Bubble Master Skimmers more info wanted???

[mavgi]

any new color (darkness) of the skimming result.

on monday i will check and compare to my ER . from the picture that i saw i don't like so much the color of the skim.

that is what i got in 20 hour in my ER treadwheel and every day i need to clean the collection cup because it will split out if i don't do it. as i see the mesh on those pump are one layer and i believe if i add one more the bubble will be stronger and better skimming result but i think the watt will increase to and the noise with one layer it's quite but again i don't like the result i hope i am wrong.

here how my collection cup look every 20 hour .

Oliver,
Some folks here will desire to lower the skimmer water level.

your new mod looks good but, i dont see how adding the sliding tee is going to acheive a DRYER foam. It seems to me that it would only allow you to raise the water level.




Maximus,

You seem to be really good at wishing. Do you take wish requests? :lol:

Hehe, let me look into my crystal ball for the next modification!
I agree with Roland. I don't think the pipe is going to let us lower the water level.


Roland, the small pvc pipe lets me increase the water level. I need to increase it because the pipe that it came with is off now. When I took it off, the water level in the skimmer was a bit too low and produced really dry foam.

Creetin, what is your sumps water level at?

I also have great news. I fed heavily on purpose before I left the house. I came back 4-5 hrs later and the cup did not overfill! I think I will keep the water at this level for now.

 

[mavgi]

if the pipe will be longer then the water level in the skimmer body will reduce , if you modify that more longer and add a gate valve you will have the option for better adjustment but it's depend to what those pump pull out.

 

[LA-Lawman]

Skimmer height 19 7/8" tall. ID of collection cup neck 3 5/8"

cup is same OD of skimmer 8"

Do you have any shots of the foam on the 200?

Looks like this will make the skimmer worst, probably overflow???

..... the second shipment is with an adjustable Wateroutlet. The T-fitting is a little lower and ended much higher. Please look at the picture.

Thanks,
Oliver Pritzel

I didn't notice this earlier, but the T-fitting looks much higher than the first shipment model BM250, this would only make things worst. The T-fitting needs to be lower, so the water level within the skimmer body will be lower and skim drier. The higher T-fitting will overflow the skimmer and flood the collection cup.

..... Is this for all models? I ordered the BM150 and it will be here Monday.

Thanks,
Angela

The BM150 is already an adjustable exhaust pipe, doubt if there's any change on this model. The sample photo on ATi website is fully extended, I'm sure that one can lower the exhaust to get drier skimming.

Oliver do you know the time frame of when the next shippments of skimmer will be sent out? Iam on the second list and cant wait to get my hands on one. If you can let me know that would be great.
Thanks
Mario

My local guy has a BM250 coming to him on the next shipment for test comparison and he says about a month for him to actually receive it in hand. So, most likely will be arriving in USA about 3-4 weeks. Maybe USA will be getting in a shipment per month???

I just got off the phone with Greg at Reefgeek and he mentioned something I didn't think of. My sumps water level is exactly 9". I wonder if lowering the water level would have any effect on the water level in the skimmer? This is easier said than done as I cannot lower the level due to the Kent float valve. I also cannot put the skimmer higher as it would not leave me any room to take out the collection cup.

Creetin, can you tell me what your water level is inside the sump?

I don't think so. Since the exhaust pipe positioning is fixed, the water level within the skimmer is controlled by the position of the T-fitting... or in your case, since you took off the T-fitting, it is controlled by the height of the inner pipe, not by the sump waterlevel unless the exhaust is submerged underwater. If submerged, there is backpressure created on the exhaust, so if you lower the sump waterlevel, it will relieve the backpressure, which will lower the waterlevel within the skimmer.

 

[UCanDoIt]

1st Photo - Your exhaust is underwater, so there is some backpressure on the skimmer and probably raising the waterlevel within the skimmer a little bit.

2nd Photo - I would raise the bubble breaking level about 1/2 way up the collection cup. You'll probably have a better balance in skimmate. Just a suggestion.

That a poke at my cheapness?

Not at all. Guinea pigs get a $120 break on pricing, so it really doesn't hurt as bad, unless there's a problem with the skimmer design and needs to be reworked???

Right now, it looks like that the BM250 needs to have:
1. the stock exhaust pipe trimmed down so the T-fitting can be lowered, maybe there isn't enough length to lower any shorter or
2. the stock exhaust pipe be change to larger diameter and this might lower the waterlevel within the skimmer or
3. the skimmer body taller to compensate for the waterlevel height be too high. base on initial photos, I would think the new height would need to be at least 2-3 inches so that the skimming could be adjustable

Oliver,

Thanks for the information.

Will there be any external models in the future?

Thanks,

Jim

Yes, looking at a possible recirculating skimmer as well???

 

[Creetin]

Sang, My waterlevel is 6-7 inches, I raised me waterlevel to see, and it had no direct impact that i could see.
I dumped my skimmer shortly after a took that last pic and it was a little bit over 1 litre. So it easlit holds over 3 litres of skimmate.
Sang take the floss out of your riser and place it back on and tell me where your water level goe's to.

 

[Creetin]

Also i forgot to mention, I am pulling a little over 60 (About 62scfh)scfh with a dwyer airflow meter. I dunno if the airflow meter is bad though because i get 40 scfh with one of the pumps off. Doesnt make a diff which one i turn off i still get 40scfh, and when i turn both on i get 60 so i think my airflow meter is bad. Too bad i just bought it off ebay and it is supposedly brand new.

creetin

you read different because the back pressure on the pumps and not because the meter is not good i got the same problem when i try 2 pumps on my skimmer and when i turn the first pump the reading was high after i turn on the second one the reading lower on the same pump.

your new mod looks good but, i dont see how adding the sliding tee is going to acheive a DRYER foam. It seems to me that it would only allow you to raise the water level.

Ok, dont`t worry. The T-fitting only seem to be higer. Here are the exact modifacations:

1. The T-fitting is 1,5 inch lower, so the water level within the
skimmer body is lower and it is possible to skim drier.
2. The diameter of the acrylic-pipe is larger and thicker now. We
use a 60/50 mm acylic tube instead of a 50/44 mm acryly tube.
Please, look at the picture.

So, you can play with the skimmer, now. I know that some prefer a wet skim and some prefer a dry skim. The only difference is the quantity of water in the collection-Cup. But if you remove the part of water (cooking) you will have the same quantity of organics.

A disadvantage of a dry skim is that the foamtube gets dirty very soon, which has defently a bad influence of the performance of the skimmer. With a more wet adjusted skimmer you have a cleaner foamtube and this helps that a skimmer can work on a "higer level" for a longer periode of time. We made different comparisons and find out that you can remove more phosphates with a wet adjusted skimmer than a dry adjusted skimmer. We believe that this is a result of the mud on the inner side of the dirty foamtube. The mud seems to have an influence of the quantity and quality of the skimmable dessolved organic substances.

Will there be any external models in the future?

Our plan is to come with external models in 2-3 months.

@Maximus

Could you please explain the add on kit?..... I wonder if lowering the water level would have any effect on the water level in the skimmer?

If you lower the water level in your tank is has no influence on the water level in the skimmer. The water level within the skimmer is controlled by the position of the T-fitting. But a lower water level has a small influence ( - 5-10 %) on the performance of the pumps. I am sorry, that our pumps have too much power. Normally, you should have the same results as Creeting. But you can simply reduce the power of the pump, if you reduce the diameter of the treadwheel. The diameter should be 46mm or 1.81 inch. If you cut it a little to 45mm or 1.77 inch on one pump it should be perfect. But be careful, you can`t glue it again if you cut too much. Greg has no mateiral for replacement at the moment. We will sent all this things with the next shipment.
The add on kit is a t-Fitting and a ball valve. I will show pictures on monday how to use it.

@Creeting

please make your messurements after the silencer and use a thicker tube for the connection with the flowmeter. This is important . There is no high backpressure on the pumps, because the wateroutlet of the skimmer is large enough for both pumps. We only got bad results, if we connect both Air- intake tubes with a T or Y-Fitting. That is the reason why we go directly in the silencer with each pump.

Have a nice day.

Thanks
Oliver

I just got the BM250 and was wondering if anyone else is a little worried that the pumps have no ground plug on them?

Ok, I don't understand what is wrong. I woke up today and found that the skimmer was overflowing. However, a new, potentially dangerous issue has arised.....water splashing underneath the stand What happened was when the cup was full, the holes on the lid of the cup kept spewing water through them. Because of this, I had water all over the stand and estimate that I lost around 1/2 gallon from it. I believe that either the pumps are much too powerful for the skimmer or the water level is much too high. This is strange because the water level was at a good height last night. I am at the end of my patience and do not know what to do.
