KH GH PH co2
Hi Folks: I use RO water in a planted tank - but having difficulties keeping
the water "harder". Tank is 54 gallons, with co2 injection. I'm using Seachem's Equillibrium but my GH/KH readings are very low. Any suggestions? I'm thinking of using half tap water and half RO water to maintain a more stable carbonate hardness. What do you guys do to maintain a more stable hardness/PH? cheers, Bruce |

I don't think that using RO water help you, you only reduce your carbonate hardness already present in your tap water. GB |

What do you guys do to maintain a more stable hardness/PH? cheers, Bruce You can use an aragonite based tank substrate like arag-alive by either using it as a gravel substrate or put it in a cheap nylon filter bag and keep it in an operating filter to keep the harness/ph up permanently (never needs replacing). I used a carib-sea bermuda pink substrate advertised as keeping hardness/ph up (meant for cichlid/marine tanks) and it only keeps general (gh) hardness up to the max (somewhere around 25-30 degrees general hardness) and doesn't help carbonate hardness (kh) at all so my next purchase will be for a different brand (like arag-alive) and substitute that for the carib-sea junk in my filters. Carib-sea seems like junk to me. One other thing you can do (use some caution just in case though, but don't be paranoid about it either) is safely use arm and hammer baking soda (pure) to raise carbonate harness and ph. Try 1/4 teaspoon for every 5 gallons I think (you all correct me if I'm wrong here, but this should be a safe amount), I think daily, until you reach the preferred KH then only replace the amount taking out with water changes. Good luck and later! -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) - WinPT 0.7.96rc1 iQD1AwUBQ4zSw62WfcjE5myzAQIWSQcAwrycdAvuhKdW8tosFa bkemg8jAxlyW/Q JodH6mkge8+7WC2mzLVYphC0bVK/V5ulnfZs7kf6oSDoemfzTTFipsotl2BuqDdL XB+1gEGH0URWIB3bR+8RR6fJVQeDzqZKz8Pns31WJl/zgY76L6OIJiv27gMchuH8 Rb5PUqp4NXh6w6Twf/0bYr0Yu21D8FNZrqC0Q6qfUeO+KVoXkHpBnIGer83qMR9S BDrjW9/v20xD5TCU7doaHpR5sCNtBcP/ZLkhvaxulhbDNk8PzuWfqyR+ZBpiwCiI BL4hXVkgrz4= =9NNp -----END PGP SIGNATURE----- |

You can also add some crushed coral which IIRC slowly dissolves and helps keep hardness and pH up. Gail |
