I would be more concerned with that tripping a breaker and leaving my tank offline until I can get home.
But anyways, my tickets was answered and should have new motor body on Tuesday. I've taken out the other Gyre to clean the other day (mainly to inspect the cable). I can't say that it looks any different in quality, but it was not cracked, at least not yet. I did get that Gyre later and it came with a new style rubber mount, so maybe it is new cable type as well.
On a side note, cleaning them did help flow quite a lot. Main dirty parts were the grill with coraline and perhaps some sort of fuzz on the propellers or whatever they are called. Neither seemed very out of hand, but I guess even a little is enough to reduce flow by what seems like 20-40%. Had main one up to 80% before, now even at 50% it seems a bit too strong.
Still looking at those WAV powerheads lol. From the looks of them it seems to me that they are some sort of modified version of Sicce XStreams. Very similar design outside of the mount and Neptune logo embedded into the front grill design. In comparison to Sicce ones at $250, WAV are cheaper as well. perhaps simply due to the lack of the controller parts.
