Skimmer collection mod...
Skimmer collection mod...
Well I finally got the screws and finished my mod of the collection cup system. I'll call it
Ode to Weatherson II.
This first pic is the bucket assembly.
Here is the underside of the lid. This is a 6 gal. bucket and the long pipe is on the supply side and will create back pressure and shut down the skimmer when the bucket is full. This should substantially decrease my floods!
Here is a shot of the carbon container. I use this to reduce odors in the tank room. It works great and I know that this is totally overkill but I used this project to warm up for the reactor I will be making soon.
This is the carbon container lid. REAL DIY! That's what happens when you use hand tools but it doesn't really matter. The slightly square side helps me line the cover up with the screw holes as well as keeps the unit from rolling off a table.
I switched to stainless screws since I was quickly fed up with the zinc ones I have been using. They bite. These screws are unfortunately only 18-8, which is commonly available in the marine industry but not nearly as good as 316. I have tried to source 316 screws but I haven't found them at a reasonable price. I can get these 1/4" x 20 screws for $15 per 100 so that made the decision. We'll see how they perform.
I also was not happy with the flat rubber seals I have been using because they don't compress enough to make a good seal. I tried sourcing gasket material but that proved difficult so here is what I came up with at Lowes. These are actually the same material used for schedule 80 bulkheads, only a bit fluffier.
They compress nicely and have already proven much better than the rubber. Now I will have to see how long they last.
Here is a pic of the collection cup valve. I use the double ender so that I can pull off the entire collection cup without spilling skimmate, wash it out and do maintenance on it. I like having the valve removable so the whole unit will fit in the sink, as well as being able to easily replace it if needed.
Going back to the first picture of the bucket, I want to point out that part of this system is a second drain hose that attaches to the first one, thereby making it long enough to reach the sink. This enables me to disconnect the bucket and run the line to the sink so that I can wash down the collection cup while it is still attached to the skimmer. I use a water hose from the sink, spray down the collection cup, and that allows larger quantities of water to flow through the drain line into the sink.
I also want to point out that the one major disadvantage to this collection cup is the large number of screws. This requires some time to remove any part of it and that is why round cups with twist-on flanges are a better idea. BUT, I don't have a CNC machine to make one so I go square!
