NirIte level: zero
NitrAte level: 5
pH: 7
Temp: 72oF
3 airstones
110 litre tank (30 US gallons)
weekly 60% water change
Two Fluval 3+ filters which each filter 700 litres per hour (185 US gallons per hour)
3 fish (blackmoor and 2 fancy goldfish) and a hillstream loach
Nutrafin Aqua Plus added as appropriate to each water change
Fish fed on sinking pellets, bloodworm and occasional peas
Tank has been running a year - all fish are just under a year old too
A week or so ago my other blackmoor, Blueberry, got sick and died
After blueberry died, I put the remaining fish in another tank. In the main tank I removed a lot of gravel, so now its about 1/2 to 1 inch deep and cleaned it as best I could. Also took plants and ornaments out and washed them (in dishwasher, no detergent), put new airstones on, cleaned filters as normal (rinsed in tank water, replaced half in each with new filter medium), did an 80% water change, and added salt to 0.1%. Then added the 3 fish back (loach kept in unsalted other tank)
The fancy goldfish seem ok. Sharon the blackmoor was a bit listless, resting on the bottom, but thought maybe that was due to stress and perhaps being a bit poorly - thought if i left her alone she might perk up. Then noticed she had one eye which had turned white/opaque, and she seemed to have a small cyst just behind her eye too. Thought that as water and tank were in good condition and there was 0.1% salt that best to leave her alone and keep an eye on her. She was still listless but would swim about to feed so had my fingers crossed.
Today she's taken a real turn for the worse - other eye now also going cloudy - cyst is no better (might be a bit bigger), fins clamped, doesnt move very much (in fact she was jsut floating about in the tank with the currents from the filters so moved her into a small tank to keep her stress levels down), floats on her side or upside down, seems to have lost her black colour quite a bit, and scales are raised.
Am assuming this is dropsy and probably not much i can do for her....?

The water conditions before both moors got sick were fine, but there was probably too much gravel (although i gravel vac at each water change...).
I have now added more salt to the main tank to 0.2%, but Sharon is in a different tank with the 0.1% salt (was bit worried about adding more salt as she's already so poorly)
Am getting really worried that i might kill them all off! And its so awful to watch. But not sure what else i can do? I live in UK so getting hold of some meds can be a bit problematic.
Please, if anyone has any ideas what's going on with my tank i'd be very grateful for any advice - it would just be terrible if the last two fish got poorly too.
What on earth am i doing wrong?
