Hello there And welcome. I wouldn't worry to much about the water hardness but you could find out what it was were you bought the fish from and see if there is much difference, your ph is fine they like a ph between 6.8-7.5 the main things to concentrate on are Ammonia, nitrite and nitrate and you say they are fine, what are your readings ?

I have the same situation here. Generally, my water is very hard like yours. I worried about it as well to start with but there are more serious problems than that... If you buy your fish from your area, they will be most probably 'used to' the water, so it should not cause big problems. It is very difficult to decrease GH (filter on your tap, rain water, importing water from a soft water area?). My fish has been swimmimng in my hard water for a month and seems very happy and active. I also noticed that GH went down a bit after about 20 days and is lower than the hardness of my tap water. Wonder why? Possibly due to some acids from the waste?(You can test your tap water to check if it is already hard, which is probably the case.) Have you got any rocks in your tank? These can contribute to high GH readings because some of them release calcium. Your ph seems great for most goldfish. Mine is about 8 or above and I was told that it is still fine as they again 'are used to it'provided that they come from a similar environment. Any sudden changes in ph may be dangerous and fish don't like it. If you want more info on goldfish try thegoldfishbowl.co.uk They have the Atlas of Fish where you can find info on fish profiles and the requirements. Stay reassured you are not the only novice! May I ask what happened with your comet?
Readings for nitrite should be 0 and nitrate under 50 better below 25 so if yours is only 10 then thats perfectly fine, once the nitrite is 0 then you can rest assured that you have no ammonia left, your fish sounds happy enough so just keep up with regular part water changes and testing and you should be fine or rather your fish will
Goldfish always appear hungry so don't be fooled just feed about twice a day or once a day untill your nitrite readings are 0, floating pellets are ok but you have to be careful with fancy fish as if they take in too much air they can get swimbladder trouble, you could try soaking the pellets in some of the tank water first and then feed them to your fantail just to be on the safe side.
