Berlin Turbo Protein Skimmer


mr. wai

Hi all,
I have a 55g, but the cup is never full. How do I tune it up? There are bubbles coming up, but the cup only gets 1/5 full every other week.
I do have a lot of fishes and corals.
Thanks for your advice in advance.


IMO your skimmer is functioning properly, it's pulling out what you have. Meaning that since you don't have a large bio-load you won't have a large amount of skim gue.
One of the expert will chime in soon and give you some tips and tricks, but in the mean time please post more info so that the experts can quickly assist you.
They will want to know how long has your tank been set-up, what type of fish and corals do you currently have and how many, how long have you had your skimmer, what method of filtration are you using and have you done anything differently outside of your regular tank husbandry.
Post the above data so you can get quick advice.

How dry are you skimming? Depending on your system, you could definitely get more than that, but not necessarily. If you skim dry, or have a lot of build-up on the neck and riser, you aren't going to really get any skimmate. Do you usually have increased skimming once the cup and neck are cleaned? If so, you can try to skim a little wetter or just clean it more. If not, then that is probably how much the skimmer can do on your system.

If its a Red Sea Berlin its doing all it can do.. they are terrible skimmers and no better than seaclones..

I've used one at work and have been impressed with it for what the old berlins did. The new NW turbo isn't great, but it's not horrid. Still a few levels above a seaclone, IME.
