farmchick Posted December 20, 2006 Report Share Posted December 20, 2006 Hey gurus :lol: As I have a vivid imagination and access to lots of free lime rock, I am wanting to make some rock caves for my malawis. With my imagination, lime rocks, slate and silicone I have the perfect picture in my head but I need to know if the lime will be okay in the tank. I know it will eventually wear away to nothing but as it will be free to me for the next decade or so, Im really wanting to give it a go. What are the benefits and/or pitfalls?

Ira Posted December 21, 2006 Report Share Posted December 21, 2006 Limestone is perfect for african tanks. It dissolves really slowly though, so probably would only bump the PH up like .1-.2. Quote Link to comment Share on other sites More sharing options...
peanuts Posted December 21, 2006 Report Share Posted December 21, 2006 i used limestone in my 6foot african tank and it has all been good so far the fish are really happy,only death was due to a fish fight, and the population is increasing all the time!!, and it raises the ph which is what suits africans (they love it) Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 21, 2006 Report Share Posted December 21, 2006 I used limestone in my African tank too to raise the pH. Quote Link to comment Share on other sites More sharing options...
Aquagold Posted December 21, 2006 Report Share Posted December 21, 2006 I have coral rubble 20-25kg sacks $1 per kg plus freight. Does the same thing. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 21, 2006 Report Share Posted December 21, 2006 I have a 1200mm community tank which is heavily planted and contains three large rocks of Takaka marble (also calcium carbonate) where I have created a cave in each one. The tank gets a 50% water change every one or two weeks if it is lucky. The plants seem to like it as it contains E.martii, red special and ozelot all with runners and the fish, including discus are quite happy. You will reduce the hardness created by removing it with water changes and reducing the creation of acid condition by the type and amount of food given.

Rocform Posted January 6, 2007 Report Share Posted January 6, 2007 Hi, you could try using a combination of real and synthetic rocks. go to this forum to see how the synthetic rocks are done. http://www.fnzas.org.nz/fishroom/synthe ... 17921.html Quote Link to comment Share on other sites More sharing options...
