I checked the box (saved it just in case) and it does indeed say "up to 60 gallons". I don't have a water test kit right now, but I will definitely go and pick one up tomorrow to make sure all is well in that area. They are common goldfish, and they've definitely already grown a lot since the day I got them, so I won't be surprised to see them continue growing in size at this rate. Thanks again for all your advice!
30-50% - I never heard that advice for water change before. All the research I had done said 10-20%, so I went with the midway point there. I always use a water bucket to prepare their water though, and even though the water conditioner says it works I immediately I leave it for at least several hours (usually 12-24) to be sure.
I have one more question, if I may bother you with it - sorry for so many silly questions here. I'm a bit worried about waste getting caught in the tank gravel. I have a siphon vacuum for cleaning, but it was a very cheap one at around $3.50 from the pet shop, and it doesn't really seem to be removing anything from the gravel. Is this more likely because the tank is relatively clean, or is there a higher power siphon that you would recommend that might do a better job with cleaning? Thanks again!
