Ashy.a.p89 Posted August 14, 2015 Share Posted August 14, 2015 Hey guys!I have some Texas holey Rock that had been used in my cichlid tank for about 3+ years that developed some strange bright green spots on it that appear to be more of a staining and slight slimeyness rather than a fuzziness like some algaes (sorry about my descriptions. I'm great with fish knowledge but average with algae knowledge). I'm assuming it's either a type of algae or blue green algae. I have since sold all of my cichlids and taken the holey Rock out (of which I also intend to sell) and sat it outside with hopes drying out will kill whatever it is. But it hasn't made any difference! And the holey Rock is also going a very faint tinge of purple!I know flourish excel can be used at double dose to kill many types of trouble algae but it's quite expensive and considering I want to sell it, I don't think it's worth it.I have uploaded a picture in the gallery -> http://www.aceforums.com.au/index.php?app=gallery&album=536Does anyone have any thoughts or suggestions on what may work? I don't want to sell Rock to someone that's going to cause troublesome algae growth in their tank!Cheers Link to comment Share on other sites More sharing options...
Skippy Posted August 14, 2015 Share Posted August 14, 2015 Have you used any medications in the tank? Some of those will stain things they come in contact with blue. Link to comment Share on other sites More sharing options...
Chuckmeister Posted August 14, 2015 Share Posted August 14, 2015 Wierd, I would bleach it myself and see how you go. If its not in a tank then you wont have any problems. Give it a good scrub and wash with fresh water. Link to comment Share on other sites More sharing options...
Neil Posted August 14, 2015 Share Posted August 14, 2015 Also hydrochloric acid painted on neat then wait till it stops fizzing and washed off with the garden hose. Just wear gloves and don't get it on your skin .hthNeil Link to comment Share on other sites More sharing options...
Ashy.a.p89 Posted August 14, 2015 Author Share Posted August 14, 2015 Thanks for the response guys.Skippy, no medications have been used. My tank and fish were always really healthy. Water parameters were always good, although I never tested phosphates because I didn't have much of an algae problem and didn't keep plants in this tank.Chuckmeister, how safe is bleaching and then re-entering into a tank? Like I said earlier, I don't want to sell them and cause damage to another persons tank.and Neil, where would I get hydrochloric acid from? and once again how safe is it to be re-entered into a tank?I use Seachem's prime as my water conditioner, could I use that to remove the the bleach or hydrochloric acid? Or Seachem's safe? I need to get some of that so I can bleach and regenerate the purigen in my filter. Link to comment Share on other sites More sharing options...
Chuckmeister Posted August 14, 2015 Share Posted August 14, 2015 Bleach should be safe if you give it a decent scrub in fresh water.You could also consider using an oxy cleaner like napisan vanish as a spot cleaner. Again everything needs to be washed thoroughly in fresh water. Link to comment Share on other sites More sharing options...
yellows Posted August 14, 2015 Share Posted August 14, 2015 Sit it in some bleach for a day or two then give it good rinse then sit it in the sun for a week should come up white as then give it a good rinse before it goes in the tank Link to comment Share on other sites More sharing options...
