Klaus,
can i just buy one of the ceramic bearings that goes in the front cover?
or, is the front and rear bearing the same?

(BK mini 200 with 1500RD pump) Gen2 i believe

 

[dahenley]

the bearing or bearing and front cover like this. either will work if they are available?

 

[Jeremy B.]

The bearing is the exact same whether in the block or in the impeller cover. The problem is that the impeller assembly is not meant to be pulled apart like in the photograph. The magnet assembly is is press fit onto the shaft at a precise spot, as is the impeller head. You can try putting it all back together in hopes that it will go back and hold and be ok long term.

Jeremy ,

I contacted Red Sea the manufactured on my tank/ stand and they made some suggestions for me to try and I was able to installed my 180 double cone skimmer without taking apart the black control box.
When I start out for the first few weeks what percentage (watts) do I use?
I attached the red hose from pump to skimmer , do I remove the black cap?
Thanks Ed

 

[Confuse]

I own a Double Cone 200 and I'm somewhat confused how to tune the skimmer. What do I set the percentage/wattage of the DC pump on? And why at a certain percentage?

And how do I adjust the wattage in conjunction with the pipe that you rotate to adjust the water level in the skimmer?

What exactly are you doing when you up the wattage of the dc pump vs. adjusting the wedge pipe.

thank you for that information.
I was able to remove the pinwheel without removing the shaft. (i miked the distance from magnet to the impeller for proper placement)
then switched the front and rear bearings. The front one had some wear, so after switching them and the o-rings, i re-assembled it and no more noise and vibrations.
thanks for those quick responses.

heres some quick pictures. (wasn't sure if you would want to see them. )

 

[Jeremy B.]

Perfect! Good work and glad to hear you miked out the distance from the end of the shaft to the magnet.

Supermarine 250 or 300 for my heavy packed 450 gallon system ?

 

[chuckbuc]

How much does ur sump water level need to be for a supermarine 250 or 300..whats recommended in sump water height from bubbleking

SM300 and 8"

 

[SchnitzelReef]

Just got my Double Cone 250 with DC pump. Wondering what water level works best. Also what percent you guys are keeping the pump at? Thanks. This skimmer is legit! SOO quiet!

Here's a pic from this morning

How many total gallons did u throw the 250 on shnitz

Try it in 7" - 7.5" sump depth and the pump at 35w and see how it runs there. However, I'd suggest keeping it there for a few weeks until the skimmer is good and broken in before tweaking too much with it.

I have it at 9" now and it seems ok. Any reason why u say to keep it at 35w? Why not keep it at 50w? I just had a skimmer stand built for 9". Will it not work at 9"?

 

[Jeremy B.]

9" is just fine to run this skimmer at, it's no problem at all. The Double Cone's and Super Marin's both have a pretty broad operating range for sump depth. 35w is a pretty good starting point to let the skimmer get broken in and not give it the tendency to overflow like a new skimmer can. Running it at 50w is not going to harm anything at all, I just usually recommend 35w and adjust the wedge pipe to where you need it and let it break in from there. I just don't suggest playing around with it too much during the break-in process to that you're not chasing your tail in terms of settings.

Ok. Thanks for getting back to me.

I noticed at 9" that my wedge pipe has to be almost closed to get good foam. Would raising the skimmer allow me to have the wedge pipe open more?

 

[SchnitzelReef]

 

[Jeremy B.]

At 35w and 9" that would probably be pretty close I would guess. Whether the wedge pipe is 95% closed or 95% open doesn't make a bit of difference, adjust it to where you want it and let it go. The high you go up with the speed of the pump the more you're going to need to open teh wedge pipe at the same height. Also, the deeper you set the skimmer in the sump the more open the wedge pipe is going to need to be and vice versa.
