GARF ( who started the whole rage of aquacultured rocks ) also repopulates reefs with corals from their farms ... if you asked anyone on here I am sure they would buy aquacultured corals first before wild collected specimins in a heartbeat. There is a bit of a conservationist attitude in this hobby already but you are right we should hang Steve by his toenails till he swears to never use such a caustic substance again :eek: :lol:

Cheers

Christy, what about CLR is bad? I thought it was mostly EDTA based (or some other chelation agent). Are there caustic subsatances in it?

LOCAL UFA!

Thanks Jonathan!

12-14% hydoxyacetic (glycolic) acid C2H4O3 (CAS 79-14-1); used elsewhere in household cleaners
3-5% sulfamic acid H3NO3S (CAS 5329-14-6); used elsewhere in swimming pool disinfecting and cleaning

3-5% citric acid C6H8O7 (CAS 77-92-9)

2-4% alkyl alcohol ethoxylate-acetate (CAS 68478-93-3)

2-4% proprietary detergent mixture


this is CLR, it is one of the more enviormently friendly cleaner in this class.

so by using it you are being more friendly than some of the other things out there. I can get some stuff from the ship that would have cleaned the tub in 3 min, but at 10 min if you forgot about it the tub might be missing also :eek:

Yeh I suppose, I was just thinking any cleaner that you have to wear gloves to use must be pretty dastardly to the environment. A friend of mine told me why it was so bad once but I can't remember. I just remember her being horrified that I mentioned it. Personally I have never used it, probably because if she ever found out she would kick my ass :wink:

I know at work we have airplane paint stripper, which is pretty caustic. I don't know if it would work that well on cement though. Acetone is another fairly powerful cleaning agent, we also use it to remove enamel paint.

:lol: :lol:

i used natural rain water to cure it didnt take long at all .
I thought i would let you know :smile: that..
