BK NW skimmers and Zeovit

[Bogg]

Holy s shinola!. Jeff those are amazing. Once again thanks for lookin out for me and the persuasion to keep my current kz skimmer, instead of getting the new bk. I don't know how you could document your experiece besides just relaying the message as to what happened with the bk and your coral health like you have. Thanks Jeff. Wow I think I'll scan through the pics again.

There's some interesting information in this thread, maybe it can get moved into the reef related forum for others to enjoy.

OK, done (hope I did that right )

BK does use some exotic metals in their skimmers though, right? Maybe their silicon-carbide bearings or "special alloy" shafts are leeching something that really pisses of SPS. Similar to how aluminum particles from phosgaurd irritates corals. I would like to know what an ionic vortex is though. Sounds cool!

Quentin, you're reaching with that one! A quick search on Google for "ionic vortex" brought me to this: Crop Circles Skeptics. Has reef keeping reached the realm of the extraterrestrial?

Yes, it's good to reach and stretch out once in a while.

BTW, I hope this discussion doesn't offend anyone using these systems and products. We're truly keeping an open mind and trying to learn more about various systems and techniques used throughout the hobby. And in usual SDR fashion, we're just keeping things light-hearted.

I just find it odd that people are only bringing this up about BK skimmer specifically. That's why I though perhaps it was something specific to the pumps. Because with regards to over skimming, I see with all other skimmer brands too. The smaller the tank, often times the more ludicrous the match. Yet, I don't hear people who put BM160 on 40g tanks complaining that their SPS starting dying immediately. Maybe they just never made the association.

Ionic vortices are utilized in plasma energy fields to help form the conical transporter beams commonly used by alien invaders to kidnap humans and animals for study, torture, and experimentation... according to a book entitled Secrets of UFO Technology. They are also believed by some to be one cause of crop circles.

(I'm not attempting to discredit or mock anyone's ideas here... this is just what I came up with in a quick Google search; I really didn't find anything on ionic vortices that appeared to have much scientific value.)

Seriously... I'm quite interested in this discussion... it's rather fascinating.

I think it would answer a lot of questions i have about this subject if GQJEFF would tell us if the other people that had problems were using ZEOvit as well. I don't remember ever hearing about anybody having a problem with NW skimmers before specifically, or hearing about people with SPS dominant tanks having a problem with overskimming. From what i understand is that it would take a HUGE skimmer and a SMALL tank to cause any real damage if the tank were SPS dominant as that is what we are shooting for isn't it? But when i re-read the ZEOvit guide today and saw that it was printed in black and white (without me knowing why they say this) it makes perfect sense the he would have this problem. It states that they are against the use of NW skimmers and prefer Venturi or injection skimmers to maximize the potential of the product there selling. Now i'm no genius or reef specialist but i'm sure Thomas Pohl knows what he's talking about and if he says his method has adverse reactions when using NW skimmers than i would say that was definitely the problem and not to look elsewhere. Especially when switching to a injection skimmer fixed the problem.

Here's where we're at.

This statement is logical:

"Overskimming a bac driven system such as ZEOvit may cause detrimental effect."

This statement is not logical:

"A large NW skimmer on a ZEOvit system will cause detrimental effect while an equally large 'injection' skimmer on a ZEOvit system will not have any detrimental effect."

All skimmers operate on the same principles, as a result, the above statement does not make sense unless there's something specific to NW skimmers such as a "ionic vortex" or the BK/RD equipment.

This is exacly what i'm saying. Your right it doesn't make sense why NW would be bad but an equal sized injection would be better. But, like i said, Mr. Pohl must have done his reseach to find this out so the person to ask would be him. I'm sure he could tell you exactly why. I know he posts on the ZEOvit boards so that would be where the question would be answered best. Or he can emailed directly here http://www.korallen-zucht.de/en/cont...orm/index.html

I don't doubt his research at all. I'm sure there's some reasoning behind it. Thanks for the info, Matt, I don't have much invested in either products so I don't have an urgent need to find out the answer, just a curious reefer. Maybe you or someone else can post any info here to satisfy curious minds.

I'm just as curious as you, i posted the question on the zeo boards so if i here any responses that answer any questions i'll be sure to post here.
