No problem, FYI there are stickers on the filter motor. They will come off and get sucked in the side of the motor which will mess up the motor. U should get this one https://www.amazon.com/Intex-Krystal-Cartridge-Filter-110-120V/dp/B005QIYL7E. The flow rate is so high it makes short work of 200 gallons.
I love the overall design of the zen tank but overall I believe the filter is cheap and could of been done better. So I bought this and at 1000 power flow rate itll only need to run for a short time. Plus the unit itself and filters are cheaper.

make sure the diameter of the pump is matches your hoses. I have run it around 6 hours per day or more and change the filter every 1 to 2 weeks
