Hi,
We bought a tank about a year ago, it is a aqua 320 and it holds 28 litres of water. We have had fish in the tank for about 6 months till we got into trouble (these were normal goldfish), the fish kept on dying, since the beginning of this year things are getting worse and we are at a point where our tank stood in the garage ready to sell on Trade Me.
After the second to last fish died 3 weeks ago I took a sample of the water to the petshop, the guy was really helpfull, he said that the ammonia level in the tank was too high and this needed to go down immediatley, we vacuumed the pebbles (stones) every day and the guy at the pet shop also gave us a little bottle of API Ammonia Detoxifier (which we used as instructed), but our last fish died about a week ago, he was swimming upside down and was very weak.
We cleaned the tank and was ready for sale on Trade Me, until we thought we would give it one last shot!
Now, the tank has been cleaned, the pebbles in the tanks we have halved the amount, because we think there might be too much pebbles in the tank that would cause more ammonia build up.
We are ready to buy a new fish, but we are wanting to make sure that we are doing our best to keep the tank clean and do not kill our fish over and over again, any advise you pro's can give us??? We are at a point where the funn of having fish is taking off, but we will give it one last try...that's why we need your help!
