Just like a glass test tube for a laboratory. You'd have to cut the end off, or use a glass straw to push the air into one end of the tube and let it flow out the other.

I see. Thats going to be a hard sell to get people to put skimmate back in their tank. Great thing to think through, though.

I wonder how much more junk you remove by skimming real wet?

My experience with washdown systems (huge RK2 skimmer and DIY) is that you need to run them at least several times a day to do any good.

Skimmate is generally a little oily so it wants to stick...

I would not use an airstone in the can if its anywhere close to appliances or tools, like in a laundry room. The salt WILL get out and eat your equipment alive.
Use a powerhead and your fine.

I have played with different heights (angles of attack by the blade) and it just seems to cut nicer- no melting on my homeowner style tablesaw.

The 3HP Powermatic at work has no problem:)

Is it chalky all the way through? If it was a thin coat and it was allowed to completely dry too fast, then it would be brittle.

Probably to simply cut algae growth. We did this to a lot of equipment at work. Really cuts maintenance down.

What kind of teeth, and how many? You could try using a solvent like MEK to dissolve the plastic. I would say heat it and scrape it off, but then you may warp the blade.

Carlos, I should also have told you that the pvc will become brittle over time, and may need to be replaced at some point. The glass obviously would not be affected by the ozone.

Jon,
I would test both acrylic to acrylic, and acrylic to glass.

I know when they set the 2.5" acrylic tunnels at my old job, they used a very wicked Sika primer to etch the acrylic first.

Ryan,
Is there a removable leg for your stand that gets put in after the sump? I'd be worried about having no support at such a critical point on the stand.

Hi James,
Could you explain "Nafta preferences"? Is this just that you prefer to use products made in the USA, or is it a term used in your industry somewhere.
Thanks,

You could always get a 2 stage Ranco controller, and let the Ranco control the chiller in both modes. Then have the AC Jr switch the Ranco only in over or under temp events like a control failure.

Nice work!
I have a slew of stuff that was "discarded", simply for lack of maintenance. A DI rinse, some new paint, and lube the bearings, etc. Good as new:D
