Such Thing As Running To Big Of A Skimmer?
 

So im sitting here in my res room bored outta my mind, so im planning all the equpiment ill need when I get home to start workin on starting my 8' 180g build
Right now im looking into what type of skimmer would be good enough to handle the huge bio-load of a tank stocked with almost 2 dozen large angelfish species and have came to the conclusion that my reef octopus xp-2000 cone wont cut the mustard as its only rated up to 180g. I also wanna get a skimmer that can handle a bigger tank when it comes time to go bigger.
I am kinda stuck on the Reef Octopus skimmers cuz I love there bubble blaster pump and gate valve adjustment. I am also considering the vertex alpha cone cuz of its ability to completely tear it down for cleaning but its also double the price...
I am considering the Reef Octopus SRO 5000 and XP-5000 which are both rated for up to 400g, and the Vertex Alpa Cone 250 which is rated for up to 350g.
But my question is am I going to have below average performace using such a large skimmer rated for more then double the system volume I plan to run? Or would it be a good idea to go that big?

I've got the sro 5000 int running on my 180 plus 80 gl sump. I had started the same type of thread when I was looking for suggestions but not sure how to post the link here. There were great suggestions and feedback if you search for the thread. My tank has been set up since March this year so I don't have a huge bioload yet, but didn't want to be restricted down the road. I don't get consistent foaming, seems to build up then spill into cup but I do get over half a cup every week.

I would have preferred the 3000, but it wasn't available at the time. The biggest issue I have is the clearance between my sump and stand and the diameter of the body, I will have to drain my sump completely and push the sump out if the stand to get the skimmer out for any cleaning or maintenance.

Otherwise, I love this skimmer!!

Size wont be a issue as the stand will have 30" inside so ill have lotsa room for a big skimmer and the sump will be custom made around the skimmer, im more wondering about performance...
This is what my XP-2000 pulls in a week or 2

This is the one I was referring to.

on my 90 i run a skimmer rated for 200g and one rated for 450g so id have to say prob no:)

Yes too big can lead to over skimming which can be bad depending on livestock, running a BK-SM-250 on a lightly stocked 100 gallon caused me issues relating to LPS corals. However running it on a timer to cut down it's duty cycle seemed to fix the problem.

It will be a heavly stock angel tank so no corals, just 2 dozen large angelfish

Any inverts? Over-skimming tends to remove a lot of iodine which can effect them. If it's just fish, definitely no issue I'm aware of.

I dont plan on having any inverts at this point in time, infact the plan was to keep the tank near osmotic.
But we all know how things change LOL
