Ghetto Rig

That $h1t is awesome!!!

It produces pretty dark skimmate too. A little wet but super dark. I pretty much just cut out the bubble feet at the bottom and drilled a hole through the bottom center to hold the airstone. Using a regular topfin air pump rated for 80g with both air outputs feeding the same airline. The top I have a FPT to 1/2" barb adapter with vinyl tubing leading down to an empty crystal geyser bottle. Oh and I have epoxy-coated magnets inside the bottle and outside the sump to keep it in place.

I think the elongated cone of the Pellegrino bottle is a perfect fit for this application :dance:

I agree. I feel like doing the same. Do you have any blueprints on this? I think reef octopus is looking at your design. LOL

Do you have any pics of your build process on this? I might actually use this until I get the skimmer I want.

Don't really have pics of it being built because I literally just threw it all together the day I laid eyes on the bottle but the bottle itself you'll understand when you see it. Most plastic bottles have little bubble feet on the bottom for stability. I just cut out those bubbles, making sure to preserve some structure and a little disc at the bottom of the bottle. Then I drilled the bottom using maybe a 1/4" bit (in hindsight, it might be better to drill before you cut off the bottle legs).

If you get a Lee's limewood airstone (hell any limewood airstone would work just as well), it comes with a little plastic plug for your airline in the chunk of wood. This is what I superglued into the hole at the bottom and attached the airline so it comes out and up the side of the bottle. Rubber bands will degrade with time so I actually supplemented it with a zip tie at the neck but there's no reason why you can't just use zip ties to secure the airline just don't pull them too tight.

For the top of the bottle I actually had to use two piece of PVC to convert the 3/4" screw top to a 1/2" barb elbow but you can probably get a one piece fix like this:

Then I used some 1/2" vinyl tubing to connect the elbow to a crystal geyser bottle I have sitting just outside my stand since I have literally no room inside the stand. For an air pump I use a regular Top Fin air pump. I read that for air stone skimmers the higher the rating of the air pump the better it'll run because there's a lot of backflow from wood airstones. I used an airline T-Fitting to utilize both ports and a check valve to make sure water can't go the other way. The pump has a dial regulating air flow but I used a 2-way control valve anyway to make finer adjustments.

That's basically it. The total list of materials:

-1 Plastic Pellegrino bottle with bubble feet cut out and hole drilled in the bottom
-2 Plastic Crystal Geyser bottles for skimmate
-3/4" FPT -> 1/2" barb elbow fitting (Home Depot kept arguing that the threads are different so it wouldn't work but it works fine for me with little to no leakage. You could probably seal it up too if you wanted)
-1/2" vinyl hose to transport skimmate
-Limewood Airstone (I used Lee's but you can use any kind really)
-Airline tubing
-Air Pump (higher the output the better)
-Airline T-Fitting to utilize both ports on the pump (OPTIONAL)
-Airline Check Valve for peace of mind
-2-Way Airline Control Valve (for air flow adjustments)

I had most of this stuff except for the barb elbow and a fresh limewood airstone so I paid maybe $10 (got the airstone two-pack so I had a replacement handy)

I'll grab more pics of the setup.
 
Okay here are some pics:

The whole setup. Can see all the airline pieces I used and that the airstone is anchored at the bottom of the bottle. This is pretty important so that your airstone isn't moving around.

Closeup of the skimmate. I have 2 empty bottles and I just switch bottles every week or two.

The bottle fittings at the top. It took me two pieces to achieve the conversion because the selection at Home Depot is lacking but you could probably find a 1 piece solution online. What you're seeing is a 3/4" -1/2" FPT/FPT and then a 1/2"-1/2" MPT/Barb elbow.
 
I wish I thought of that.....

But aren't you worried though of the collection bottle filling up if the skimmer goes haywire since you have no collection cup at the top of the skimmer it would worry me a bit with the collection bottle on the floor outside the sump.....

When I first put it in, it put out like 1/3 of the crystal geyser bottle in a few days but after the first week, the skimmate production has slowed and become much darker. For the bottle to overflow, the air pump would likely have to go completely berserk or it would have to start pumping actual water which is completely unrealistic. At this point in time with the current production speed the skimmer would take a while to completely fill a bottle and with the wooden airstone having dimishing returns it would likely take longer and longer to fill a bottle if I didn't replace it every month or so.
 
Aaaah DIY skimmer days! I do not miss coming home each day wondering if I will find a big puddle on the floor!!!

I ran a DIY drink bottle skimmer for a while but I gave up on it as it was too temperamental (either no skimmate or overskimming and risking draining my tank!)

Good on ya for your ingenuity tho!

I think the Pellegrino bottle I chose is pretty good for not overflowing my collection bottle. I've spent many a time just staring at it at work and can't really imagine drawing out enough liquid to flood. The MAME skimmer uses a pretty similar concept and I think having a longer skimmer decreases the chances of a flood simply due to the fact that the bubbles have to rise fairly high to even make it to collection. Will definitely keep a close eye on it in the coming weeks though!
 
Anyways.......AWESOME THREAD!!!!! There was so many different things that I wanted to comment on. I think that RC needs to implement a "Like" button or a "+1".

I have done my fair share of rigging stuff in the past but nothing of this caliber. Hats off the many creative minds involved with this thread!!!

HIGH-OUTPUT t5 fixture.. found a polished reflector from some kind of gymnasium light.. poorly/oddly shaped cut boards for ends/light holds.. push on wire connectors for t5 sockets


Im sure I have worse too just not interested in going through mess of pics

chain in the picture is extra support for poorly built stand


oh yeah http://www.youtube.com/watch?v=mjfox0KkGVo
