Hey guys, I have been rather inactive lately which I do apologise for. I have not stopped keeping fish or lost my motivation again I just have been busy. To the problem at hand! My fish have white spot! Now I am treating with the most powerful medication I have which is sterazin. Now I know the drill so here are my tank parameters. Ammonia: 0ppm Nitrite: 0ppm Nitrate: 40ppm Water changes every Friday or Saturday, using Seachem prime. Filtration is estimated at around 180 litres per hour I have two water pump driven filters and a sponge filter. All but the sponge filter are cleaned when doing water changes. Tank size is 60 litres.
