Upgrade Time!! 40B build

Well, the WAF (wife acceptance factor) of my 20 has reached the point where she wants to not only relocate the reef tank, but make it bigger. (Bigger is better, she says...hahaha)

I've ordered a 40 breeder tank and stand from my LFS for a price I couldn't refuse. I plan on utilizing the HOB skimmer and filter (I run phosguard and RoX carbon in it) from the existing tank. I will need a bigger heater.

A few questions:
1. Will my two Hydor Nano 425s provide enough flow? If not, would the Evolution 600s suffice? I use the Hydor smartwave to alternate the pumps and vary the flow, so they aren't on at the same time.

2. (You knew this was coming...) A sump. I know the more water, the better, but is a sump considered "required" for a 40? If so, would my existing 20 (high, not long) be sufficient? I also have a 10 gallon tank that could be used. I'd probably relocate the skimmer and HOB to the sump if I use one.

3. If I use a sump, is the BeanAnimal overflow overkill? Or would some other method be considered "better" for a 40?

Regarding the transfer from my existing 20 (which has some turf algae on the rock, so I'm going to use fresh dry rock from BRS), here's my plan:

1. Day 0
a. Set up new tank.
2. Day X (when I get the stuff)
a. Install circulation pumps, heater.
b. Add dry rock to tank.
c. Add water.
d. Cure for 6-8 weeks.
3. Day X+56
a. Remove water.
b. Aquascape rock
c. Add sand.
d. Add water.
e. Move clownfish, cleaner shrimp, pistol shrimp and goby to 40G.
f. Clean skimmer and HOB
g. Move skimmer, HOB, ATO to 40G.
h. Move electrical panel to 40G.
4. Day X+57
a. Remove water, rock, and sand from 20G tank.
b. Clean corals.
c. Quarantine corals until 0 PO4 and no algae.
5. Day X+Y (when the corals look algae free)
a. Move corals, snails, hermits.
The reason I'm QT'ing the corals is there is some algae on them, and I don't want it tranferred to the new tank. I already do large weekly PWCs (on the order of 10 gallons), and only feed twice a week, a single mysis to each fish (two clowns and a goby). I'm not sure where the turf algae is coming from, but I'd rather not start with it in the new tank.

Thoughts, suggestions, comments, criticisms?

The 2 nano's will not be nearly enough flow. I would run the 600's but scrap the alternating wavemaker.

Yes, do a sump if possible! 20 gallon preferred over 10, as you can fit much more in it in terms of equipment and water volume.

In terms of overflow, on my 40 gallon, I did the glass holes 700gph overflow. Very simple and doesn't take up much space...

Thanks. I will keep the nanos in the QT tank so I have some flow in there.

WRT the overflow, what kind of failsafes, if any, does the glass-holes overflow have? Also, is it gurgly/noisy?

Quiet as long as the drain is under the surface of the water level in the sump. Really not too many failsafes needed. I used the Eshoppes flex tubing for the drain line and braided tubing for the return to a dual locline nozzle. As long as you leave enough room in the sump in case of a power outage for everything that will drain out, you're all set. You can drill a hole in the return nozzle just under the water surface (what most people will do) or what I did is set up the nozzles so they're just barely under the surface of the water. The water will be drained out of the line well before the rest of the water over the overflow box line has drained...

Thanks for the info. I still think I'm going to go w/ the BeanAnimal, since this thing will be in the family room...I want that peace of mind...

That being said, I might downsize from 1.5" to 1" on the siphons...

Not familiar with that overflow, I just went as simple as possible... But I would imagine 2 1" siphons would be plenty.

Why not add sand and dryrock right away? I don't know why you'd wait 56 days then remove the water and add sand. The sand will help the cycle by being covered in nitrifying bacteria. I'd do sand and dry rock day one. Also, you will go through a diatom bloom so why not get that over right away rather than waiting 2 months, adding sand then going through it...

Just a thought.

So here's my plan, in addition to the timeline above (and moving the add sand to the cure/cycle part)...

The existing 20 will be my sump. Not sure if I'm going to make chambers or not, but I'm guessing at least 2 will be needed. I'm going to modify my existing HOB skimmer for use in the sump by extending the intake and output lines so the water level in the sump doesn't need to be so high.

I'm going to relocate the heater and the HOB filter box into the sump as well. However, I'm considering getting rid of the HOB filter altogether, and placing my carbon/phosguard pouches at the bottom of the overflow lines.

WRT the overflow, I'm not going to do a full C2C for the BeanAnimal. I will use 1.25" lines for all 3 siphons. My only question is what flow rate should my return pump have? I have to take the following into consideration:
- My corals, right now, are primarily LPS (hammer, torch, frogspawn). I have acans, zoas, duncans and birdsnest as well. What flow should these guys have? I don't want them getting torn apart in current. I was going to use 2 of the Hydor Koralia 600 pumps in tandem in the tank. There will be approx 4ft of head on the return line. I was thinking about the Syncra 2.0 (Sicce Syncra Silent 2.0 Pump (568 GPH) - Bulk Reef Supply) Based on the specs (Log In) it looks like the 2.0 can do approx 350gph at 4ft. Is this enough?
