Steve, I assume that your only posting this spec sheet was a nice way of only indirectly pointing out that I'm wrong. Thanks. That was kind of you.
But I NEVER want to be responsible for passing along bad info. So to ANYONE reading my posts, if I'm wrong, and you think you know it. PLEASE say so directly. I'm posting to disseminate good information, nothing else.
However, I don't think I'm wrong. Here's why...
Your chart shows a spec sheet from some "Bayside Aquarium Supply". I've got that same sheet. It came with my Poseidon, but was only a poor quality (really poor) photocopy. The key to which pump is with in the graph is not legible. But I can see it in your link. The high pressure pumps appear to be the PS2 and PS3. But I don't think that's right. I think the PS1 and PS3 are pressure rated, and that Bayside got it wrong.
I don't know who "Bayside" is, but it's looking like they are rebranding the Velocity pumps as Poseidon. That, of course implies that my T1 and PS1 contribute the same amount of heat, but that's a different discussion. I say rebranding because they did such a poor job on the "instructions" they sent with my PS1, and because I got a nearly identical set of instructions with my Velocity T1. But they are not photocopied, and they have all the exact same information EXCEPT they do not have that graph. And that graph conflicts with all other available info that I can find...
Look at this
Marine Depot link. If you check into the detail pages for the Poseidon pumps, you will see that the PS1 and PS3 are clearly the high pressure pumps.
And look at this
Champion Lighting link. In the detail you will find that the T1 and T3 (apparent PS1 and PS3 equivalents) are also the high pressure pumps, and that they are the only Velocitys that are listed as "pressure rated".
Bottom line - I think Bayside messed up on their graph. And I'm more comfortable making that allegation because of the very clearly sloppy way that provided my instructions. Velocity, on the other hand, seems a bit more buttoned-down. If you can find any info to contradict this, please share it. Thanks.
