Test Your Seal

Once you’ve connected your pipes, fill your aquarium with a small amount of water and check for leaks. Fix any issues before filling your aquarium completely – you don’t want a watery mess on your hands when it’s too late!

Ensure Compatibility

Flexible PVC and rigid PVC may have different ratings and compatibilities. Double-check that the pipes, fittings, and adapters are all compatible with each other and suitable for use in an aquarium.
