I used a sponge like that to remove some flatworms on my glass at one point. Shouldn't be a problem. I would only use a BRAND NEW one though.... one that has never seen soap.

 

If you read he package on new sponges most will say not for aquarium use.

 

LOL!!! I guess it pays to read I don't know that I ever would have expected an aquarium warning on any household product.

I guess I just lucked out with the one I got then (though I don't know what the problem would be that I avoided).

 

Many sponges are treated with antimicrobial agents to reduce bacteria growth and normal smells. I would be very hesitant to use one unless you know all the specifics.

 

It does not mention aquarium use and there is no treatment on the sponge it is just sponge some poly something

 

Try a brand called Dobie. It's old school, foam sponge with a plastic net scrubber on the outside. My old LFS swore by them for glass cleaning.

 

I use the same type of sponge to clean my glass as my wife does to do the dishes. Never had any bad reactions. The harder side of the sponge is great cleaning algae off the glass. I did rinse the sponge really well before I used it though.

 

Don't forget he said glass. Don't use it on acrylic it will scratch.

I use sponges to clean my skimmer cup but not on the tanks.

+1. Also I use a new sponge I rinse really well. I wouldn't use a old sponge.

 

A great sponge for glass cleaning is a new Mr. Clean magic eraser.

 

you cant use that on the inside glass tho

 

You can use the magic eraser inside and out. I believe futuredoc did an experiment a couple of years ago.

 

Here is the magic clean ingredient spec sheet from their web site.

OHBA is it just called mr clean original sponge? I want to try it.

 

This is what you should look for.

Not sure if you have kids, but this thing cleans with just water and the sponge. I saw somebody on here talk about it months back. I gave it a try and boy did it rip through just about everything. You can use it then let it dry out for about a month or so. It starts to fall apart if you use it any longer. Give it a try and let me know what you think.

 

Cleaning glass, sure, just as long as there's not microbial or smelly good stuff on it..
As filter media, it most likely isn't dense enough unless you're pushing A LOT of force with the water flowing through it and there's no alternate route for the water but THROUGH the sponge... even then it would clog fairly quickly I bet..

 

Thanks

 

Alright to to get a good answer i can use Mr Clean Magic Eraser in a tank full of fish i can just stick this thing in the water ?

 

My wife just text me a picture, she got me a twelve pack of beer and a Mr clean original sponge scrubber lol I can't wait to get home

 

Uhhh, guys?

Google melamine health risks, seems to be quite a bit more, infant issues, animal issues, even stemming from plastic tableware.

 

Hey Kung ~ I'm thinking that the quote "It is combined with formaldehyde by industry to produce melamine resin, a very durable thermosetting plastic, and melamine foam, a polymeric cleanser. Other commercial products containing melamine include countertops, dry erase boards, fabrics, glues, housewares, and flame retardants."

This appears to be a stable formation - and it appears to be the uric acid in the kidneys that transforms it from liquid to the polymerized stones that then cause the renal failure. I'm guessing that unless you're adding the pure, unpolymerized liquid form you're probably "safe." I'm reading the "durable" as chemically stable - especially as a plastic resin. Not that I'm going to eat it any time soon.

 

Sorta like the vinyl monomer in PVC - cancerous, unless in the polymer version.

 

Idk, it really makes cloudy mixture doesn't it?
Lol, people look down on dosing but now this is in the game? Sheesh!

I saw "causes renal failure" and stopped thinking about it (not to mention the fertility issues in animals)
Whether it's the purer form or this form, pretty sure you won't find it in the ocean?

Even Proctor and Gamble says formaldehyde if trace amounts in the magic eraser are found, they are "significantly lower than standards established by governmental agencies and trade associations"

Found this too
Melamine plastic will eventually break down into organic melamine and formaldehyde, but not fast enough to create a health hazard.
http://mentalpolyphonics.com/posts/review-melamine-foam-magic-erasers

But then after breaking down, all I can find is more of the same lol
Melamine is a man-made, cumulative toxin used in food equipment and packaging, as well as in an herbicide, which has killed thousands of pets and babies in years past and still continues to be a pervasive background contaminant.
http://www.thenhf.com/blog/tag/melamine/

Either way if it's inert or not, I'm sure it would break down faster in the tank, but as it's used it lets loose tons of micro-plastic, so the fish and everything would be ingesting it, and evidently that's the only thing on the label "do not ingest".

I love magic erasers, but I wouldn't use one in a running tank. The way they work is much like a very fine sand paper, little dust size bits come off with use. On the outside however, that would be perfect for salt creep and water marks.

 

What effect on the tank would the dust size pieces have? What would you recommend for use on the inside of the tank?

 

Oh well if I don't use the mr clean sponge I still got a 12 pack out of the deal!

 

LOL!

 

It removed an epoxy thumbprint from the black trim on my tank!

 

Magfloats work just fine, if it's REALLY bad, use a razor blade... be sure to rinse it off and wipe it down otherwise it'll just rust all over.
There's plenty of other scrubbers out there too.

Millions of little pieces of (possibly bad if ingested) plastic for the lose. I'm sure the creatures will thank you for not using it

 

What are the Magfloats made of? The scrubbing pads on the Mag need to be replaced as the wear down. What happens to this material? Razor blades are metal, so what happened to the metal that wears down during use? Blades dull as the sharpe edge gets worn down from use.
