keep the Beckett as low to the box as you can no long pipe from the Beckett to the box it to will build pressure on the Beckett and the skimmer will not work as well.

how do u figure it is building up pressure?
i had my becketts as close to the box as they would go & when i put the long pipes on i noticed the foam was more stable & there was less turbulence, there for foam was more consistent.
what size pump did u use? i use an iwaki 70RLT on my dual beckett.

I tried dual becketts with the pcx 55...not enough IMO. I use a Panworld 200ps now and by running the pump full blast with the air valves open a little, I get a ton more tiny white bubbles.

Thanks Jackson.

The pump i used on my MRC skimmer Iwaki MD55RLT the best pump to run a Beckett
The long pipe is like a orifice it will create back pressure .The beckett skimmer works the best when there is no back pressure on the out put of the beckett and the gate valve on the box.

Steve- i used outside air for the beckett some parts of the Untied states are to cold to do this i all so the air that leaves the skimmer goes outside.One other thing that has work very well the air going to the Beckett has a air filter made for industrial used .I have ship some to Andy so he can try it,if you would like to try it ,you can get up with Andy

 

[steve68]

i see ur point but if u put the beckett as close to the box dont u think that would create more pressure cuz now the water is hitting the bottom of the box & pushing the water back up causing turbulance & back pressure?
maybee i dont have that problem cuz i have the 1.5 inch U tubes inside the box to help with the micro bubbles, when i did my mod i noticed a lot of back pressure when i used 1 inch U tubes & 1 1/4 U tube but water was flowing the same with 1.5, in other words i dint have to adjust my water level when i did the mod & that was my goal, at the time of this mod i was using single beckett right up to the box like u had mention & it worked great but the only reasond i put the long pipe on is cuz i had so much turbulance in the neck, maybee it was cuz i was using an iwaki 70 on a single beckett & when i put the secont beckett on i figure what the heck put the tubes on, IMO i really think that the bulkheads should be at least 1.5 to allow for better flow & no back pressure.
thanks for the input on the filter maybee u can PM me with a link.

im not trying to start an argument, i just like to learn from others & i think im going to do a test & take my tubes off & lower the becketts to see if it makes a difference, maybee it's all in my mind & i noticed less turbulence cuz now i am running 2 becketts on the same pump (there for less turbulence)

steve i have PM you.

So if I raise my MR-2 up out of the sump I will get before foam production?

[delusions]

Has anyone tried to mod their MRC calcium reactors to make them reverse flow? It seems that the current flow pattern causes the media to compact. I'm just curious if its possible.

 

[Creetin]

Delusions id liek to see that. I have the spray bar on my mrc cr2, and i dont notice any compacting.

 

[mungus]

Ereefic how is that recirc skimmer working for you? I am thinking of selling mine and getting the MRC-2 Recirc. Was it worth the extra $$$? Also I am using a pcx-40 currently eill this pump run that skimmer or should I buy a new pump also?

Thanks

Brian

 

[Ereefic]

It is working pretty well. I have been running 2 drains into it and i'm getting more skimmate than when I was just feeding it from the open sump.

Worth the extra money? I think so, but I also got it at a steal of a price.

You'll want to up the pump, don't think the pcx-40 will run the 2 becketts properly. I'm running a GRI 520 and it's doing well.

Ereefic--

Are you running 100% of your input to the skimmer via drain? Is it 100% gravity fed? how many GPH are you pushing through it?

I'd love to see a picture of your setup. I'm in the process of designing my basement setup and think that it would be a great option to feed my skimmer via this method.

 

[wonk]

I understand you can get a MRC modified to accept ozone, but how do you collect the air output to direct through carbon? is there a different collection cup cap or something?

I'd love to see a picture of your setup. I'm in the process of designing my basement setup and think that it would be a great option to feed my skimmer via this method.

I have a total of 3 drains (2-1" from 210gal, 1-1" from 45gal.) draining to the basement. 1 drain from the 210 and the 1 drain from the 45 going directly into the skimmer. My return pump is doing 3000gph at 10', feeding both tanks (3-1" drains) and is also T'd off to a growout/fuge (with a 1" overflow). So somewhere around 800-1000gph going directly to the skimmer.

I'll get you some pics of the setup later on.

 

[wonk]

Cool. Look forward to seeing the pictures. You mention that you are getting better-looking skimmate. It's hard for me to imagine that the pressure from gravity is comparable to a pressure-rated pump. Does the skimmer 'look' like it's operating as if by a pump? it just seems to me that there wouldn't be enough force via gravity.

 

[HippieSmell]

Wonk, he still has a pump on the skimmer, it's not solely gravity fed.

 

[Ereefic]

Hippie is correct. The drains are putting the water into the skimmer, the recirculation pump is pumping that water through the becketts.

 

[wrassie86]

Guys, for those of you using the mak 4 is the shaft in the middle of the prop suppose to be free turning/removable?Bought a used pump so was not sure if i should soak it or not.

 

[wrassie86]

After a quick call to pacific coast imports.The shafts are not removable.

Ereefic--

feeling rather stupid. I can't visualize how this would work. since I don't have experience with recirc skimmers maybe that's my problem. why doesn't the pump either push water up the display drainpipe or cause backpressure to the display drain?

I guess I cant see how you can have two non equal pressure inputs to the skimmer.

I bet when you post pictures it will make more sense to me.

So the drain from the display is going directly to the skimmer only to facilitate the dirtiest water from the tank?
