Multiple Deaths

Don't have enough experience to help with your problem Tom but just wanted to say sorry for your losses. Sandra

Thanks Sandra.

Hi Sue No new fish introduced to tank for at least 2 months. It is just live bearers that have issues and it is fish born in the tank that are dying. I used to have coral sand in my filter to harden water as we do have very soft here in Scotland however I took it out some weeks ago as was going too much other way. I noticed that my Ph Gh and Kh last few times tested have started falling 6.8, 107 and 36ppm respectively yesterday. Ph was 7.6 at one point when sand was in filter and Gh 143ppm. The fall is slight and gradual and still within OK limits I thought for the guppies and Platys.

The fish I euthanised was very unhappy looking and had not been feeding for about a week others were beginning to bully it and it swam backwards a lot but no I did not see any red threads though it had some very white poo (guess it must have been eating something)

No further problems this morning but concerned as going on holiday at end of week for a fortnight leaving my son with responsibility of fish 

Thanks Sue had come to same thought. Son has his own tank though he started at same time as me so blind leading the blind lol
