Yet Another Oceanic 90g Tech Tank Build Thread!

After lurking these parts for more than a few months and learning more than I thought possible, i've finally decided to post the progress of my very own mixed reef build.

I should state that i've been out of the hobby for over 10 years, but "back in the day" I had a 50g reef...... However, the technology has changed so vastly, as has the overall philosophy of tank keeping that I definitely feel like a noob all over again. Luckily, two of my brothers have actively stayed in the hobby (and also are RC members) and have guided my back in. In this build we have collectively worked together on hardware selection, tank/sump/stand design and build, and our general approach to things. My one brother designed and built the stand (and generally anything with the carpentry....awesome job I think) and my other brother helped out with the drilling of the sump tanks.

The general idea, however, was to forgo the standard stand concept and build it into the wall in our finished basement. Pretty much *the* selling point as far as the "house accountant"(my wife) was concerned.

Anyway, here are the first round of many pics and a description of what will be used in the tank..... I figured this was as good a way to make my first post as any........

Description of Parts:

90 gallon Oceanic Tech Tank
The Filter Guys Ocean Reef +1 RO/DI
Tunze 9010 Skimmer
Current Outer Orbit 2 x 150w HQI, 4 x 54w T5 HO Actinic Lighting
Iwaki WMD-30RLXT External Return
2 150w Jager heaters
3 HK 4 Powerheads
Sybon Refractometer
Mag5
two 20g high, one 30g long custom sump
piece of foam directly under the tank for level purposes (it works!)

and a ton of other assorted plumbing, lumber, and odds n' ends.

The base tank....just waiting to go somewhere:

The sump, I forgot to mention in my initial post is going to be comprised of two 20g high tanks and one 30g long tank. All drilled and gravity fed (as you might be able to see in the pics). Plumbing is just in the starting stages....bulkheads in, and basic design all set......
 
Andy,

Per my email I would personally get rid of those tanks that cracked.

The thin glass and location of holes drilled (from the top of the tank) coupled with the over-tightening of the BH probably caused this.

Depending on the length of the crack you might be able to get away with an Automotive Windshield Repair Kit. They fill in those cracks very nicely and basically bring any windshield back to "spec".

But the best thing to do is to replace them. Personally, I'll drill them in the same locations and we can hand-tighten the BH's and use aquarium sealant.
On my tanks I did both (tightened down AND used sealant) but my glass is much thicker in the sump.

Or maybe we can do this (to be extra anal and safe):

We could drill out the BH's much lower and use a 90 degree elbow fitting on the inside of the tank to "create" the water level in that tank. That way we can drill in a place that we feel comfortable with and then create an overflow of sorts.
 
What my brother is referring to in his above post is a little surprise I discovered while settling in to do some plumbing last night.

I'll put up a diagram soon as to the sump design but basically, it is a 3 tank 70 gallon sump design. The tank overflow flows to 2 of these tanks......think of all 3 set in a row next to each other. The tank flows to tanks 1 and 3. Tank 1 is the "skimmer" sump. Tank 3 is the fuge/dsb. Both tanks 1 and 3 then flow to tank 2 which is the 30 g long "equipment/return" sump. Tank 2 also has an "emergency" bulkhead at the top that in case of power outage, if the water level ever reaches up to a certain point it will flow out of this bh through plumbing and into a basement well sump. Follow? lol.....

The drilling of these tanks went well, although we were very close to the top....there were no cracks. We initially hand fitted the bulkheads these tanks, but I later on tighened them up a bit more. They seemed fine, but when I went last night to start plumbing I had noticed a couple cracks in one 20 g and the one 30 g tanks. The other seems to be fine. Anyway, here are the pics of them:

Glass, cracks and water can only equal one thing in my eyes...

impending disaster. It may not be today, it may not be next week, but I would lay awake at night wondering when it was going to happen.

Replace those tanks, IMO. Cheap insurance I would say.

Also, are you planning on removing or covering up the fiberglass insulation in the walls? Seems like it may be a sponge once all that water/humidity starts flowing.

Without question......... My brother just knows that i've been going to the "house accountant" for "additional expenditures" alot lately ;) But in the end he was telling me that even with attempting to repair, i'd never have full confidence in it and i'd be checking constantly. I tend to agree......lol.

So we pick up a couple new tanks, re-drill and have a more gentle hand next time ;)

And yes, the insulation will be dealt with......either completely removed or covered up. More than likely the latter. All of that was going to be dealt with, we were just finishing up the basics of the tank and sump stands and beginning the plumbing before we hit that one. I still have electric and the ro/di to mount (it's currently sitting on the house water pipes in the room) on the wall as well as many other room design details. As far as the insulation goes, not only would it swallow water, but also I dont like the potential for it to introduce contaminants. So it will be covered or removed....without a doubt! :)
 
Very cool - I'll be tagging along.

I've been researching the Tunze 9010 skimmer to replace the cheesy Sealife Systems skimmer that I have. The Tunze is the only one that will fit in the skimmer section of my homemade sump/refugium, but not very many people appear to have them.

I look forward to seeing how that skimmer works for ya!

Good luck!
 
Maybe turn the insulation around and cover/seal with heavy duty plastic.Or possibly replace the existing insulation with that 1 1/2 foam board stuff?The latter would be the best.I like Nater's idea,drilling a little lower and installing a elbow overflow on the inside of the tank to dictate the correct water level.Keep the wife happy and dry and replace those tanks,cracked aquariums make great turtle/snake cages;)

Yup.......sounds like an idea on all counts ;) Those cracked cages will work well for a bunch of stuff......turtles and snakes included! Yo....get the wife to go to the job fair this weekend........

So what i'll be doing now with the project is mount the RO/DI unit, install the booster pump, auto-topoff and work on the overflow until I can get the replacement tanks and drill them (either me or nater...not sure yet)

My next decision, however, is sand. I've been reading all the threads (and subscribed) and am really trying to avoid the petstore sand price gouge. There seems to be a lot of support for Pulverized Limestone as being a good, inexpensive alternative. In essence it *is* Aragonite. Just not 100% sure yet.......

Thanks MR PALM BEACH and Reeftanks6 I spent a lot of time researching that tank, but lukin and nater really got me thinking away from typical stands and more into the in-wall custom sump/stand design. Both of them have amazing high volume sumps and I knew lukin could make the stand far better than I or Oceanic could ;)

Stay tuned, i'll be taking pictures at every step of this project...... I'm glad to finally be getting back into the hobby :D

Ok....I finally mounted my Ocean Reef +1 and installed its' booster pump and tested for functionality. All is working extremely well, the RO/DI is out of the way, neatly on the wall and the psi has gone from 40 to just under 100.

Anyway, here's a pic.......

yo dude,

Call me when you have the tanks. I can drill them out and get fittings at HD to allow us to drill in down in the middle. As a matter of fact, I've got SLIP fittings/elbows so we can do it.
 
Yup.....plumbing is all done, now I just need to mount the Outer Orbit Lighting and i'm ready for a water test, sand and rock.

Give me a call when you have some time.......

I'll put up some more pics soon.
