sphack's 40g frag/grow tank

After many years of keeping planted tanks, the time has come to venture into our first reef tank. Much like skipping the community fresh water tanks and jumping straight into the high-light planted tanks, I'm looking at jumping into mixed reef with an emphasis on SPS. For the past few months, I have been investigating/planning a new SPS reef display tank in between our family room and dining room. Initial plans involved utilizing some bow front glass to make a double-bow tank. After more investigation, we decided to do a slightly larger remodel and will be ordering a larger custom 6'x3'x3' setup. Anyway, that is another story (thread) that I'm not quite ready to start"¦

Since the main tank is looking to be 12+ months out, I'm investigating splitting the task into two phases. The first phase would be an initial 40g tank that could transition to a frag grow-out tank. This would allow me to get a system up and running, build a sump and start the fish room build out. Phase2 would be the full DT. The goals of this initial phase is to start small, to collect and start growing corals, and allow the incremental purchase of the infrastructure and hardware.

In the full build-out, I am planning on a 40g breeder frag tank. To enable running this guy early, I'm looking at building a 40g breed sump tank as well. I have seen builds with 20L sumps, but would like to increase the water volume and I have the space. For my big DT, I have a bigger dream sump in mind for later down the road, but I think this should be sufficient initially for the frag tank and possibly for the beginnings of the DT. Not to mention I want to play with a smaller sump before deciding what I want in a bigger one.

Below is an initial flushing out of a "œfrag tank" style system - bare bottom (other than small beds for tridacna clams) and MarinePure ceramic media for bio filtration. I have not ruled out a more traditional live rock setup, but was thinking of waiting until the main tank to go that route.

So, here are my thoughts, plans, ideas"¦ Please review, question, suggest, tear apart, improve, etc. Feedback is welcome.

Tank
- 40 gallon breeder
- 24" AcroOptics LED light
- Coast to coast (or 16" synergy reef) overflow with bean-animal drains
- 2x 3/4" return lines (possibly siphon break from CustomAquariums.com)
- MP40 (or possibly some MP10 or Maxspect Gyres)
- Shelving/egg crate/etc
- Plugs and Walt Smith rock rubble for attaching frags

Sump Design
- 3x 4" filter socks
- 8x8x4 MarinePure ceramic media
- Protein reactor: Currently looking at trying the new Pro-tienClean reactor (B model with 7-10" water).
- Return Pump: Vectra M1
- Refugium area: 7 gallons (9.5 x 16 x 14" high)

Tank / Sump Questions

- The MP40 would provide additional flow over an MP10 and also movable to the main display tank. The MP10 would be limited to frag/refugium only due to glass thickness. Recommendations MP40 vs MP10 vs some other solution

- How much MarinePure would be required/recommend for biological filtration when used without liverock? From the website, it sounds like a single 8x8x4 block is sufficient for 60+ gallon system for active filtration (ammonia, nitrite). The surface area per volume of media is very appealing, not to mention the lack of rock curing required.

- Livestock "“ I'm thinking some CUC snails/crabs/shrimp. Any recommendations in this area? The LFS around here have tangs and filefish in their sump tanks.

- Sand "“ I was thinking bare bottom, but don't know the pros/cons here "“ it looks like the hobby has mostly moved away from BB tanks"¦

- Refugium "“ I have managed to hit the 10% system volume. Any ideas on whether this would be sufficient for nutrient export?
- How fast to corals grow in a frag tank? Would growing out corals in this environment for 12-18 months while waiting for the main DT work?




Here are a number of items I might address prior to setting up a main DT, depending on time, budget, etc...

Phase 1.5 "“ expanding the frag environment prior to DT going live"¦

- Nitrate/Phosphate management "“ once things get up and running, I'm looking at adding either an algae scrubber or reactor.

- Dosing "“ eventually I would like the main DT to use a calcium reactor. From my planted tank, I already run CO2, so adding a calcium reactor would not be too big of an investment. For the frag only setup, I was thinking two part dosing from BRS looks to be pretty straight forward and sufficient while starting to grow out.

- Automation "“ The DT will have a full APEX setup. Whether I pull this into the frag-only setup or not, we will see.

I have liked SkullV's 40g breeder tank and am considering going that route over frag tank... For the DT, I'm considering TBS for live rock, so one concern I have is matching/mixing live rock.
 
I've picked up two 40g tanks at Petco on sale before they ran out. Existing shelving from Lowe's will house the tanks (which matches my other fresh water tanks in the basement/fish room. I've come across a deal on an external skimmer that I'm going to be using. It should be able to support the ful DT until it gets heavily loaded.

Talking over with the wife, she suggested going for a full Liverock display as a chance to try out "the package" from Tampa bay Saltwater's (TBS).

So given the external skimmer and Liverock changes, I'm redesigning the sump a little.

Looks good. Are you planning on branching off your return pump to feed the refugium?

Yes, I'm looking at having a small manifold off the return pump to feed the refugium and any other reactors.
 
Well, I had a big update, but somehow, the browser went back a handful of pages (or closed my tab). Anyway, update lost and now being rewritten.

With the tanks in hand, I'm starting to flush out more of the tank plumbing. Having settled on an extenral protein skimmer, this gives me more room in the sump/refugium. The fuge area is looking to be 20+ gallons and I'm looking at different things to grow in there. My planted tank background is starting to poke out. Anyway, I'm looking at growing chaeto among other macro algae. Mangroves are one possibilities, though I need to see how much attention they require and their height possibilities.

Anyway, here is what the equipment is shaping up to include:
Tank:
* Tampa Bay Saltwater liverock, sand and cleanup crew.
* MP40 for flow
* 16" Synergy Reef overflow

Sump:
* External protein skimmer driven by a Vectra M1
* Return pump, another M1
* Theilen Automatic Rollermat filter
* some form of grow light (possibly BML Grow-Max)
 
Placed my first order tonight with BRS to get my 16" synergy reef overflow and many plumbing parts. It is sad when a valve cost more than the tank they're going on. Petco has it right, give away the tank and the money keeps on flowing.

Next up, pumps.
 
Placing orders, waiting on shipping.

LifeReef VS36 skimmer with Blueline 40HDX external skimmer
Return Pump: Vectra M1
Apex with Lab Probe
Single MP40
BRS Ro/Di water saver plus unit

I decided to stick with the Blueline initially for the skimmer since a) I don't need to change the flow rate in this environment, and b) I want to be able to compare it side by side with the M1. If I end up choosing to pick up another M1 to run the skimmer (i.e., if it is significantly quieter), then the 40HDX becomes a nice backup pump to have on hand, or maybe the salt water mixing pump.


Items being investigate / researched:
* Calcium reactor. In contention: DaStaCo, LifeReef, and MRC so far
* Water tank, salt mixing.
- Need to decide on a pump and plumbing to transfer water into mixing tank, circulate to mix salt, and transfer to auto top off and water change system

Things remaining to research:
* Which salt to use - I would like a salt that can remain in a holding tank for multiple weeks. More reading necessary.
* Water change system / top off - I've heard a lot of good things about the Genesis systems so I'm going to start there
* Fish room layout.

The list goes on and on and on. While orders have been placed, nothing is has arrived yet. I can't wait to start putting together the plumbing for the tank (and seeing how much more material I need to buy before gluing).
