210g build in TX

I have a thread on my local reef club's website, but my wife has been bugging me to start one on RC, so here it is.

We had a 150g tank before we relocated. It was our first foray into reefkeeping, and we made a lot of rookie mistakes, but it was fun and addictive. We sold the tank to a local buyer and hope that he is still having success with it. Anyways, after buying a house here, I found a smokin' deal on craigslist for a 210g and all the fixin's. That was a year and a half ago... (whoops!)

I hired a local stand builder to pick it up for me and build a custom stand. We had some display cabinets that we wanted it to be similar to, and the builder did a fantastic job in our opinion.

I began researching setups and making plans. I pored over the many LED threads here on RC, and made the decision that I wanted to try LED lighting. I found a new product early in 2010 from a Polish company called PacificSun. I had a bonus check from work burning a hole in my bank account, so I ordered up the 60" Deimos fixture. It's a veritable work of art, with the unfortunate price tag to go along with it.

Due to new product delays, it didn't arrive until after the tank drilling which came next...

As part of my research I decided that I liked the Calfo style overflow instead of the plastic towers that my tank came with. So I carefully removed them. They came out fairly easily.

And then I contacted a local reef business to modify my tank. He drilled the holes that I requested in a couple of hours.

He then started work on a custom acrylic refugium and sump. A few weeks later I had the results sitting in the living room.

A vinyl under-shower liner was procured and installed in the stand base.

And then the tangled web that is my plumbing was begun. I am going with a closed loop recirculation system. I found a Hammerhead on Craigslist. Glad that I rebuilt it, as the seal basically disintegrated when I took it apart. That's topped by an Oceans Motions 4-way. 2 outlets are to manifolds at the bottom of the tank and 2 are at the top. The return pump is a Dart. The overflow is split between the refugium and sump, and is controllable with valving. I had a weir made from custom glass and installed it with what is quite possible the world's worst silicone job.

A word to the wise... if you are going to do this, allow a little extra room in your measurements, and definitely get a second pair of hands to help installing it, as glass binding against glass WILL chip.

Then I started the water testing. There were unfortunately several leaks. My can of PVC cement was running low and got a little thick, but I plodded on instead of getting some new glue, and paid the price. 3 more water tests later to fix additional leaks and poorly-tightened joints, and everything was finally good.

Unfortunately, I got some water under the stand during my several leak tests. Mold was discovered when we moved the stand back to its final resting place. Luckily, it came right out of the carpet, but I'll be keeping a close eye on it for any recurrences.

To be continued...
 
This post also takes place over several months. I hope to not be quite the procrastinator going forward...

My wife and I were trying to decide how to mount the light fixture when we determined that accessing the tank would be an issue with this monster and the hood we have. I had a flash of inspiration and engaged my stand builder to acquire some cabinet drawer slides; he mounted the fixture using them as you can see here. It worked out great, as the light easily slides out of the way providing all necessary access to the tank.

Of course this method only works nicely if you have some space between the wall and tank for a fixture this size to slide into...

I was intrigued by the many foam and rock wall builds, so I decided to try my hand at my own version. I acquired 100 pounds of dry rock from the guy who drilled my tank, bought some eggcrate and got to work. A BFH and chisel made short work of the big pieces, and here is the initial layout.

It turned out fairly nicely, or so I think.

I took the advice of others on RC and bought "pond foam." Unfortunately, the brand that HD had in stock was not UV-safe (a fact I discovered reading the can closely AFTER buying it), so on Saturday I put epoxy and sand on (most of) the exposed foam, and it now looks like this.

While the rock wall was in progress, I mounted my lighting ballast in the stand and found some really cool individually-switched power strips, so I bought and mounted those as well.

Yesterday I finally got my butt in gear and mounted and plumbed my RODI system.

I still have to clean the water barrels and set them up, but I'm almost ready to go.

And as a teaser, Santa bought himself a couple of neat toys courtesy of the encouragement of others here on RC...

I'll be updating this thread when I find the energy and time to work on my tank. Since it's so close, I hope that it will be often, but no guarantees.

Your input and critiques are welcome!

I made a little progress today... I grabbed some parts to give a finished look to the under-sink plumbing for the RODI system

Looks pretty nice I think. Tomorrow is supposed to be a little warmer, so I'll tackle to RODI barrels then.

As you can see above, I have modified my RODI to be a 5-stage system. I have 2 dual-monitor TDS meters. Any suggestions as to where to plumb them into the system?


I used silicone to attach the center panel to the back glass. Assuming it holds nicely, I'll tackle the other two over the next couple of days - I have actually used up my PVC, so I only have enough to do the 4 braces so it's one panel at a time :D

The shielded wiring that I ordered for my VFD still hasn't shipped yet, so that project is on hold. In the meantime I picked up a used Euro-Reef RS-250 skimmer. The pump is toast, so I'm thinking about a Bubble Blaster. Would the 3000 be sufficient size for this body?

It's next to the skimmer that came with my tank... outrageous difference in capacity. I'm also considering doing a recirc mod on this thing. Any thoughts around that?

Thanks for your input...
 
Nice build...I like the custom stand...

Thanks. The guy who did it builds them as a hobby - he's trying to start a coral store but is financially limited right now, so doing things like this helps him out a lot.

I tried to convince him and my wife that I wanted the stand SHORTER. I'm so glad that they overruled me, as it's barely tall enough now for what I need. I would actually be happier if it was 3-4 inches taller. Same with the hood. At least they both work well :)
 
All 3 panels are siliconed to the back now.

I have installed the barrels and RODI system is generating water. Unfortunately my 90 GPD still hasn't filled a 55g barrel 24 hours later. I didn't think it was that cold here in TX :(

Anyways, I hope to get some water in this thing over the next few days...
 
I have discovered that the valve feeding my RODI under the bathroom sink is leaking; water production halted until I can get out to the hardware store to source a new one. Still waiting on shielded cable for VFD...
 
Everything looks great, especially the rockwall. Thats gonna be a nice upgrade on the skimmer. I'll be tagging along.
 
After me being silly and not properly measuring the fittings, a return trip to the hardware store has the leak repaired. The RO/DI is not producing the expected 90 gallons/day due to water temperature and lower than quoted pressure, so I ordered a piggyback cartridge for it.

The second barrel should fill today, and I hope to dump the first batch of water into the tank tonight. With luck it will be full by early next week.
 
As you can see above, I have modified my RODI to be a 5-stage system. I have 2 dual-monitor TDS meters. Any suggestions as to where to plumb them into the system?

I would plumb the two reading spots pre DI and post DI resin. This will help you determine when your sediment filters and DI resin need to be changed independently. Great work so far by the way.
 
Thanks. I plumbed the first "in" to the water entering the system before any filters. The first "out" went just after the RO cartridge. I'm getting 0-2 TDS out. :)

The second "in" went after the DI bed and the second "out" is at the end of the system after the silica buster cartridge.

My only complaint is how little water it's producing right now...
 
Progress halted as the motor that I bought for the VFD control unfortunately does not have the right drive shaft for the pump head. I will attempt to source the right kind of motor and continue with this fun shortly. In the meantime I'll source a new pump for my skimmer and do a recirc mod to it.
 
New motor sourced and will be installed back into the system today. I'm still working with my LFS on a skimmer pump. The camouflage for the weir is done, but didn't come out looking like I wanted. I will take the wife's opinion on whether to install it or not. Hope to put the first batch of water into it tonight!
 
I installed the new closed loop pump after stubbing the plumbing, based on a recommendation I received. I also moved another of my plumbing lines to make some room over the sump:

I'm thinking about building an algae scrubber, and there's just no room anywhere else under the tank to put it, which precipitated the change.

The weir camouflage panels are installed. Here's a nighttime shot while I was testing out my lights:

I'm still waiting on my LFS to get back to me about the pump for the skimmer... but I did a test fit and boy are things tight:

Slow but steady progress... today I need to fire up the table saw and work on the eggcrate for the refugium. I'm going to have a DSB, benthic zone, a layer of LRR and finally open space at the top for macro algae...
 
I got a couple of things done today. I cut the eggcrate for the multi-zone refugium and installed it, started replumbing the refugium-to-sump siphon, located the heaters (I need some new suction clips), plumbed the durso-overflow siphon line and started on the closed loop intake pipes.

Tomorrow I need to plumb the water fill from my FSW barrel (thoughts? I'm thinking about putting a pump in the barrel with some tubing (with a siphon break at the top) and plumbing through the wall to dump water into the sump. The barrel bottom and sump bottom are at about the same level, so I think if I don't use a siphon break, I'll almost empty the barrel every time I fill... would that be consensus? I also need to get some proper screws to mount the VFD, and get a drill press so I can put some holes into the closed loop intakes.
