Beckett vs. Needlewheel skimmers

Okay, first of all, we need to set things straight. Skimmers DO NOT directly remove nitrates and phosphates, so to argue that skimmers are proven good because they remove these compounds isnt a valid argument... its wrong.

Hahn, thats an issue of semantics. There are nitrates and phosphates in my skimmer cup. Therefore my skimmer is removing nitrates and phosphates. Period. It doesnt matter how its removing them, it is removing them.

Its like arguing that the accelerator doesnt make a car go faster; It pulls a cord that opens a throttlebody that introduces more air into the engine, and the ECU compensates by telling the injectors to inject more fuel. Its an issue of semantics.

. Im not saying that they dont remove things that might be related to phosphate and nitrate production, but that skimming isnt needed to deal with these chemicals.

No Hahn, thats exactly what you were saying. You're trying to twist the argument into something different because you're losing.

That may be why recircs usually perform better - because they are almost always supplied with the right pump for the body size. I've owned every type of skimmer that's out there as far as I know. They can all work very well if set up properly.

Sherm, the problem is, with todays pumps, its impossible to get the air your typical skimmer needs, and a low enough flow rate to get good contact time. You just can't do it without a recirculating skimmer.


Recircs have bigger pumps because putting a bigger pump on them doesnt destroy the contact time. You can't do that with a non-recirc. I ran my NW200 for a couple of weeks pulling 35scfh and probably moving 600gph through the skimmer. I got very little skimmate. I now pull 30 scfh, and move 100-200gph through the skimmer, and get significantly more. There just wasnt enough contact time before.

I agree with you to a point. I don't think it's impossible to do though. Difficult yes.
