raunch Hey dbosman, yeah I thought it might be difficult to add media but I just have to make sure it's tiny media. I will probably be using a mixture of porcelain tubes, rocks, cut up sponge cubes, and carbon. So most of those are pretty tiny and shouldn't be a problem fitting them in. It will be more of a problem getting them out lol but not impossible besides I rarely change filter media, just give it a good wash every now and then. Thanks for the pvc )( idea.

dbosman@msu.edu If you have access to a table saw, cut two sections of PVC pipe and make a cradle of them like this, but rotated 90 degrees )( .

A drilled out tornado tube coupler will hold the bottles quite well.
You might look at Home Depot or a plumbing shop for O-rings that would fit over the mouth of the bottle, but atop the ridge below the threads. That would seal to the tornado tube coupler better.

My complaint would be how difficult it will be to put media inside the bottles.

raunch woah. you just blew my mind! I am totally doing the "hydroponic" idea!! I have been wanting to grow some mangroves and I can start them in the bottle. Good idea. Hmm, this is a whole new ball game now lol. Thanks for the idea.

AirstoND 1) Possibly a slit will be better, black PVC might make setup look "cleaner", although a clear bottle might grow algea and make it a nitrate reducer!

2) How about making top slits also and adding an airstone and going for a hydroponic plant setup?

Update

So I went ahead and built a more simple version of what I imagined haha. I drilled a hole in the cap slightly smaller than the hose and jammed it in and then temporarily duct taped it to do a test. I'll silicone it later or find something that will be waterproof and flexible. Also drilled four tiny holes for maximum sprayage! ha

I was surprised at the amount of current, it seems perfect for my 10 gallon. Of course when I add media (rocks, sponge bits, ceramic, w/e) it will slow the flow down a little but so far I'm pleased with it! Now just have to soak the sticker off so it's all clear and waterproof the bottle cap and bingo!

very simple design ha, so that means less can go wrong :P
OH and if anyone has any ideas for how to "pivot" this thing on top of back rim I would appreciate input! I am scratching my head trying to figure out a way that will look minimal and not crappy and on the cheap side (of course.)

Best way is to setup the plumbing the way you want and test. Only way to get a true measurement of what it's actually pump, especially if you put foam or mesh on the intake side, that is going to reduce flow a bit.

If you're intent on DIY, there are options. The first thing it test though is how powerful your pump is going up 2 feet. If possible, take the pump, rig up some tubing, 2 90 degree elbows into another container that you know the size of, eg, 1gal pail or something then time how long it takes to fill up 1gal of water pumped at the height your filter would be at. Then you'll get an idea on how much flow your filter would get it and if your pump is capable of pumping a decent amount of water at that head height.

In.a.Box you can build an inline filter using pvc with a 5gallon bucket using pvc pipe or hose as the overflow.

raunch Yeah I believe you guys are right and the bottles will be impossible to seal correctly. Also right about the pressure. It said on the water pump box it pumps up to 2 feet up. (It's one made for fountains) It would probably have enough power to get it up there but I don't think it would properly distribute out the spray bar.

Sooo, I will be redesigning and looking for things to make it out of. I thought about using tupperware containers (the ones with a rubber "o" ring and they snap shut) They are easy to find and cost effective and won't flex that much so I could probably seal a lot more effectively.

lol, so by the time I end up building all of this I could probably get a Zoo Med 501 canister cheaper. I just am not sure if it would be adequate for my 10 gallon. Says "Up to 30 gal" but I've also read that that means a 30 gallon tank if it were half full (for turtles) so that equals 15 gallons. Although I do only have shrimp so it's not like they put off as much waste as fish do.

Input? DIY or Zoo med 501? lol I'm all about DIY with EVERYTHING but sometimes it's just easier and less of a headache than building something. And since it's only a 10 gallon I don't need crazy filtration. Hmm
06-06-2012 02:25 PM
GeToChKn You also have to take into account if that pump has enough pressure to pump water up the height, then through the system to fill it and keep the pressure with the unit full so it can trickle out your spraybar. More than likely, it's going to pump a bit a water into it thats going to leak out the spray bar but not fully pressurize the system.
06-06-2012 06:04 AM
OverStocked I think you'll be disappointing with how hard it is to seal on the bottles. THey flex so easy and it is just going to be a mess. Sealing under pressure is even harder.

Also, if you put the pump at the bottom, it likely means you could drain the whole tank when the seals fail.

If you really want to diy a filter, it'll cost more, but I was happy using whole house water filter housings, pvc pipe and an inline pump. A submersible pump could be used as well.

raunch Yeah I guess it would look kinda bulky. Hmm.. I may have to redesign lol. Keep the concept and just do it with better parts. Or replace second bottle with just a piece of pvc extending from bottle one that will act as spray bar. Only then I'm losing the capability of having media in the second bottle too.

Weeelp, guess I gotta brainstorm more. oh boy
06-06-2012 04:48 AM
depech The concept should work. But it will looks bulky on a 10gallon tank. If you use a large bottle, maybe you can some how divid the interiar into two sections, one for filtering and one for spraying.

Here is an idea that you will have to research a bit.

My father made a toy for the grandchildren. It was 2 bottles of 2 liters each, connected at the opening. He partially filled the system with water and glitter. You would swirl the bottles and turn them upside down and watch the whirlpool as the water swirled from the upper bottle to the lower.
Here is my point: The system never leaked! There was some sort of tubing connecting the bottles. You might find it in a 'science for kids' sort of store, or a hobby shop. I have no idea even what to ask for. Good luck.
__________________________________________________ ______________________

Next idea: Wholesale irrigation store near me gives away damaged pipe free to whoever wants it. It may have been run over, bent or whatever. For the amount of good pipe you would use, (a foot or so) you might ask at places like Ewing, Horizon, Water Savers, John Deere or who ever is near you.
Yes, you then have to buy the fittings. However, they will not leak, and you can include something that will adapt to the tubing from the pump quite easily. Stock item, not DIY.
I remember making those "tornado in a bottle" things in middle school! Maybe it unconsciously inspired me to make this lol. I found a link to how to make them and then found this:

http://www.stevespanglerscience.com/product/1226

It is a small piece that connects the bottles together. Hmmm, this might be worth getting if it doesn't leak! The only other problem is you said silicone doesn't stick to plastic well so maybe instead of relying on only silicone maybe I can get a bulk head to attach at entry point of hose from water pump into first bottle. I would only need one and then just silicone around that to make sure it seals properly. I don't mind scrapping the water bottles, but I still want it to look like clear tubes so the filter media is visible. So pvc is kinda out of the question for me not because it won't work well (it would definitely be easy to make water tight) but just because I have a particular image of how I want it to look aside from function lol. I know I'm hard headed! I would prefer glass tubes of some sort but not sure what is cost effective and easy to manipulate. Back to the drawing board!
