hey all i am wondering if there is anything out there that i can use to raise my KH other than wat the fish shopd sell as its bloody expensive.
My KH is currently 20ppm

This may help you- http://en.wikipedia.org/wiki/Calcium_carbonate Agricultural lime should cost much less than the aquarium stuff. Also- Quote: Again, the term "KH" screws up a moderately knowledgable person. "KH" is an obsolete term, and should be eradicated from the aquarium literature. Tests for KH measure alkalinity. quoted from this site- http://www.thekrib.com/Plants/CO2/alkalinity.html#0 I agree with the above quote for the same reasons explained on the site. Hope this helps you or someone out. |

Why do you think you need to alter your "kH".....carbonate hardness.... what's your pH? Most people don't even have to worry about their "kH"....... they just address the pH... and if the kH is high due to the inclusion of a carbonate buffer...like calcium carbonate... then it will become self-modulating within the AP process Then there's gH.... genral hardness.... again not usually a problem.... You'd really have to understand your pH and the relationship between them all.... In AP I don't think anybody really ever worries about kH... not as such In pond aquaculture it can a problem that requires attention... usually to moderate pH swings resulting from algae bloom Monitored more closely in grow-out systems with prawns, yabbies... crustaceans ... particularly when moulting As JD says... should probably filed in the darkest corners of the museum of antiquated and mis-understood terms... There's a section on the forum somewhere that discussed it.... maybe a lot of the older stuff hasn't been archived back yet. |

I could be wrong but raising KH could be done by adding just about any source of calcium carbonate right? Steve has written a post in useful information about alkalinity and hardness and pH which could be useful for you. Quickly, some inexpensive sources of calcium carbonate include; shell grit (get from a feed store often used for chickens) Oyster shells Shells Egg shells limestone Many people put a mesh bag of shell grit or oyster shells in their sump tank. I've actually used a mix of washed shells and river rock as my grow bed media. This is actually buffering my pH to 7.6 which is a little high for iron uptake but is good for the Nitrogen cycle. |

| Post subject: | Re: Raising KH |
so 20ppm KH is fine i thought it had to be around 60-100ppm to stop ph from cashing or is that a myth?? |

ph is perfect. never was too worried about KH, just add crushed shells to your system. Ph will ever drop below 7.2 to 7.4. may not show a big increase in KH as they are fairly insoluble. tried and true for the lazy AP'er |

if you can get to a produce shop or stock feed shop, they should sell shell grit for poultry. Get some of that and dump it in your sump or top up drum |

Mods, the two links in Rupert's post Rupe wrote: Ahh, thanks TCL.... here they are.... and there's lots more throught other threads... don't work, because it says ../phpbb/.. instead of ../forum/.. in the address.viewtopic.php?f=11&t=586 viewtopic.php?f=11&t=2852 (This must have happened when we changed temporarily to another 'forum' when the current one crashed once.) If you correct the broken links, please delete this post too. Thanks in advance selfless mods!
