Water change

[hammadkatiyar]

I have 60 gallons fowlr tank including sump. I do10 percent water change twice a month. This practice is going on for last four years. My nitrate n phosphate levels are almost zero due to media reactor. Even many fishes survived in my tank for at least one year n then died. Its being now 4 years, do i change 100 percent water or keep doing the same practice? Pls advise

Why are you considering a big change?

Because the fish died?

it's going to depend on what you want to accomplish with the water change. I would not change 100% of the water - it would cause an imbalance imo - I would think continuing with small, regular water changes would be the way to go.
