Which SRO for a 100gal

[rovster]

Just ordered a custom tank and I'm assembling the pieces. I've settled on a 100 gal rimless, and will be running about 20-25 gal usable in a sump. I want to get an SRO, but cant decide on the 1000 or 2000 model. I want to keep a mixed reef, but there will be a good portion of SPS. Part of me is leaning towards the 2000, but part of me says its overkill. This will be my final tank, so an upgrade will not happen uless I move, which is highly unlikely. I want to order it in the next couple of weeks so I can start building my sump. Thanks!

I would say the 1000, unless you plan to add a bunch of fish also. I have the 2000 on a 110g, with the same sump, and it at times is overkill, not keeping a good head sometimes do to the bioload is not enough. This is with lots of lps and 8 fish.

I have a 1000 on an 80g with a tad smaller sump, and it acts the same way, same bioload but with softies.

I will be migrating the 110g to a 150g, and the 80g to the 110g, and the skimmers will move accordingly. I won't think twice about it. Seeing those pumps in action, the scrubbing action within the body chamber will tell you why.

HERE is a post from tech suppport rep, Jeremy, here on their forum where I asked yesterday about their ratings for their skimmers. It confirms what I am seeing and my decision. As the 1000 is rated at 125g, and per Jeremy's post, their ratings for the SRO line of skimmers are for medium to heavy bioload.

I will probably keep a medium bioload, but that can change over time. I feel my tank falls somewhere in that grey area where I could probably get either and be fine. The only reason I'm considering the 2000 is that I want to have a good amount of SPS, and that's what I assumed would be indicated. Cost is not an issue, I just want the right one for the application. Thanks for your input Wildman!

I would still say the 1000, but that is MHO. If Jeremy says their SRO skimmers are rated for med - heavy bioload, then I would not hesitate to get the 1000 for your setup. If not, you still won't go wrong with the 2000. Just remember, if your bioload is not enough for it, it will have longer periods of inactivity.

Get the 2000, even if it's an overkill you can run it at night and have it off during the daytime for peace and quiet.

I am glad you posted that, as I have mine on timers, running from 6 am to 11 pm. Here is a pic I just took of my SRO 2000 under my 110g showing it connected to my waste collector and mechanical timer. Notice where the head of foam is at. It will stay there the majority of the time. The tank pic is a little dated, as I have added a few more corals and fish.
