henward Posted January 27, 2013 Report Share Posted January 27, 2013 as subject any differents with the 3 above or do they all do the same thing? raise ph and make water harder? feedback would be great! Quote Link to comment Share on other sites More sharing options...
critter_crazy Posted January 27, 2013 Report Share Posted January 27, 2013 I think I used marble chip in my Malawi tank. The one you get from stone and water world anyway. Did the trick and was really easy to clean! Just gave it a stir up every time I did a water change - would settle really quickly also instead of being blown around and sucked up the filter like silica sand. Did give a quite a higher pH than oyster shell/grit which I imagine aragonite would do also. Tank with oyster shell sat around 7.2 while marble chip would sit closer to 8 Quote Link to comment Share on other sites More sharing options...
henward Posted January 27, 2013 Author Report Share Posted January 27, 2013 looking forsomething to permanently put in my sump not substrate. wtih in the bio media to raise ph, jsut ofund my ph ridiculously low, causing my arowana scales to chip. it has not lost its appetite nor being active, other fish are ok but realoly needs to be higher. so, i was thinking for space and efficiency, aragonite or oyster shell where does one get oyster shell or aragonite in bulk?

hovmoller Posted January 27, 2013 Report Share Posted January 27, 2013 Why not coral rubble? (stuff people use for SW tanks) Pieces are big enough for water to pass through and it's super porous so you can use it as a media and it would serve as bio media as well as contribute to hardness/pH. You can buy bags of it at HFF. You pay pr kg. Quote Link to comment Share on other sites More sharing options...
critter_crazy Posted January 27, 2013 Report Share Posted January 27, 2013 You can get oyster shell from most pet stores near the bird food (big bags usually next to the chicken food) Quote Link to comment Share on other sites More sharing options...
F15hguy Posted January 27, 2013 Report Share Posted January 27, 2013 the limestone chip would work well in the sump, tends to dissolve slower and the larger chunks wouldnt gunk up very fast at all Quote Link to comment Share on other sites More sharing options...

henward Posted January 27, 2013 Author Report Share Posted January 27, 2013 That chamber I will put it on will suit rough and high flow media.... I think coral bits is a winner! Thanks! Quote Link to comment Share on other sites More sharing options...
Ira Posted January 27, 2013 Report Share Posted January 27, 2013 That chamber I will put it on will suit rough and high flow media.... I think coral bits is a winner! Thanks! That's mostly what I use in my filters. The handfuls of oyster grit work, but they make a bit more of a mess if you don't have them in a bag. And I had bags of coral fingers and bits left over from when I had a marine. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 27, 2013 Report Share Posted January 27, 2013 They are basically all calcium carbonate so I guess best to use what is most convenient for you. Quote Link to comment Share on other sites More sharing options...
F15hguy Posted January 27, 2013 Report Share Posted January 27, 2013 hrmmm, Lime chip by far the cheapest, normally around $15-20 for a 20L bag Quote Link to comment Share on other sites More sharing options...
