stats are:
Ammonia 1ppm
Nitrate 3ppm
Nitrite 0ppm (lots of plants to mop this up)
Will try the stocking thing.
That's why your fry are dying.
10% every other day is obviously not enough - I believe that other fry raisers on here, even with filters, do 60%+ water changes daily, so maybe you should try a sponge filter and upping your water changes to minimum 50% daily. In the meantime, a near-as-100%-as-you-can-possibly-manage water change will bring that ammonia reading down to 0, which is where it should be anyway, but definitely should be when raising fry
Hope that helps a bit!
thanks, just done a 90% one and ammonia is inbetween 1 and 0 now a bit hard to tell but not as high as it was.
nitrate is 1ppm
nitrite is still 0ppm
