Thanks. That problem is solved. The next problem I'm having is the water level in the main column changes from time to time. I usually keep the bubble/foam line at the top flange. That usually works great. After a few days, the bubble/foam line drops to middle of the main column. What could be causing this? The outlet of the skimmer is not submerged in the sump water. I find that I have to constantly adjust the gate valve to keep the level in the same place. You check out how the skimmer is piped up here:

Can anyone help me with this problem?

next time you see this, can you try turning off the air and seeing if the water settles out at the same level you started with days ago? if it doesn't, your input to the pump may be getting clogged, or the becket getting dirty. when this happens to me, it generally means it's time to clean the becket.

Ditto on that here. I actually started using a filter sock in my sump just to keep my becketts and pump intake clear of debris.

Your water could be "flushing" out your drain. So the water level will rise, rise, then flush, and drop, then repeat.
hth

I don't quite understand what you mean by "flushing". Could you explain that.

i've found that using the gate valve to raise the water level back to where it was to be a very poor idea in these circumstances. if it is some debris in the line, it can work itself free and now your skimmer is operating at its previous flow. which means you risk a significant overlfow event which is probably not controllable by your waste shut off.
 
I'm not sure why you quoted me on that ;)

I agree, often debris does come loose, causing the water height to go back to where it was.

BTW, my waste collector has stopped overflows every time...no worries on that one, if anyone is doubting their effectiveness in this respect.
 
cr-2 reactor question

cr-2 reactor question

I just received a used cr-2 reactor in the mail and the fitting that is in the bottem of the first chamber is broken off right at the chamber wall. Can anyone tell me if this is threaded into the chamber wall? Looks as if it has been epoxied to stop a leak. I am hoping it isnt epoxied into the acrylic.
Thanks
Jeff

I've checked the input to the pump. It's not clogged. The beckett was cleaned a few days ago.

Last night I was cleaning the display. I had my hands in the tank so the level of the foam dropped as I expected it to. This morning, 14 hours later, the foam has yet to rise again. I did nothing else. I only put my hands in the tank. After 14 hours it hasn't come back to normal? That to me means something is wrong. Please help. I'm getting so frustrated.

MRC please step in to help with this problem.

What is that valve on the input to the beckett ?

That feeds my Calcium Reactor.
 
First off... Merry Christmas!

Secondly... I'm getting ready to get a pump for my MR2. I'm wanting to go bigger than the bare minimum, so I'm looking at the Gen-X PCX-70 or the Pan World 200PS. Am I doing right by getting more than the bare minimum? Which pump is most suggested if my main concern is noise? Any other thoughts?


Lastly... This thread has been split 3-4 times. Has anyone developed a FAQ and How-to that consolidates all this information?

I love my MRC equipment

I am new to this thread and would like to share my set up with you...This is my MRC Skimmer in action.

This is my fish room with the MRC Calcium Reactor on the second shelf. It's a dual reactor.

Great Thread! Thanks for sharing your knowledge with me!

Bump... I need to order a pump asap. Any thoughts would be appreciated.
 
rsteagall,

I'm using a Pan World 200PS for my return pump feeding my 210G display, 75G RDSB, and a 60G frag tank. It's quiet and I've had no problems with it when I've throttled it back in the past.

In the past, I had used it to feed twin becketts on my MR2 and was happy with the performance.
 
I'm still having problems with a fluctuating water level in the main column. As I mention a few posts back, the water level will be good for several days, the for no reason that I'm aware of, the level will drop in the main column. Can anyone help me with this problem please?
 
Newsalt, is your return below or above the water level? Do you have an ATO?

In other words with the questions above, is something affecting the return from the skimmer? If NOTHING is affecting the return, something in affecting the input performance.
 
The return from the skimmer is above the water level and I do have an ATO. For instance, it happened again overnight. Last night the water level was up to the first flange. When I woke up this morning to check it, the water was halfway down the main column. Can't figure it out.

I am having the same issues. After running flawlessly for a nearly two years, my MR-7 suddenly began to exhibit these exact symptoms. I have cleaned and re-cleaned the unit, checked the pump (Sequence 4300), removed the cotton balls from the air intakes, and tried resetting it as per suggestions mentioned here (i.e: Setting water level just below the Becketts and adjusting the intake valves.) Interestingly, many times, adjusting these valves will make no difference...the level will remain the same from nearly closed to wide open. A couple other things I've noticed is that the sound of the air intakes definitely varies. Also, the unit will function normally for a while once it has been turned off for several minutes then the bubble column will collapse back to the first riser once again. I have another pump and some new intakes on the way; hopefully this will solve the problem. Would appreciate some other suggestions though.
 
I'm not sure of the size. It's whatever fits onto the cup and waste collector connectors. My guess is it's 1/2" I.D.
