danilada Posted August 23, 2009 Report Share Posted August 23, 2009 I have not kept up with my strict tank cleaning schedules due to study, so have pulled my cichlid tank apart to give it a good clean! My question is: how do I get green algae off calcite rocks? -Currently using a scrubbing brush and hot water but leaning over the bath is killing my back, any-one use any-thing else? That is more faster. -This does work, but it took about 25 minutes to turn one green rock to a lovely white rock. I have a variety of sizes!

MarkLB Posted August 23, 2009 Report Share Posted August 23, 2009 I dip my rocks in a weak solution of bleach and then rinse them really well and dry them in the sun. Quote Link to comment Share on other sites More sharing options...
danilada Posted August 23, 2009 Author Report Share Posted August 23, 2009 Dolomite or Limestone? lol! Scrub to death or soak it in hot water, dry in the sun, and scrub again. Calcite and Limestone Quote Link to comment Share on other sites More sharing options...
danilada Posted August 23, 2009 Author Report Share Posted August 23, 2009 Hopefully tomorrow is sunny and will leave them outside while I am at work! I do not want to try bleach as knowing my luck . . . Good old scrubbing it is. Quote Link to comment Share on other sites More sharing options...
MarkLB Posted August 23, 2009 Report Share Posted August 23, 2009 I do not want to try bleach as knowing my luck . . . I know what you mean....I was dubious the first time I tried it. I rinse it until I can't smell bleach and then rinse it some more :lol: Easiest way I found was to leave them in the shower. Quote Link to comment Share on other sites More sharing options...
Deno Posted August 23, 2009 Report Share Posted August 23, 2009 I take my rocks out occasionaly and water blast them to be rid of the brown algae,a lot easier than scrubbing and it brightens up the whole tank nicely Quote Link to comment Share on other sites More sharing options...
Jennifer Posted August 23, 2009 Report Share Posted August 23, 2009 The weak bleach solution works a treat after just a short time soaking and when done properly it is completely safe. Make sure to use plain bleach without any added detergents or scents. Add up to 1 or 2 tablespoons of bleach to about 4 litres of water. After the algae is gone (usually after about 10 to 20 minutes), rinse the rock it in hot water until the surfaces feel clean and you can't smell any bleach (a few minutes). The chlorine comes out of the solution very quickly so the rocks will quickly be decontaminated of any chlorine residue. If you are still worried you can then soak the rocks it in a bucket of water with a standard aquarium dechlorinator. Or you could air dry it in the sun which also quickly breaks down chlorine gas. Any traces of chlorine that may be there will be completely removed and the rocks will be perfectly safe to place back in your aquarium. Believe it or not, like the pre-packaged lettuce in the supermarket, a very weak bleach solution is also handy for briefly soaking new plants that may have come from a dodgy source!

Thanks for a very detailed answer, I will try it this weekend. Quote Link to comment Share on other sites More sharing options...
danilada Posted August 23, 2009 Author Report Share Posted August 23, 2009 Best to treat the Algae prob than to delay it thou. ;-) The tank is opposite a sunny window and has some algae eaters in there, but I think every six months or so I may just have to give the tank a good clean myself.
