![]() ![]() This means that along the edge that is to be cut only slide it off enough that the blade cleans the supporting bench/table underneath. I have found that it is critical to have the sheet well supported. They do make a blade specifically for cutting acrylic but at a premium price and since I don't do this very often. I used a regular blade to cut the sheets. A thinker sheet is more forgiving but not impossible to crack. NOTE: I have found when cutting acrylic it takes some practice. It is VERY important that they are smooth and as flat as possible on all edges the will meet another sheet. Now I cut out all the pieces one at a time. Next, I took and marked down all the pieces I wished to cut on my sheet. If for instance you wanted to use larger bulk heads you would have to enlarge the measurements to meet your needs. Now this is the step where you would adjust according to your needs. This really helps to get everything going. First thing I did was to copy the dimensions of my current overflow box. Now that I had the supplies all lined up it was time to get started. Not a huge amount of savings but hey I can custom make it! The use of a miter saw/ and circular saw/tape measure/drill (already had these as well) PVC to finish plumbing on everything.Ī set of sliding wood clamps preferable with rubber boots on the ends. Luckily for me the place where I work was getting rid of some old storm windows which happened to be 1/4 thick acrylic sheets! I won't include the price of sheets in my total cost because I honestly don't know how much it would have cost to get.Īcrylic sheet: Freebie/zip/zero/zilch/nadaġ 1/4 Hole Saw: $10 HD (already had one so nothing for me.) They don't need to be as thick as what I used but thicker then what you could normally find at HD or Lowes. Now the hardest part of this would be finding acceptable acrylic sheets. To start this project off first we have to gather materials. Now of course I could go buy an overflow and it would of ran me about $80 new from the store. The task at hand was to add another 75 gallon tank into the mix with the current sump and other tank. Well after several months it is time to expand the setup and split the Discus up since there are now some clear fast growers. It worked great on my 75 gallon and the Discus have been very happy. I had original setup a sump (Link found Here) with an overflow box I got off CL. Then you just need enough power heads to get up to 1000gph total system movement.It is about time I posted another one of my DIY adventures! A few weeks ago I began working on an overflow box. Don't increase the pipe size on a small pump such as this unless you're going to pipe it like 20 feet or something crazy. Pipe it all the way back to the tank in 1/2 inch pipe. That's something a lot of people are doing to gain a flow control advantage instead of just allowing a pump to run wide open. If it's too much, you can always build a bypass Tee into the return line down in the sump and just divert extra flow back into the skimmer compartment or refugium. A Quiet One 2000 would provide about 200gph at 4 feet head pressure. I've never used a Quiet One pump, but a lot lof people have good things to say about them. That's typical tank height off the floor and your return pump has to fight that vertical rise as well as some elbows and assorted fittings along the way. Even those would be overkill, but it doesn't hurt to over-design the plumbing for the pump you are going to use.Īssume the pump has a head pressure of 4 feet. If you just want to move 100-150gph through a sump - all you need is 3/4" drains. If I were you, I'd shoot for 1000gph flow and circulation - combined between the sump and the in-tank power heads. You'll need some powerheads to make enough water movement in the tank. So for a 55g tank you want between 550gph - 1650gph. I've seen and had LPS and softie tanks with 30X turnover. So, you want about 90 - 150gph going through your sump.īut you want at least 10x flow/circulation rate in your tank. Typical sump movement is 3x - 5x the tank volume per hour. Here is a bulk head flow chart that you can use to size it all. I always buy 1mm larger than suggested by the bulk head manufacturer. They come in every size with increments in mm. Buy the diamond coated hole saws in the correct size for the bulk heads you select. ![]() But they are cheapo as hell and they work perfectly. They are sent in tiny boxes with chinese stamps. They are from hong kong and take a week or 10 days to arrive. Richon Tools dot com is a great place to purchase hole saws for a couple bucks. FlexPVC dot com is a great place to purchase bulk heads cheap. A 1" bulk head does not fit in a 1" hole. There's a hundred videos on youtube for how to drill a glass tank.īuy your bulk heads first. ![]()
