Hi All,
Just wanted to rack some brains for any possible answers..
I have a 190L Tropical Tank which has been established for over a year now, has a very mature external filter running and the internal filter (Juwel Trigon 190) also mature and running also with air pump in the tank.
Now i keep having problems with regular reoccurring fungus which i treat and seems to go away and then seems to come back around 8 weeks ish later?
Temperature is stable at 26*c, water quality seems ok Ammonia; 0ppm, Nitrite 0ppm, Nitrate range between 20-40 max and PH is 7.8
I change approx 30Litres once a week (Doing a deep gravel clean as i go) and feed very carefully with the amounts as not to over feed, and i clean all the filters in dirty tank water etc.
Am i doing something wrong here as i can't figure out why this keeps happening, it usually starts first on my black mollies then spreads to the other fish in the tank which are as follows; 2Black mollies, 6 Neon tetra, 4 harlequins, 2 clown loach, 1 bristle nose and 3 platys,
I haven't added any new fish to the tank in around 6 months and i haven't lost any either just seem to be battling the fungus!
There may possibly be an issue with Phosphates as i am seeing Black feather like algae which i have read could be linked to high Phos levels, could this have an impact on the fungus?
Thanks in advance!
