Filter Sock GROUP BUY from filterbag.com?

[Newreeflady]

Hi guys-

Anyone interested in doing a group buy? The minimum order is 25 bags and I would be in for 7. Let me know if interested! I'd be willing to accept bank transfer via paypal and to put the order in.

These are the most recommended filterbags for longevity and function on RC- my generic e-bay bags were more expensive and are already falling apart. :/

I would be interested in 10. Shoot me a pm when your ready to make the order

 

[Newreeflady]

Sure thing.

These things have a lifespan no matter how good they are... I might just pick up more to meet the rest of the order if no one else is in need at the moment. - I'll give it until the weekend to see if anyone else is interested, then we can put the order in if that's good with you.

Best,
Angela

I use 10 micron filters.
a 10 micron sock on a 225 gallon aquarium reef aquarium = a sock that needs frequent cleanings. Like every 12 hours. I'm using the same 10 micron sock that I purchased 10 months ago. The right sock is practically indestructible.
I got the filter sock from a medical supply place in Rochester. It has a steel collar around it's top neck and it cost less than $5. These medical supply places are very common in metropolitan areas as they supply filters for dialysis machines (etc.) and they usually offer several different size filters.

Look in the Yellow Pages and make some phone calls. I'll bet there's someone in Ithaca that sells filter socks.

Hi Gary,

Thanks for the info on the med supply stores. But, i'm not such a fan of metal and I was going to stick with 100 micron filters actually. I tend to be a little forgetful, sometimes I change them every 2 days, sometimes 4- I'm not reliable Rust and/or flooding would be a concern for me. Luckily the all-plastic ones they sell online are about that price, too

Best,
Angela

to reiterate

to reiterate

the med supply places usually sell all sizes of filters- not just 10 micron.

If a steel collared filter was unsafe I would not run one in my reef aquarium.
Plastic is junk IMO. Your paying the same price for an inferior product.

 

[pimpinitup6969]

the rust isnt a concern in a reef aquarium gary? there is a local med supply store here and i have seen them there but was a little scared to get them

 

[Gary Majchrzak]

stainless steel in a reef aquarium.
think about it for a second.

I'll bet there's some submerged stainless steel somewhere in your reef aquarium RIGHT NOW. What about the shafts on your powerheads?

I don't think there's ever been a moment when there wasn't some SS somewhere in any of my aquarium systems...

 

[Newreeflady]

Why do you think the plastic is junk?

I believe bleach oxidizes stainless steel, and since I wash them in bleach, think I'll stick with plastic. I'm a polymer fan

 

[pimpinitup6969]

Yeah i know that i have had stainless in my aquariums before just didnt realize that they were stainless.... Thanks for the heads up Gary! I'm still in for the 10 when your ready and ill pick up a few from the med supply store to try too

 

[Newreeflady]

Sounds good, Pimp. (Love the name!)

 

[Gary Majchrzak]

bleach doesn't oxidize SS but I give up- you can place a fish in water but you can't make it swim :fun4:

 

[Newreeflady]

A bit testy?

I was reading at Hendrix Group (materials and corrosion engineers) that non-chlorinated solvents should be used to clean SS. " Non-chlorinated solvents should be used in order to avoid leaving residues of chloride ions in crevices and other locations where they can initiate crevice attack, pitting, and/or stress corrosion later on when the equipment is placed in service. "

Also, different types of SS may have different susceptibility to chlorinated solvents: "Stainless steels are susceptible to crevice or pitting attack in chloride bearing waters. Their behavior has been studied by a number of investigators. There is considerable variation in the percentage of apparently identical sites where attack occurs, when it occurs. It is useful to describe results in terms of the percentage of apparently identical sites where attack occurs at a given chloride concentration. Very tight crevices increase the likelihood of attack. Rough surfaces, sheared edges, scratches and similar imperfections also tend to increase the incidence of attack. Crevice or pitting attack also occurs under deposits and under biofouling growths attached to the metal surface.

Relative resistance can be described by the chloride concentration below which there is little likelihood of crevice attack occurring. The ability of chlorides to concentrate in some crevices means that occasional attack may occur at lower concentrations than shown in the following table. Nevertheless, the table provides useful guidelines.
Guidelines for relative resistance of stainless steels to crevice attack in natural waters

Alloy Chloride concentration below which
crevice corrosion is rare
400 series: crevice attack occurs in fresh waters
304SS: 100-200 ppm
316SS: 1000 ppm

The 4 1/2% Mo and duplex stainless steels are more resistant than type 316, but suffer varying degrees of crevice attack in brackish water and seawater.

The 6% Mo stainless steels have excellent resistance to crevice attack in seawater. " same source as above.

fwiw, some plastic also has problems in bleach.

not testy here

not testy here

you wash the filter socks in bleach. you don't soak the SS in bleach for weeks on end. I work with stainless steel in the real world

my heavy metal infected aquarium as of last week

FWIW I followed your aquarium thread and (quite honestly) I wouldn't run a filter sock on it, Angela.

 

[Newreeflady]

Hi Gary,

I'm not saying your tank is heavy metal infected, and you clearly show superiour husbandry skills compare to me (yep, me stating the obvious.) Just thought we were having a discussion and was a little put off by your comment- but then, things come off differently in type, so I try not to get to offended

Can I ask why you wouldn't run a sock on my system? Thanks!
Angela

 

[Newreeflady]

To add to that, maybe I should resurrect my thread. I really could use some help, probably. I have never had, in all these years, a super successful system. Just sustenance and slow growth, never a thriving system. Not sure how I haven't become discouraged, actually.

[Gary Majchrzak]

Can I ask why you wouldn't run a sock on my system?

sure. because of it's size and coral selection.

LPS?
Plerogyra and most Euphyllia are going to benefit from a less than perfectly clean environment. I would rely on skimming and regular partial water changes and skip the filter sock on a smaller system featuring these corals. JMO.

 

[Newreeflady]

Good point. I thought because it was 100microns it would not filter too too much. I started this because my last sump got super funky and difficult to remove grunge from because I wasn't running a sock- my sump now is a lot cleaner. The concern is that there will be degradation of debris in the sump with no animals to clean it up.

Thoughts?

[Gary Majchrzak]

clean sump is usually a good thing. Stir up any accumulated mulm when doing a water change. I do.

 

[pimpinitup6969]

i have never gotten anything but GREAT advice from Gary. Maybe you should try not running a filter sock for a little while?
