 | Raised ph in tank |
pos51  Fingerling Posts: 40 Kudos: 47 Votes: 4 Registered: 10-Oct-2005   | Hi there, First of all this is might sound stupid and probably has a simple answer but i cant put it right even after weekly 25% water changes. The ph in my tap water is 7.5, but in my month old tank its over 8. Could any one please give me a suggestion as to why this has happend and how to get it back to 7.5. cheers all.  |

Sometimes, if you have certain rocks or substrate (such as crushed coral) it will leach calcium into to water that will raise the pH. This is how pH is raised for African Cichlid tanks.

| pos51 Fingerling Posts: 40 Kudos: 47 Votes: 4 Registered: 10-Oct-2005 | thanks for the quick response. i have no rocks in there, and ive got around 2 inches of soft sand as substrate. as far as i know the sand is nothing special. |

If there is ammonia in the tank it will raise the pH. How long has your tank been up and running. Just going through possible scenarios in my mind, sorry for all the questions.

| pos51 Fingerling Posts: 40 Kudos: 47 Votes: 4 Registered: 10-Oct-2005 | hang on a tick, im just checking my water now. Im currently having a massive algae bloom of all types by the looks of things. ive taken measures but do you now if this would affect ph levels. |

| pos51 Fingerling Posts: 40 Kudos: 47 Votes: 4 Registered: 10-Oct-2005 | not to worry. my ammonia is 0, nitrite 0.6 think ive just had my spike (for cycle)from 1.6 and nitrate is 50 mg/l i think. the test kit is nutrafin and the nitrate test is really in desc |

Test the pH straight out of the tap again. Sometimes, municipal water will have wide swings in their chemial content that will affect pH and spawn algae blooms.

You could add some driftwood to your tank to bring down the pH, but it would be in tough competiton with what's raising it. Try this, thake some of your sand and put it in some treated tap water in a seperate container. Test it after an hour or two and if the pH comes up in that then you have your culprit.
