I bought one couple weeks back, 135 shipped . Took one week from hong kong. The instructions took a few time to understand as it was from hk obviously. But pretty simple once you understand it. One thing was you need to remove the pump rubber tube and kind of massage it back to its original shape as it was flatten by the rollers due to sitting for a while?
Currently dosing 57g quite a few mini sps colonies and couple clams. Was struggling to get dkh over 7 with water change and kalk. So far rock steady at 9dkh and 460 ca.
