Questions and Answers:

1. UV light/glass cover broken/doesn't work : if damaged, send us an email and some pictures about it, we will resend you a replacement. If not, rotate the top lid 180 degree, and try it again. Because there is only an inductive part on one side

2. Missing pieces: We may miss some pieces when packing, please send us an email

3. Leaking: Please check if the glass cover was broken. If not, make sure all pieces are assembled correct, adjust the o-seal ring on the top lid and put the filter lower than your tank, and make sure water can get through the green hoses soomthly

4. Loud noise from the motor: You may need to check the impeller on the top lid if there is anything in it, and clean it.Then try it again

5. Not pump water: Press the blue button on the top lid to compel the extra air out of the canister and try it again

6. The flow is slow: Add enough water into the tank, and adjust the cotton and medias

7. Note: Push the glass tube all the way down, then twist it to lock in place

Exactly what i wanted

Exactly what i wanted
This bad boy is awesome. I wanted a simple filter for my newer big tank and this guy works great. high quality materials and a big magnet on the pump. comes with plenty of tubing amd everything you need to customize it to your tank. MOST IMPORTANTLY: its SUPER easy to clean. the in/out tubes are mounted to a block that has a strong latch. You open the latch, which simultaneously unhooks the two pipes, and also CLOSES A VALVE in the block, stopping water from siphoning out of your tank. this makes it a breeze to unhook it, carry it to the sink and clear out the filter trays. it also means its easy to use the pump as a drain for your tank during water changes. i cant speak to the efficacy of the UV light, but it does shine brightly, and ive had no leaks or issues otherwise. my one complaint is that it was almost silent for the first month, but after one of my clean outs, it developed a very slight rattle. its barely noticeable unless im sitting quietly in my living room.
