The pictures above were provided by Jesse and Joe of FishLife Aquariums. This is an E24 that was installed on one of their customer's tanks. The picture on the left is the day of install, May 2nd. The right picture depicts the Chaeto growth after only 5 days! (May 7th). Starting PO4 reading using a Hanna meter was 0.13 ppm on day 1, by day 5 it was 0.04 ppm.
Thank you FishLife for the documentation of this install.
Please contact Joe at Fishlife Aquariums or Pop Corals for prices.
