Is the Water Director included?
Yes. It needed for proper operation and we would never think of charging extra for something so necessary.
Do you sell spare or replacement Water Directors?
Yes. They are sold HERE
Water is overflowing the Media Basket
Tie larger more dense media bags such as Chemi Pure to the middle shelf to pick them off too many holes. Flow is being blocked
Change Filter Floss as needed, make sure to feed livestock with the filtration pump OFF
How high should I have the water level?
Disregard the MIN/MAX line of the aquarium. You need a higher water level in the rear chambers for proper filtration and water volume. Please add new water to the 2nd or 3rd chamber while the filtration pump is ON so the level comes up to around the first, top shelf of the Media Basket. Most set it just under the Filter Floss to avoid a waterfall noise.
Do I need to remove everything from chamber two?
Yes. Remove the stock low quality filtration parts
The water director is not "directing" 100% of the water into the basket.
This would only be possible if the direction piece was permanently sealed into your aquarium. The water director transfers as much water as possible while still being removable for maintenance. A small amount of bypass is normal and does not affect your newly upgraded filtration. Water is circulating through the entire aquarium multiple times per hour and through the entire Media Basket. The Water Director was completely redesigned and updated around April 2019. It will capture more water and only one director is now needed no matter if you modify the chamber.
Should I keep the sponge in?
YES and No. If you are not running any macro algae then no, take it out. Sponges can lead to nitrates in a saltwater reef setup. If you are using macro algae then keep the sponge before the return pump to protect it from any loose macro algae. Keep it clean to avoid the risk of nitrates. Keep a spare, swap them out during water changes so you are replacing with a sponge that is clean, and dried out killing all harmful detritus.
