Our in-depth look
Who it's for
Tanks with sponge filters, warm tanks, and heavily stocked aquariums.
Who should skip it
Bettas don't need strong aeration; keep surface movement gentle.
Tips
Place the pump above the water line or fit a check valve so water can't siphon back into it if the power fails.
