Not that crazy about the chaos of corals on the sandbed, but everything sitting on the rockwork is to die for.

Congratulations Sanjay, lovely tank. I am in the process of building a 280G myswlf and have been debating with external and internal oveflow boxes. It would greatly help if you can please give some more details on on ur overflow box design details and plumbing !!

Congrats Sanjay! How long have you had the Chaoti's Wrasses? I would love to try one but I have been hesitant due to their poor survival rate.

Sanjay
08/05/2010, 11:05 AM
Thanks everyone for the kind comments.

@ ojafri: The overflow box is basically a 3 sided tank attached to the back of the tank, in my case the dimensions are 7ft long X 12" tall X 8" wide. The bottom of the box is drilled for 2 2" Durso type returns. The back pane of the tank has a cut out at the top for water to flow over from the tank into the box.

Keith: Unfortunately, the chaoti did not last long. I had just got them when I started writing the article in June, and when I got back from my trip to Israel in July, they were gone. Beautiful fish, but they seem to die even after eating well and being in the tank for a month or more. Will try them one more time, before I give up on them. They are one of my favorite fish.

Thank you for sharing your beautiful tank with us! I found your write-up to be very informative, and am glad to know that AEFW are not necessarily the end of all.

Your tank truly deserves to be in the spotlight. I wish you a wonderful 20+ more years in the hobby!

Sanjay,

Very, very nice setup and write-up. I will be referring to your write-up when I set up my new system. (Everything died (all fish, all corals) in my recent move (cause still unknown, but I have my theories), and I will be rebuilding bigger (200-300 gallon size) and better. I, too, have always preferred a more natural look and never done a wall-o-rock configuration, and the structure you assembled looks great! Also, I, too, prefer pairing a select few over the menagerie approach -- especially where that menagerie approach combines species from Atlantic, Pacific, and wherever else. (By the way, give those scooters some privacy! :) ) I will be consulting your info for lighting especially. Also, I, too, finally have a fish room with water supply and drain (utility sink) in place, such that I can set up to eliminate lugging buckets up and down. Your setup is a nice blueprint for what I had in mind to do, too (using SpectrPure auto topoff system fed directly from the RO/DI unit, but a dual tank system to mix new saltwater high, then gravity feed it into the sump when doing water change).

All in all, very nice, and congrats!

(By the way, one of the Orbitech patents is being re-examined (no substantive action on the merits, but that will be coming soon), and there have been office actions in connection with pending applications that finally apply far better art than before, and I am watching with great anticipation to see how OT tries to respond to them.)

Quite unbelievable and inspirational!

I have heard your name before but never run across details of your systems. My reef tank philosophy and design is very similar to yours. I only wish we could "simplify" it even more.

I do have a couple of questions that did not seem to be touched on in your write up.

1. I did not see where you are running a refugium. Have you ever run one before and what is your basic reasoning for not running one now?

2. Most people in this hobby would say that you have a ridiculously small amount of live rock for this size tank. Not me. ;) What would your answer be to someone who told you you need to add more rock to your system?

3. You did not mention your methods for controlling temperature and humidity in your fish room. What systems do you have in place for this? This is one of my biggest battles.

4. If you had to guess, how many hours a day/week do you think you spend physically doing maintenance chores on the tank? Not including Internet "research." :D

Thank you again for your time to answer our questions and congrats again!

HI Sanjay,

Very nicely written piece about your journey into marine and reef keeping. Very inspiring too. The coral photographs are great. Promised myself that after reading your article will get into reef keeping. Definitely will.

Look forward to you gurus for inspiration.

Keep up the good work.

Cheers and Congratulations,

Vijay.

Hooray I have the same pendants as the industry proclaimed lighting expert! Never before have I felt so good about that purchase as I do now. :D

Congratulations on TOTM! I've always wondered what your tank must look like. What a fantastic write-up too. Its unfortunate that not enough people go into that much detail when they receive this honor.

By the way I absolutely love this acro! Hopefully something like it is available in Canada...

1. I did not see where you are running a refugium. Have you ever run one before and what is your basic reasoning for not running one now?


I have never run a refugium in this system. I used to have one with my older system, but never really saw any major benefits and it just created one more system to maintain and deal with. It is helpful in some situation but to be useful for a system as big as mine, it would have to be big refugium.


2. Most people in this hobby would say that you have a ridiculously small amount of live rock for this size tank. Not me. ;) What would your answer be to someone who told you you need to add more rock to your system?


I would rather fill the tank with large growing corals than liverock :D. I like the idea of creating rockwork that facilitates water flow and provide room for the fish to swim. With the sand bed, there is enough surface area for nitrifying bacteria. I think the aquascaping has more to do with the negative open spaces than the spaces occupied by rock.


3. You did not mention your methods for controlling temperature and humidity in your fish room. What systems do you have in place for this? This is one of my biggest battles.


The temperature in the basement is not much of an issue, the room has a heaters for the winter. The humidity is a bigger issue, and I should have mentioned it in the article. I use a heat recovery ventilator (HRV) that brings in air from outside and exchanges it with the inside air. I use a humidty switch set at 45% humidity to turn the HRV on/off. This has helped reduce the humidity. During the real cold parts of winter I run a dehumidifer to reduce some of the condensation on the windows.


4. If you had to guess, how many hours a day/week do you think you spend physically doing maintenance chores on the tank? Not including Internet "research." :D


The tank is pretty much on auto pilot. I spend about 15 min a day feeding my fish and any glass cleaning it may require. I spend a lot more time just looking and enjoying the tank. On the weekends, i spend may be an hour when i do more work on the tank, eg. blasting the corals with turkey baster, checking chemistry parameters, or changing out the carbon, etc.




Thank you again for your time to answer our questions and congrats again!

Are currently using Zeovit or any form of carbon dosing?
I was told you used Super Glue to stop the leak on the aquarium. I suppose it work well.
These are good things to know, just in case:)

Thanks

Yes, I am using low dose of zeovit to bring down the nitrates and keep them there.

Hi Sanjay,
Wow your tank is great, I just hope that I can imitate part of what you have done. I am currently working on a 300gal. Where can I find more information on how to do the type of aquascaping with the acrylic rod and drilling of the rock. Your write up was excellent and I will be coming back over and over to learn as much as possible.

08/12/2010, 11:08 PM
very nice Sanjay, I agree with your viewpoints on general reefkeeping and enjoyed reading your writeup, 20 years of experience goes a long way, I particularly like the way you delt with AEFWs, also interesting to learn about your experience with rising nitrates and not seeing any drastic outward effects from it

I do have a question. You are using 6 vortechs but did not mention them in your maintenance routine. I would think in dwelling propellers in seawater would need regular cleaning to maintain their spec ratings. How often do you clean them?

Thanks for your very thoughtful remarks. Absolutely stunning display! :thumbsup:

Great write up Sanjay.What did you use to attach the overflow on the tank.
Did you face any ssues in having such a big over flow.You mentioned keeping new fishes fishes and corals in the oveflow like a QT but did you face any risk of spreading disease to the DT.

I am a great fan of yours and so is the reefing community of UAE.Keep up the good work.

Wow, VERY nice tank and an even BETTER write up! It is always nice to read how exactly reefkeepers have gotten their tanks to where they are today, including the lessons learned from mistakes and/or inevitable "hiccups" in their journey. Also going into detail on exactly the type of equipment used and the reason behind using the equipment was EXTREMELY helpful in potentially applying your design to something I might do in the future. I think all of us strive to spend less time below the tank, and more time in front, and it is definitely reassuring to see that you've been able to do that on such a large tank!

I think the biggest task I have now is getting my wife's "approval" for such a large tank :D

Again, great tank, great write up... very inspiring!

I do not really have set schedule on when to clean them. I typically clean them when I feel they are "dirty" enough to need cleaning. It is usually several months between cleanings. I clean mostly when I see the intakes getting closed up due to algae, or see algae growing inside the wet side.

Sanjay I have followed your entire tank build from page one, I was wondering when this tank was going to get noticed !

Just a few questions
1) Are you still doing just one monthly water change or have you altered that in any way?
2) Do you adjust the Cal, Alk, Mag levels of your premix SW before adding to the tank?

Looking forward to more pictures in the future.
Congratulations again

Congrats on the tank of the month.

At what which temperature do you find the best growth in your tank? I see that you keep different temps for the summer and winter.

Temperature: 78 - 80 F (summer); 75-77F (winter) (apex controller)

Congratulations Sanjay. You have an wonderful aquarium. Nice to get to know about a fellow reefer from India. I too had tropical freshwater aquarium back in India. In fact my mom still maintains it there and is having an Angel fish that is there for more than 10 years. My dream to have a Saltwater reef aquarium was realized after I came to the USA.
