Question:Does this require a specific size tubing? I have standard tubing that I use for all my other equipment but it doesnt fit on this filter.
Answer:  Soak the inserting tip of the tubing in hot water for about 30 seconds before you slip it on. This softens the tubing making it easier to slip over any fitting. I usually warm up some hot water in the microwave oven in a coffee cup and dip the tubing in it. All tubing and fitting sizes vary slightly from manufacture.

Question:How often would one replace the sponge in a 6g shrimp tank? if cleaned regularly.
Answer:  I’ve had it in 10g shrimp tank clean it about every 2 weeks and have never had to replace the sponges the second sponge they send I recommend keeping in your tank for bacteria growth then swap them out and clean off the used one keeping both in your tank but only one connected to the filter.
