Realistically, it’s probably 10-15 gallons. It’s a 40 gallon tank but I have a hatchling in it, I wanna know if I can use a penn-plax cascade 1000 or if that filter is gonna be too strong. I have no idea about filters, I didn’t even know what a canister filter was until a week ago. I bought this one though and wanna know if I can hook it up or if I should wait and keep the one going that I have inside the tank for now.
