| Post subject: | High Nitrates |
My System is a 1000lt fish tank with one standard grow bed & one half that size almost 3years old , in the last couple of months I have been getting high nitrate readings continuously, I have changed about 50% of the water at least 3 times replacing with scheme water. I have lost about 12 nice native goldfish, only have about10 left. I am reluctant to get more fish until the water is right. I have had good growth from the plants in the system, so wonder what the best plan is to get the nitrate down from 160 plus. |

BUT -- could you set up a flooded and shallow tank and just grow "Duck Weed".. something that grows well and consumes the nitrates.. AND is useful as a by-product.. ( ISSUE - increases solar exposure and thus water heating ) The other possibility is to have a deep media somewhere.. and exploit the Hobby-Fish breeding thing of Anaerobic Bacteria, converting Nitrates to Nitrogen... ( If I read the articles correctly ) as commented elsewhere, I have a Cichlid tank that has not had a water change for years and whilst there is some algae on the glass, the vital readings are all near zero.. Difference - deep aquarium sand = anaerobic nitrate conversion.. .. . |
