If anything, 25% weekly would be too little. Goldfish have a massive bioload and you're overstocked with 23 of them if they are all to remain in there.SaveThemAll1 said:Hi ,So theres a 400 L tank with 23 goldfish:3 are about 25 cm, 4 are about 15 cm and the rest are less then 10 cm. I want to hear your opinions on the WC scheduale reccomended, is 25% once a week is too much? please share your opinions, thank you!
