Having 9 fish in a 240 gallon system doesn't sound like much. I suppose it also depends on the size of the fish and feeding.

 

Edited...3 Cardinals. I am trying to figure out Skimmer options.

 

easily group that as low... especially for that size tank and with that much biological filtration.

Big players in bioload are tangs and angels. Given that you have enough flow in there most wrasses barely effect the bioload haha

edit: and cardinals have like barely any bioload at all

 

Would a 2400 GPH Return, 2 MP40s and 2 MP10s be classified as "enough?" ;D I understand that the wrasses are "small" fish when you compare them to Tangs/Angels...

I am eying the SWC 180 Cone. 250 "Low" is its rating.

 

thats pretty decent flow as long as you dont have dead spots. And for that tank im sure a SWC would work... but it would have to work hard.

My experiences with skimmers tell me to always go as big as possible! Your best option imo would be to look into an ETSS (aka AE tech) skimmer. If you get one like the AE Tech ETSS 600 XR then you can just put a T and a ball valve in your current plumbing and use your return pump to power it. They are downdraft skimmers so they are verrry effective.
ETSS makes in sump skimmers also but the external ones are better. If you are stuck with in sump then I would say go with as big as you can get... but dont sacrifice quality brand names for size! lol

 

I would check the wrasse compatibility but it sounds ok.

 

Wrasse compatibility will be fine

Although, I would add the mystery last, as it is a Pseudocheilinus after all.

 

I would not go by "low" load. First off... I would like someone to tell me what "low" is. High load is what most people go by. It is as many fish as you can put in your tank which is limited by oxygen. That is where most folks wind up. So your fish list is about what I had in my 90g. So what is low.... that many fish in 200g... 300g... 400g???

Get a skimmer rated for your tank high load. I like getting a skimmer in the 125-150% tank range. So if you KNOW you will always have a small fish load, then getting a skimmer rated for your tank(100%) will still be enough. But if you add more you will need more. If you get what your tank can support...then you will need another skimmer. The 180 cone rated for a 150g heavy is about right with a 2500 and it is not enough for your tank.

 

go buy some fish
