Holly, you're disqualified.

After multiple rounds of voting, the April picture of the month winner is: Tyler E

Bump

There were four contestants that all had 20% of the votes. That being said, we need to re-vote!

Closes: May 7th 11:59 pm

I guess a re-vote.

Uhh. What do we do if there are multiple winners?

Post that .pdf file.

Hello All!

 

I want to build my own protein skimmer (60" tall x 12" body) and am looking for recommended books/websites to reference i order to figure out CFM air draw on venturi valves depending on pipe diameter and GPH water flow.  I would appreciate any direction, most of what I have found so far is high level calculus and really only need something a little more simple than this:

And on this note, anyone have any 12" diameter PVC they want to sell?

 

 

 

Is ρ density?

I believe that by looking at this equation that this is for fine tuning a protein skimmer or pump. Maybe calculating the density differential as you proceed up the skimmer? Which would be applicable for engineering a protein skimmer, but density, viscosity and a lot of these constants change from tank to tank.

For your sake and really all of ours who just want to turn a knob to raise or lower the proteins water level. I really believe you can resort to simpler methods. I've seen people even make these things out of Gatorade bottles and they work perfectly fine.

I think if I was going to design one, I would just make sure the water inlet and outlet have valves, the air pump has a valve, along with another huge valve to raise or lower water level with the ability to overflow more than you'll need. No one would want a protein that size to overflow. 

Here are the rules:

Show me your anemones. 

The person with the least number of fish will be put to the top of the voting list. I want us to stray away from the fish-anemone pictures.

@eclipse522 That's a good one.

I am glad to hear you joined PNWMAS. There are some pretty nice people here, that know way more than me.

That's cool that you make your own frags. I personally have never made any, but it wouldn't be a bad idea for how much I use them. You should post some photos about the process. I am kind of curious.

Siphoning helps, but a big one I also notice is flow and sand sifting inverts.

Although, if Cyano can survive. It will survive.

Cyanobacteria.

To be honest, I have had great results with : https://www.google.com/search?q=chemiclean

Although, a lot of people would say that it can be bad for the aquarium. It WILL get rid of it.

Just do a water change daily and run a bubbler for aeration. 

Fish looks a bit hungry. Feed them. Mysis, brine etc.

Never did any updates on this thread, but just to let everyone know...I am moving.

We will soon see the struggle of moving a tank this size, but eventually to be reincarnated into something better.

We have the technology.

March - Danlu_gt

The winner is: Danlu_gt

Sorry everyone, I think we found a winner. :P

Being April Fools', I thought it would be fit to have a picture of the month for Clownfish.

Have at it.
