Yes bio balls and sponges should be removed slowly or it can create a problem in your tank.

I've run a 29 gallon reef without a skimmer for close to 2 years. In a tank that small, if properly stocked, water changes are sufficient. The tank only has 2 small fish (fiji damsel and a bi-color pseudochromis) which, I think, helps.
