I am new to the aquarium community . I have a 10 gallon tank with gravel outside filter, plastic plants. I got the tank going did quick start on the bottle it said you can put fish in right away , I have air stone in the tank clear water ph at 7.2 the water is hard so the next day I went out and got some hardy fish Zebra something all died, went to the fish store with a water sample they told me ammonia was high to use quick start for the next 4 days then every things should be fine, well 4 days goes by I did what they said again I buy some hardy fish put them in and bang all but one dies I got an api ammonia test shows ammonia at 1.0 , I do not have the ability to get a sponge filter from a seeded tank nor gravel from same so my question is what do I do now cape crusaders?
