DanG Posted January 1, 2013 Report Share Posted January 1, 2013 Hi guys, This may have been a lesson learned the hard way, however I recently dosed my tank with a fungal multi cure (recommended dosage) and some of my Texas Holey Rock has turned green along with a few shells. As you can see the large piece has totally discolored and only a small amount on this small pieces. The large piece was never bright white, rather a dirty white, however green is really not a great look. Has anyone got some answers as to fix the problem or would it be a wait and see if it fades? Any suggestions would be most helpful. Thank-you in advance. Link to comment Share on other sites More sharing options...
Matmatmat Posted January 1, 2013 Report Share Posted January 1, 2013 What's in multi cure? Copper? Looks like the rock soaked up whatever it is.... Maybe bleach the rock? Then rinse and soak in wtaer with lots of dechlorinator. Link to comment Share on other sites More sharing options...
BRISSY Posted January 1, 2013 Report Share Posted January 1, 2013 Maybe spray it with a high pressure water sprayer? Link to comment Share on other sites More sharing options...
DanG Posted January 1, 2013 Author Report Share Posted January 1, 2013 Thanks for the responses. I might try the pressure wash first. Has anyone tryed the bleach idea. Once soaked in dechlorinator would it be ok to but back in the tank? Link to comment Share on other sites More sharing options...
lloydashton Posted January 1, 2013 Report Share Posted January 1, 2013 I would put it in a large bucket of water out in direct sunlight and change the water over daily. could take a few weeks though. Link to comment Share on other sites More sharing options...

PETFISH Posted January 1, 2013 Report Share Posted January 1, 2013 (edited) Fully submerge in a bucket of water and put in a cup of pool chlorine each day for a week ,cover bucket to aviod chlorine loss ,then soak in water with plenty of dechlorinator for a week.use fresh dechlorinated water each day for that second week.

fullycichlid1 Posted January 1, 2013 Report Share Posted January 1, 2013 Thats an expensive lesson! I have used multi cure before for white spot and it did the same thing to my gravel (black and white) I used the blue solution. I would be a bit weary about using bleach. I would try the water high pressure cleaner idea. Link to comment Share on other sites More sharing options...
tutters187 Posted January 1, 2013 Report Share Posted January 1, 2013 Multi cure is just fungus cure (acriflavine & malachite green) with methylene blue added, which I find odd because methylene blue is only good for fungus on fish eggs. It would have been the acriflavine and methylene blue that did the staining. Good luck trying to get that out. Copper sulphate does not colour the water.

DanG Posted January 4, 2013 Author Report Share Posted January 4, 2013 Thanks all for the comments. I used an Industrial strength pressure cleaner it looked like it took all the green off until it dried and I looked at it again today, where I found it be slightly green again. I wet it again and you could not see much of the green as per the pic. The piece was always off white with a few darker areas. Oh well I will put it in the tank and see how it goes. If it bothers ne too much i will give the bleach a try. Link to comment Share on other sites More sharing options...
tutters187 Posted January 4, 2013 Report Share Posted January 4, 2013 You could try soaking it for a couple days in some diluted chlorine Link to comment Share on other sites More sharing options...
