Planning tank..(Opinions needed)

Im contemplating setting up a 150 now that I have the room for it.My plan would be to house an officianalis or if not available a larger octopus such as Vulgaris.

I have a friend that is selling a large cpr sump/skimmer. Im not sure how effective it will be nor have I ever used a wet dry system before.

He is selling it for so cheap that its tempting.

http://www.aquacave.com/detail.aspx?ID=1416 is a description of it. Any opinions?

Typically I have just used a sump, big skimmer and fuge and have always had great success with this. Im unsure if I trust the skimmers available with this filter. Also, do you feel that the wet/dry portion is necessary?

Or should I just invest in a large skimmer and throw it in a 55 gallon sump?

I am not a fan of sumps with built in skimmers. Usually for the same money or less, you can get a much more powerful skimmer in its own sump. It is also very easy to add a 'wet/dry' portion to any sump - you can even use the skimmer effluent to feed it. I think I would recommend off the shelf units like that if you need it to fit the space, otherwise, I would go with a bigger skimmer. :biggrin2:

I don't know if you 'need' a wet dry...they are easy to add, just keep up on the nitrate testing.

Side note: I have a cubic foot of bio bale and am thinking of adding it to my ceph system just 'cause.

Thanks for the comments..I general have the same lines of thinking. Im just distracted by the small price tag my friend is offering it for. =)

Ive decided to go with AquaEuro Recirculating 265 skimmer

With the focus of trying to keep water temperature as low as possible, I will be running everything external.

My idea right now is to have the overflow from the 150 feed to a T that will go directly into the skimmer and also into a sump that I will house either or both macro-algae and bio bale. An external pump will then pump the water back into the tank..

Pretty simple and straight forward.

Once I get closer to putting it together, Ill draw a diagram.

Any foreseen problems or comments?

Paradox,

Are you indicating that you will run the skimmer from just the overflow with no pump? If so could you explain more about how this type skimmer works since we are also planning a new tank, I am always up for new ideas :cool2:

A drain from the overflow feeds directly into the skimmer body. Most often, you still need a pump to inject air bubbles into the skimmer but both the intake and output of that pump are through the skimmer body. A 'recirculating skimmer', or a 'recirculating mod'. Sometimes this kind of set up is run with two pumps - one for recirculation and bubbles, the other to push water into the skimmer body.

As thales explained, this is called a recirculation mod. It has been found to increase the efficiency of your skimmer for a few reasons.

-It will skim the water that immedietly enters the overflow
-It will produce finer bubbles
-The water will stay in the chamber longer allowing for more efficient skimming.

The original pump is modified to have its intake and output BOTH come from within the skimmer body, so all the pump does is recirculate water in the chamber increasing its time spent there as well as create finer bubbles.

The overflow will be plumbed straight into T where one end enters the skimmer and the other to a gate valve emptying into the sump. Depending on the amount of water flowing from the overflow and the capacity of your skimmer, you adjust this gate valve to controlthe amount of water that enters your skimmer.

Look up recirculation skimmers or mods on reef central and you will have hours of reading. I spent about an hour and 30 dollars doing this mod on my current ASM skimmer and I will never have a skimmer without this again.

Does anyone have any suggestions on a good 'not so expensive' return pump that I can run external.

My concerns are

-Heat
-noise
-1000-1200 GPH (Approx 7-8x tank volume/ hour)

Paradox/Thales,

Thanks for mentioning and explaining the in-line skimmer - definitely on the design board for the new tank. I envision using the sump end of the tee for water changes :wink:

Paradox,
Please post any positive results you have with the pump search that meet your critera. We have looked at pond, pool and sump pumps but they have failed at least one of the first three (#1 being the cost) requirements.

dwhatley-
Ive decided on a PanWorld 50PX-X. I got it used from a member on RC for 100 shipped. My research shows them to be very quiet and the stats meet my requirements. Also I found this thread http://reefcentral.com/forums/showthread.php?s=&threadid=828812&perpage=25&pagenumber=2 that shows how to make it quieter and drop the temp in the tank another degress or two.

I havent hooked anything up yet for Ive been busy making the stand.

My list of things to do:

-Drill the back of the tank for overflow (I think the bottom of the tank is tempered, so Drilling the bottom will not work)
-Get acrylic to make 2 overflows. (One in each rear corner)
-Make sump/refugium
-Add all the plumbing
-Research and make some custom agrocrete rocks
-Find a hundred homes for officianlais eggs.. =(

I was trying to do this as cheap as possible as well, but this project just gets bigger and bigger. The DIY aspect is still saving me tons of money, but things to not be thrifty about is probably the skimmer and return pump.

My costs so far:
Aquaeuro Recirculating 265 skimmer -280
stand - 102 - trim
90 - wood, panels, and hardware
150 gallon glass Tank - 200
Panworld Pump - 100

Wishlist:
WavySea ocean simulator or the cheaper sea swirl.

Concerns:
I am concerned about flow. So far, I will have two overflows and a return pump that will probably return at about 900-1000 gph. The return will goto a Wavy sea wave maker and placed on the top center of the back of the tank. It will be set to point diagonally down and rotate 180 degrees covering the tank from left to right. I am unsure if this will be enough flow to not have too many dead spots for excess detritus build up.

A cheap way to add flow, but may add too much temperature to the tank is a maxijet that has been modded. http://www.mjmods.com/

I will also need to decide if I want a shallow sand bed or go barebottom. This will probably be decided upon if I am able to get officianalis or not.

Ill post some pics and update when I achieve more progress on the tank. If anyone has any comments, they would be greatly welcomed. This is my first custom design of this size, so a lot of this is new territory for me.
