AllPondSolutions 水族箱內部過濾器 1200L/h 1200IF

My old internal filter was barely moving water in the corners, but this one creates a visible current that reaches the far end of my 200-litre tank, and the oxygen output seems way better for my gouramis. The pump is quiet enough that I can't hear it over the air stones.

Water clarity improved noticeably within hours of installing this filter, and the dual aeration really keeps my cichlids active. It's quiet enough that I forgot it was running, and the 1200L/H flow handles my 100-liter tank with ease.

The flow rate is definitely a step up from my last filter—my tank's surface stays noticeably cleaner, and the fish seem more active. Took a little fiddling to get the outlet angled right, but once it's set it does the job without fuss.
