My 240g FOWLR

RayL
The blueface, french, and emperor have pretty much gotten to adult size. The Scribbled, personifer and Queen are 5-6" range. I've had these all since they were juvie except for the blueface. Amazingly they get along well. though the emp tends to show its dominance once in a while. If i cant upgrade this year then im thinking of selling the three larger angels and adding some butterflys.

Thats a good plan, I love angels as well and as soon as I can afford my upgrade I will be making an angel and tang tank
 
I think I'm going to have to catch the semilarvatus this weekend and give him a time out in the fuge. He's just so aggressive to the falcula and the parachaetodons...

From the video he looks huge! Your dusky has also grown significantly, is he aggressive at all? Mine seems to be getting more aggressive as he grows.
 
I'm not a fan of high flow returns/sumps. I don't see the point to it. I use a submersible... I'll have to check the model number, I think it's a QuietOne 6000?

Completely agree!!....

Unless you have a beckett skimmer I would run about 20x the amount of actual water volume in your sump for your return flow. This will make your filtration more effective and rely on CL/circulation pumps for your water movement within the tank

Not disagreeing, but I wondered it you could explain your logic.

Why do you like 20x the sump volume? How does it make the filtration more efficient.

Again, not agreeing or disagreeing, just want your point of view as I'm getting ready to purchase a return pump for my new 240 fowlr.
 
its the ability of your skimmer to process water, if the flow is too fast the water will just flow by the skimmer instead of being drawn into. A beckett skimmer will process a lot more water than a needlewheel. If the speed is too fast for your skimmer the water will still get processed just at a slower rate. This has been a heated debate before....Flow through the sump, Which is better

IME if you have too much flow you will turbulence in the sump and any micro bubbles that do get produced will make it back to the DT
 
Makes sense...

Could you not do what many people do with a fuge and restrict the flow to the skimming chamber?

My concern with lower return rates has to do with the nitrification process and ensuring adequate flow to the denitrifiers, which I assume are inhabiting the live rock in the absence of bioballs.

Although from the looks of Peters tank, maybe I should just do what he does.

I'll stop hijacking and leave my equipment questions for another thread.

Thanks for your reply azjohnny.
 
Nothing wrong with equipment questions here :) Basically IMO as much of your water as possible that comes down the overflow should be going into your protein skimmer.
 
I feel with keeping a marine tank its all about nutrient import and export, if you can export organics before they become ammonia you will keep you nitrates at a very low level.

I have set up my FOWLR water flow wise a lot like a reef tank with over 40x water turnover within the DT using Ecotech pumps. This gets the organics removed via the overflow, into a felt sock and the remaining getting skimmed out. I have removed about 90% of my sand and that has been a big help, I am about to go BB

I suppose that's based on the pump for the skimmer. So if your return pump is double the flow of the skimmer pump, half the water coming to the sump would go unprocessed, so to speak.

This makes sense.

This has been helpful.

Sorry, I missed this post :eek: I have to admit looking at the fish lately, several of the butterflies are quite large at this point, especially the saddleback and marginalis!

The dusky has definitely grown a bit, especially in girth. Fatty! :)

BTW, I put the trap in Friday night, opened the door, and the golden butterfly swam right in to check things out :lol: Didn't even get the food in there yet!
 
Well, there's the physical aspect. Unless you have a sump specifically designed for high flow (which I've seen done... pretty neat) you end up with splashing/noise, salt creep, microbubbles etc.

The other main thing would be, IMO, if you are going through all this trouble to surface skim the DT, I'd like to capture as much of that surface water in the skimmer, rather than it just shooting past the skimmer to be re-diluted and pumped back into the tank.

That is great that you got him out without a fuss.
Are you going to store him in your qt tank?

Be prepared for all the commentary on how you need to add sand becuase it looks better :rolleyes: :debi:

+1 on this, people are constantly asking why I have no sand or telling me I need sand :deadhorse1:

No, I have a large fuge I'll drop him into. Though to be honest he's been in the trap this whole time and is doing fine... eats well too. Maybe keeping them in sight of each other is a better plan?

Yeah, the sand thing really gets to me, but I succumbed,. and added it :eek:

Thanks for the info. Could you point me in the direction of some of those high flow designed dumps, I'd like to compare before I settle on a sump design.

Just tell any good sump designer the dimensions and flow you want though it and they will make it for you.
 
My 280 gallon that I'm setting up now will be BB no more sand for me! I set up a 150 gallon about 2 months ago BB and I love it! Keep flow going across the bottom stays pretty clean!
