ATB seems to be a busy bee lately, with their release of their econo line they are also hard at work on another line. The line which is a hang on back skimmer design is still being tested to achieve peak performance with different venturis. This model should be ready to start shipping later this month if all goes well. The included pump is an eheim 1250 doing 300-300 L/hr of air as ATB is still testing other pumps as well. A retail price remains to be seen.
