what does bump mean?

hahahhaah, it means that they have nothing to say and they are simply "bumping" the thread's order higher in the forum by posting a response.
 
sorry for the bump guys I need to get a couple things figured out before I can go on. I am almost ready for water but have just a few kinks to work out. so in a desperate plea, SOMEONE HELP!!!

ok so this is the dilemma. I had built a custom made fuge that I made out of glass. Well on the bottom to build more strength I added a piece of acrylic on the inside. When I went to drill the glass it cracked, but the acrylic did not. So then I ripped the glass off and left the acrylic bottom.

My question is, will it be bad if I just go with the acrylic bottom that is glued to the glass using your typical silicon?
Can you take a picture? It depends on a few things. A picture will help get you some answers.

Cavitation... yes it is where bubbles are inside the pump. A pump pressurizes a system. Sometimes if the pressure drops too much either on the impeller or in the inlet--which may be the case I was speaking to earlier--then the water may vaporize and become water vapor. Well pumps don't really handle a mixture of states like vapor and water. So what happens is the impeller cuts through the less dense vapor bubbles, speeds up for a nanosecond, and then hits the other side of the bubble where the water is. This causes a sound, reduces efficiency, can damage impellers over time, and puts a ton of microbubbles into your display making you the user angry.

If you have an air leak upstream of an external pump, this can also happen if even the pressures surrounding the inlet to the pump are sealed tight and sized properly. Air still enters the pump and does the same thing as cavitation.

I mention cavitation because the larger Magdrives tell the user to use larger diamter pipes upstream of the pump, but then reduce the inlet down to 3/4". That reduction in diameter--which causes the liquid to accelerate--can cause the pressure to decrease enough which may cause it to vaporize and do what I described above. hth.
 
WarEagleNR88, thanks for the info. I have heard that people have experienced problems with a magdrive CL but then I have heard of some not. Hopefully this won't be an issue. I have never gone the Cl route and already have the tank drilled. I will try to get a picture up of the fuge and the acrylic that I am using for the bottom.

On a whole I am aiming at getting the stand finished this weekend and staining it. That way I can finish the plumbing and finally get the system wet.
 
The only two things that are left to configure are:
1) If I can use a SCWD sideways on a closed loop without any problems.
2) I still need to figure out the Auto top off system for my sump.

Hi, DO NOT TRUST the acrylic to glass bond. While you may be able to use this configuration in a non pressure situation, ie acrylic dividers in a glass tank. A glass to acrylic pressure seam will never hold for long. I know, been there done that. hope this helps. Just glue/silicone another glass piece on the bottom.
 
Hey thanks for the info, I am already reconfiguring the glass piece and I am going to drill it soon. But for now let me post some of the pics of the stand and the progress I have made so far.

This is a pic of the stand and the hood,

This is the stand with the tank on it and lights on just for fun.

There is going to be a door on the stand but the piece I had somehow warped really bad before I could cut it so I have to return the wood and get another piece.

I am going to be plumbing the unit in the next couple days and will be taking some pics of that as well. I am getting pretty excited about the progress, I should have some water in there in the next two weeks.

Just a question, I am using a float valve to control the water top off, this isn't a classic failure that I don't know about is it?
 
Gee thanks. LOL yeah Tucson, Arizona for ya. Underpaid people with overpriced living with barely enough room to breathe. But thanks for noticing.

Nice Pics :)

I like all of the thought that whent into this project!

WOW--I just looked at your occupation.
Where do you go to Architecture school
I'm looking at schools right now haha
What tips do you have for future students by the way?
...sorry to diverge from reefs lol...i couldnt help myself :)

I bet it's the UofA in Tucson.

Oddiseus, are most of your arch classes in that nice building on Speedway? My wife went there while I was at DM but her classes were in the Psych building near Cherry St.

What do you think of that Mech building on the north side of Speedway ;) Now that's my kind of department :D
