Skimmer for 125g fowlr (Reef octopus)

I think you will be fine even with heavy feedings. You can get one rated for 150 gallons for a little safety room. 300 gallons is overkill. If you plan on upgrading then that is a different story, but this is also a FOWLR and not a reef tank.

 

might add corals someday.....

 

so finally should i go for SRO 2000 or NW200?

 

Manufacturer rating is not based on any standardized system. Most all skimmer companies list a range from heavily stocked to lightly stocked. the high (lightly stocked) on that range is really pushing the effectiveness on the skimmer. If I have to rank your skimmers by power, I would rank them like this.
RO-PS-3000INT 8" skimmer w/ 1100 lph of air

Tied for second
NW-200-6540B 8" skimmer w/ 720 lph of air
RO-PS-2000 INT 6" skimmer w/ 960 lph of air (could possibly be a tad better due to the higher air)

I don't know about FO tanks but most I see include a much higher bioload than reefs because of larger feedings.

For reef tanks, I typically recomend 6" skimmers for tanks 50 - 100g, 8" skimmers for 100 - 180g, 10" skimmers for 180 - 300g, and 12" skimmers for 300g - 500g. I am sure many would argue this, but that is the way I do it. My 225g tank has a skimmer that the manufacturer rates up to 800g.

 

You can't argue your success with it.

 

I have a SRO-2000xp-INT on my 125g that is full with 3 tangs 4 decent sized wrasse and a few others it does its job, but I got a SRO-3000sss for my new 125g so I can feed more and keep it SPS dominant.

 

Thanks, this is what i was looking for.... so i guess i go with SRO 2000INT.. can u tell me the sump depth required for it? coz others say 6" but on the site is 8.2".. really confused, coz i only have a 25" gap and skimmer is 22", so i cannot elevate.... also about the noise, coz its gona be my room and gona be open sump....

 

Sorry, I cannot answer that. I can say that I would tend to lean with the manufacturer recommended depth because if there are problems, they by default will point to that as your problem.

 

thats true..... thanx....

 

Whats ur sump water level depth for ur sro 2000?
