my ammonia, nitrate and nitrate are all 0
i do 10% weekly water change without fail i treat the water i replace with tap safe, as it has a high chlorine content, this is the only treatment in my tank
i have a 1000/lph external filter
temp is 26
trigon 350 l
internal filter for flow and extra filteration
air stone on 12 hrs a day
i feed tetra crisp, bloodworms odd dried tubifex cube, brine shrimp.
ph is high at 8 but it comes out of my tap at that

First off - do a 90% water change.
Weekly 10% water changes are way too small - weekly water changes should be no less than 30% and 50% is better (of course, this depends on tank size; very large tanks don't need 50%.) Run air stone 24/7.
By the way, live worms, I feel, is asking for illness issues. I just don't trust those things - they are full of bacteria and parasites. Whether these harm the fish depends on a number of issues but I just can't justify the danger.
When did you last vacuum the substrate?
Something does not sound right - your nitrate is 0 and you have a well stocked aquarium with only 10% water changes per week? That does not sound possible unless you have an algae scrubber or nitrate removal filter. Are you certain the test kit is operating properly? Can you check it against a standard? or get another kit? Unless it is very heavily planted (is it?) and the plants are then suffering for nitrates, that number is very low.

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

Perhaps you could get your test results verified by a LFS near you?
The 0 nitrate reading does seam a little odd to me.

How large is your tank and how long have those fish been in there?
Generally, when someone says their parameter readings are all 0, it indicates an uncycled tank - most tanks have SOME nitrates (20ppm or less)
Agree with Cermet that the airstone should be on all the time - fish always need oxygen! Also agree that 10% water changes are inadequate - most of us do about 50% weekly - even more often if you are losing fish.

ok guys good spot there as checked water again and its 10ppm nitrate must have done something wrong not sure, but that still wouldn't explain whats going on? all the fish that died are new fish except the balloon molly who actuallynever looked right to be honest
