Ok so I just received this Sunsun canister. I have rinsed and filled the baskets and set them back into the can, situating each one so they are flush. I then added the filter sponge son top. I'm wondering if I've done this correctly. The lid was very hard to squish down and get closed. Currently top to bottom I have, 1 blue course sponge 3 white finer sponges Plastic lid Basket containing mesh bagged aragonite and white sponge on bottom Basket containing matrix and white sponge Basket containing included ceramic and white sponge Basket containing included bio balls and white sponge. There were pretty much no instructions on setup so I'm needing to know if this is good or if I need to change something before I fill it up! Thanks Also, do I have to use the entire spray bar or can it be shortened? There are removable pieces.
