    Even though it's just a smaller nozzle perpendicular to the main outflow nozzle when I don't have the air tubing attached?

    Because closing a valve that I added to the tubing would cause backpressure against the motor. There's nothing on the powerhead itself to allow me to reduce the flow.

    It is a venturi line. It is designed as a suction line. IME physics usually wins out.

    http://en.wikipedia.org/wiki/Venturi_effect


    Backpressure is ok on a pump, they are designed to push against it. If the pressure is high enough, yeah it might leak out some through the venturi line. Honestly with a pump this small its a moot point. Your not going to burn up the pump if it is submerged and there is some water flow. I think you will be fine. No need to overcomplicate it.

    Yeah, I can overcomplicate things easily. lol Thank you for the reassurance.

    And I was at Lowes yesterday and saw their CPVC lines. You're right, it is much better for the spraybar. I didn't get any because they didn't have the right barbs for my vinyl tubing, so I'll have to run back to Home Depot to pick up the rest of what I'll need.

    Okay, I think I really need some help. I went to Home Depot today to get stuff for plumbing the return/spraybar... And I think I have stuff that I'll need to return.

    They only had brass barbs in the size needed for the tubing I have. It was after I left that I started to wonder if this would even be safe, given that brass is a copper alloy (and I have snails that I want in the tank). So, do I need to return those and somehow find a store with barbs in a different material?

    And then I'm not sure about the connector we found to attach the vinyl tubing to CPVC. The only thing we found that would fit both the tubing and 1/2" CPVC is this sharkbite reduction coupling. It looks like the inside of it is plastic, but would that be enough of a barrier?

    And they didn't have any CPVC pipes at all. :/ They had brass fittings, but that was it. (Seriously? Carrying fittings without the pipe itself? Ugh.)

    This is the vinyl tubing I have that fits my pump.

    I personally do not think it will matter if you use sch 40 PVC, sch 80 PVC, or CPVC, they will all have the same outside diameter provided they were manufactured to ASTM standards and not some cheap overseas knock off. If you would try, you will find they will all fit together. However, there are special transition glues to use if you use two different types of PVC (if you are gluing your connections). CPVC is not very common in most places. You might be better off looking for PVC (sch 40 or sch 80).

    The shark bit fitting is just as safe as all of the house hold plumbing lines in your house. They would most likely be the most expensive type of compression fitting on the market.

    You can find most of the fittings you will need on line
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I know the Lowes near me carries CPVC, and I checked it out the other day while I was there. It was definitely a different OD. When I hold a piece of 1/2" PVC, it feels too large for the tank. When I grabbed the 1/2" CPVC, it felt like it would work.

    My main issue for the CPVC was trying to match up the vinyl tubing to it. The 3/8" ID vinyl tubing is at HD, but not Lowes, while the CPVC is at Lowes, so finding something to transition between the two was tricky. The sharkbite coupling, while more expensive than I would like, seemed like an amazing solution until I thought about the brass.

    The shark bit fitting is just as safe as all of the house hold plumbing lines in your house. They would most likely be the most expensive type of compression fitting on the market.

    I was worried about the brass because brass is made with copper, and I have inverts in my tank that I don't want to poison. And yeah, I wasn't happy that they only had brass options.

    I was hoping to be able to install the new filter next week. Ordering plastic fittings online wouldn't really work unless I pay major money for expedited shipping.

    Okay, I think I found a source for plastic barbs: OSH. I'm going to call them in a bit to make sure they have it in stock, and see if they have CPVC. (Their website doesn't always reflect what's available in stores.)

    However, the sharkbite compressor still seems to be the best way to attach the vinyl tubing to the CPVC. Anyone else want to weigh in on whether this would be safe for inverts?

    It looks like you have lots of vinyl tubing. Why not just drill holes in that for your spraybar? Vinyl is soft and easy to drill.

    Then you wouldn't need a barb fitting. And just stuff a piece of foam into the end so the water doesn't all come out from there instead of your drilled holes.

    Spraybars usually have a neat row of holes to blow a steady stream of water. What you want is to diffuse the water for maximum flow but minimum current, so instead of a row of holes just drill a bunch of holes all over the tubing. That way the water would diffuse out in all directions instead of being focused in a stream.

    Like this (but with vinyl tubing instead of pvc pipe)

    Scrup mentioned upthread that clear tubing is prone to algae buildup. I had been asking specifically about airline tubing. I hadn't thought of vinyl.

    I had been starting to think about something like that. I remembered from Uarujoey's spraybar tutorial that he cautioned not to drill the holes too big. That got me to thinking, wouldn't deliberately oversizing the holes actually be beneficial to my goal? Either way, having lots of holes for water to flow through would likely be beneficial for me. I just need to hope that the snails don't decide to crawl up into them! lol

    Score! Found the nylon barbs at OSH! :D And I ran by Lowes to get CPVC for the spray/diffuser bar. That means I went to three different stores to get piping for this project.

    I have to apologize to you. The threaded portions of the PVC and CPVC do match. I got a simple 1/2" CPVC slip-to-FIP adaptor that will work with another barb to get water from the hose to the bar. It's a LOT cheaper than that Sharkbite adapter.

    And I have a few questions to throw out there.

    -What's the best way to clean the piping, tubing, and all the fittings once I'm ready to assemble?
    -I have teflon tape to seal the threaded fittings. However, even without the tape the fit between the nylon barb and the ball valve is very tight. I can only hand tighten it about halfway down. Would it be okay to use a wrench to tighten it further, or would that risk over-tightening and damaging the seal?
    -I forgot to get another clamp for the barb going into the CPVC (I have two for the barbs on either side of the ball valve). Since I'm not bothering to seal the CPVC either, would leaving that barb unclamped be alright?
    -And this is more personal preference... But should the finished spray/diffuser bar go down near the substrate (which will be Eco Complete capped with sand once I re-do the tank), or should it be up near the surface? Or something else?
