Actually, I am gonna go with a PM hot 1 for two reasons and thought I post here for all of you who may be deciding about this.
First let me say that despite what others may say, the owner of PM is a jerk! sorry but it's true...he wants to sell each and every skimmer himself to get the max profits. Even if you notice the ones you can order from Marine depot and others for example ship directly from the PM factory. The PM owner doesn't know the first thing about marketing or his FINE product woulda taken off much better than it has. I guess he doesn't want to expand and get the manpower to produce a lot more skimmers but that's his decision.... I am still going with his product anyway!
One reason is the PM needs only a 2" clearance above (not behind) the tank whereas the Remora needs at least 4 inches of above tank clearance. I have a canopy that sits pretty close hence the PM choice...
Second reason is that I am worried about the Remora's injection nozzle clogging, I have searched and searched and asked a ton of people about what to do about the injection nozzle clogging...remember I had bought an old Remora and it didn't skim because the injection nozzle was clogged. Unless you have the Remora in your hands and see what I mean, you can't really get what I am saying...there is no way to manually clean it like you can do with PM's venturi. I tried fresh water & vinegar to no avail. The Remora might be fine for months or even a couple of years but once the injection nozzle clogs up, you gotta get rid of it...
Anyway, this might sound...ummm bad but I feel like there are a lot more people out there with Remoras (partly because of better marketing by AquaC's owner) and altho this a fine product at the beginning, once these things clog up, people want to get rid of them and they boast about the quality of them just to dump them. Of course they are heavily backed by those who haven't had it clogged yet and so there are those who genuinely like them, hence you get the very high recommendation rating by many for the Remoras.
So basically my number 2 reason is that I can at least clean the PM venturi manually if it clogs up.
I am not trying to start any heated debate here. I just posted with my "TRUE" feelings about these skimmers, in hopes that it may help someone chosing between the same 2 models.
I am ordering mine tomorrow. I will let you know if I have any issues with that as well.
peace out.
