Dear sharonf
Koi goldfish and comets will bread with eachother and produce a mixed offspring that you won't even be able to give away.(no offence intended)
Depending on the fileration you use on a 31000 litre pond and if you have a gravity feed or pump fed system what kind of filter media you use and your waters ph at source. Not to mention average depth to water surface area you have. But lets say your pond is unfiltered then maybe about 8 to 10 fish if you wish them to grow fully and not feed them ever.
If on the other hand you have a Mature mega filter with bottom drains and all the whistles and bells attached and water changes being done on a dayly basis then maybe 100 depending on size.
As for salt content now that is up for debate. Personaly i don't use any. But other people do, but don't go above 0.3%. And it is all relative to the PH and KH.
Wich brings us nicely on to baking soda people use it to regulate ph as they do with crushed shells in the filter system.
Your red sopts on your fish could be due to ammonia poisoning as your filters are not mature yet you will have a spike in the ammonia then a gradual rise in nitrites this will last longer than the ammonia spike but regular water changes should keep it in order. A low PH and KH will make an ammonia spike harder for your fish to handle.
So a good idea would be to get a test kit for your water peramitors, something that covers ammonia nitrites nitrates PH KH and GH, salt levels and desolved oxygen if you are using salt.
Hope this helps
