livingart Posted June 16, 2008 Report Share Posted June 16, 2008 i think it will slowly leach into water may be able to seal with something though Quote Link to comment Share on other sites More sharing options...
Barrie Posted June 16, 2008 Report Share Posted June 16, 2008 whereas it may well leach but would it be harmfull? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 16, 2008 Report Share Posted June 16, 2008 It is calcium sulphate that reacts with water to return to gypsum. It is virtually insoluble and at worst would increase the hardness in your tank. Quote Link to comment Share on other sites More sharing options...
suphew Posted June 16, 2008 Report Share Posted June 16, 2008 Wont it also increase the PH? I know builders lime (kalk, calcium hydroxide) does. Quote Link to comment Share on other sites More sharing options...
livingart Posted June 16, 2008 Report Share Posted June 16, 2008 good for malawis Quote Link to comment Share on other sites More sharing options...
Luke* Posted June 16, 2008 Author Report Share Posted June 16, 2008 perhaps coat with epoxy like i read in another 'backgrounds' thread? also what sorta paint should i use/where to get it? (i think this answer might be in the other thread too) i'm making a betta biotype (well as close to as possible) Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 16, 2008 Report Share Posted June 16, 2008 It will not increase the pH but may make the water harder. Quote Link to comment Share on other sites More sharing options...
caserole Posted June 16, 2008 Report Share Posted June 16, 2008 Usless information time. It will definitely be ok with the fish as it was the original secret ingredient to curdle tofu > a long long time ago in China. It naturally occurs in the Szechuan(spelling?) area that had the big earth quake a few months back. Quote Link to comment Share on other sites More sharing options...
Luke* Posted June 16, 2008 Author Report Share Posted June 16, 2008 thanks for all the info guys.. incl the tofu.. :-? Quote Link to comment Share on other sites More sharing options...
Caryl Posted June 16, 2008 Report Share Posted June 16, 2008 Stu how come you can spell Szechuan but not casserole? :lol: I thought plaster of paris would break up in water. Isn't that what they use when you break a limb? Quote Link to comment Share on other sites More sharing options...
caserole Posted June 16, 2008 Report Share Posted June 16, 2008 Because dear Caryl I now use Firefox and have downloaded an on line spell checker that goes with it. :lol: :lol: Quote Link to comment Share on other sites More sharing options...
spoon Posted June 16, 2008 Report Share Posted June 16, 2008 Usless information time. It will definitely be ok with the fish as it was the original secret ingredient to curdle tofu > a long long time ago in China. It naturally occurs in the Szechuan(spelling?) area that had the big earth quake a few months back. but the chinese also see it necessary to put di ethylene glycol into toothpaste! seriously tho calcium sulphate is PH neutral hence its quickly taking over lime(alkaline) for use in lawns and gardens i would have thort it would crumble in water like sum1 said u dont get ur plaster cast wet do u and like alan said it could make ur water hard (though not like like concrete could) the other thing is u have to paint it with something if ur guna try it paint with an epoxy paint that way ur making sure Quote Link to comment Share on other sites More sharing options...
Ant N Posted June 17, 2008 Report Share Posted June 17, 2008 Be wary of things like "Cornice Bond" , "TradeSet 20, 45 , 90 "etc. They maynot be straight Plaster of Paris, but have additives to make mixture cure faster, this might harm fish.

Luke* Posted June 17, 2008 Author Report Share Posted June 17, 2008 So spoon i thought the epoxy was a clear coat shiny finish AFTER the paint? is the epoxy a paint too??? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted June 17, 2008 Report Share Posted June 17, 2008 Gypsum is probably the reason why the hills are falling over in China as well. Quote Link to comment Share on other sites More sharing options...
spoon Posted June 17, 2008 Report Share Posted June 17, 2008 u can buy epoxy paints as well or buy a water based epoxy clearcoat and mix in paint however some of the solvent based epoxies wont set with paint pigments in them but u could try a layer of epoxy then a layer of paint then another layer of epoxy Quote Link to comment Share on other sites More sharing options...
Luke* Posted June 18, 2008 Author Report Share Posted June 18, 2008 thanks, sounds like epoxy paint is the way to go, i assume this doesn't come as shiny either? Quote Link to comment Share on other sites More sharing options...
spoon Posted June 18, 2008 Report Share Posted June 18, 2008 i depends on the paint itself ive been using sand over it then painting over the sand its not shiny then Quote Link to comment Share on other sites More sharing options...
Luke* Posted June 18, 2008 Author Report Share Posted June 18, 2008 and then i assume you mean epoxy paint over the sand? Quote Link to comment Share on other sites More sharing options...

AMAZONIAN Posted July 20, 2008 Report Share Posted July 20, 2008 Hi All Be wary of things like "Cornice Bond" , "TradeSet 20, 45 , 90 "etc. They maynot be straight Plaster of Paris, but have additives to make mixture cure faster, this might harm fish. These products contain Mould inhibitors and are lethal to fish. Quote Link to comment Share on other sites More sharing options...
Luke* Posted July 21, 2008 Author Report Share Posted July 21, 2008 thanks Amazonian edit: and Ant N I just realised when rereading this thread that you also posted this info thanks! Quote Link to comment Share on other sites More sharing options...
