Ok, so went and saw our trusted qualified Aquariust today and he believes the 'itchy' behaviour of our fish is not infact ich/ick but, Gill Flukes. After much deliberation he sent us on our merry way with a Parasite Medication 'Serazin'.
As advised last night (when we thought ich/ick) I put the temp up in the tank to 30 Degrees Celcius. Today when we got the 'Serazin' we were told to drop the temp back down to about 27 Degrees Celcius, put the spray bar back on and have it facing downwards, do a 40% water change then add the 'Serazin'.
I did all of that and then left the tank to settle for around 3 hours before testing the water. Results of these were:
Nitrites: Between 0.10ppm - 0.15ppm
So, we once again have high Nitrites which has us scared. Our Aquariust tested our water earlier today and yes, the Nitrites were high (high than this evenings reading I am sure) however, it was believed that the 40% water change would fix this problem.
Therefore, what am I to do now? Normal advice for high Nitrites is to dose with Stress Guard (which I have here available) and throw in some aquarium salt (which I also have here) however, as I am treating the tank with the 'Serazin' can I use the Stress Guard and aquarium salt?
I feel totally bamboozled by all of this. I have had aquariums for over 20 years now and I have never had such problems. I am so scared of losing any of my fish so please, I need your advise and quickly!
