. Also, do you have any more pics of your finished stand? I will have to build a stand for my 280 and the footprint is the same as yours. Did you use 2x6s for the framing? Thanks.
 
I'm sorry I haven't been on in a while. I'm setting up my business and I've been a little pre-occupied.

Well what I ended up doing with the hole was I got a 8 x 8 x 1/2" piece of glass and placed it over the chipped hole and siliconed it in place. Now I have a clean surface for the bulkhead to seal to. I'll post some pics of it.

Yes I used 2x6s for the top and sides frame work and used biscuits at every joint. The bottom frame is made from 2x4s. The back, top and sides are covered with 3/4" plywood which really make the stand sturdy and heavy. The front is covered with 1x material to cover up the frame work.
I'm hoping to move the tank from my sun room down to my family room soon. I'm not looking forward to this move at all. The stairs are narrow and not much room for all the muscle I'll need to carry it downstairs. Wish me luck I'll need it.

Thanks
 
I'm finally moving the tank to its new location this Saturday. I'll have some new stuff to post then, sorry for the loooong delay. Things have been a little crazy.
 
I took a few pictures tonight of the tank on the stand. I also included a couple of pictures of how I fixed the chipped glass from drilling the 3.75" hole. Sorry it took me so long.

As you can see I took a 8x8x1/2" piece of glass, drilled it and placed it over the chipped hole. the glass in that area is 1.25" thick.
Today when I moved the tank I had enough muscle but I forgot to take pictures. I guess I was so concerned about moving the tank down the stairs and no one getting hurt. Everything went smooth and most everyone made it out unscaved. :lol:
