Pk's 375gal SPS Tank : from India

Dear Friends
I am from India and it has been my long time dream to do a larger tank with ultra-clear glass for viewing"¦ and now I have the right opportunity to do one as such and taken the plunge.
My current tank, just been 8 months old and the frags have started to grow and so has my thought on the larger tank
IMG_0050_resize.JPG


We have a lotta difficulties here in India with regards to sourcing fishes and corals as well the equipments. Over the years have got some good sources to get all my equipments in place so as to launch into this new venture and it has been real hardwork to get to learn this hobby and all thanks to Reef Central and my fellow hobbyists to make this learning experience a memorable one.

The tank will be a 375 gallon "“ 8' x 2'9" x 2'3" height tank with ultra clear glass on front and sides and regular on bottom and rear.

System: 375 gallons
Size : 8X2.75X2.25
Sump : 4X2X1.5
Additional Tanks :
1) 2X1.5X1.5 in line tank, that will be disconnected for water changes, semi automated water changes
2) 2X1.5X1.5 in line tank, with valves to disconnect from system and can be used for quarantine or for hospitalization tank
Both these tanks will have external overflow and will be connected to the main system.

Skimmer : SRO 5000 EXT skimmer
Phosban Reactor: Two Little Fishes Reactor
Carbon Reactor: Bulk Reef Supply Reactor
Additional Reactor : can use for anything else in future

Chiller : DIY 1.5 Ton A/c Chiller with Tempmaker's Titanium Coil unit

Return pump : 12500 Water Blaster Pump
Internal Circulation : 2 X MP40WeS, 1X6105 currently, will add two more MP40wES shortly

Overflow: Internal Over flow with Bean Animal's Design, 3 foot X 4 inches on the extreme left of the tank "“ this is due to problems in accessing the back of the tank on the right Side

Return : Two points one at the center of the tank ,and other at the extreme right end

Lighting : DIY Modular LED lighting of 8 panels with 24 LED each, might supplement with T5HOs if necessary. Shall do a detail writeup shortly on my DIY LED lighting fixtures and what are the modifications done in the system

Controller: DIY Aquarium Controller using Arduino and has been running in my system for over 3 years now with many updates. Currently saw an interesting post on DIY forum regarding a touch screen controller (but it was removed shortly) and I have sourced all the elements for that DIY and will shortly be upgrading my controller to that touch screen "“ that was a 3.2" screen, whereas my order is for 5" screen "“ going for a bigger tank might as well go for a larger screen to work with!!! Will do the build of that controller also on this thread


Onto my tank build :

Initially ordered 12mm tempered glass for the job and at the time of sticking the glass we found some undulations on the ultra clear glass and the work was not that good on the glass"¦ so had to return it and delay of 1 week for getting the newer glass which was 19mm (not-tempered)

The stand was made with four openings for later usage!! But I am not going to keep anything under the tank as I am moving my entire sump and all equipments on the back of the tank through the window onto the terrace on back.

This is where the sump and all equipments will be placed. Going to build a small 3 feet X 14' feet x 3 feet room for hosting all the equipments and tanks.

note the DIY Chiller unit (Titanium Coil) to be fitted with 1,5Ton A/c outdoor unit for chilling 2000 litres of water"¦.


The initial 12mm glasses with problems

The new 19mms man they are heavy needed twice the amount of man power to carry them the 19mms being carried in the tricky stair case to their final holding place needed 5 people to carry each of them, in the image u can actually see only 2 of them on either end, but there are 3 people on the inside, the reflection and bad photography made them partly visisble

Can see the 12mms on the inside and 19mms on the outside…the difference in size!

The Sealant used for the entire process “121” Aquarium sealant – black

The 19mms being rested on the stand over the 1” foam and the degreasing process

The Front glass kept on top of the bottom glass and is kept about 10mm from the front so as to have sealant on the front side and inside of the front glass for more strength
interestingly, the sealant is applied at the joint as shown,

and the front glass is anchored and lifted from the back so that the glue is applied to the entire bottom of the glass evenly and fixed firmly to the bottom glass

making sure it is 90 degrees

side glasses:
glues on two sides, the bottom process is same as above

I hope u can see the 3 X 1.5” holes on the left side of the rear glass


it took a total of 4 hours to get this up and going and whola finally it is done. Thanks to Allister for this job done excellently at the time and spec that i needed... he needs to come back again to get the overflows and support strips done as well as give the tank an excellent finish

Will take another day or two to get the support strips and the overflow box in place…

Will post the update on the rear portion work where I will have my sump and other equipments in place…


Will keep updates coming…

The Rear Area Build:

I am not very good in google.. but i think i can get what i want to show you all for help...

making two compartments of 6' width and 8 feet width of another and the brick work as shown...
the center brickwork will be broken to allow pipes to go thro from each one so that i can get more setups +/- tanks and equipments

I am not able to get the plumbing diagram in place...

The Brick work

The Sump and Extra tank for water change
reef+outer+setup-2_resize.jpg


another view

The system of plumbing:

RHS of the Sump is my return, the return pump will be 12500 Water blaster which will take the water into the tank with two outlets into the main display tank - going to put a tee at the output and a valve to take it to the chiller shown by a cylinder near the W/c Change, chiller to the return area of the sump.

Drain - will lead into the sump as well as the w/c tank, overflow from w/c tank into the sump... a valve at the drain near the w/c tank when closed will take the w/c tank offline and the entire water will be sent to the sump. Using a valve (shown by a small pipe) in front of the w/c tank, water will be removed from the system and new water will be added, open the valve to make the w/c tank online.

The same system will be used to the other tank also, and same method for offline and online... when offline it will be made as a quarantine tank, and online it will be a frag tank.

1 pump will be used to send water into the reactor;s and out of reactors into the return area... all reactors will be serially connected
 
I am stuck now with regards to the bracing on the tank
The tank size is 96X33X27 Height. (8'X2'9"X2'3")

I have already put 1" bracing along the length at the bottom of the tank for extra support.

do i need bracing on top?

The plan was to do a center bracing of 5' width X 4" of 19mm glass on the front and back, and two length bracings of 5" each on the ends of the 5' bracing, but under this scenario, at the center of the tank i have glass comming down to about 40mm (2X19mm + silicone) and dont know whether will that be nice.

kindly help... if i dont need bracing then i can go rimless and thats what i want!!!!
 
PK - really cool to see the build come to fruition. I'm following along for sure. Thank you for the updates.
 
My name is Ashish and I live in the US....I always wonder how someone from India could possibly have a reef aquarium!!. We have the LFS and online vendors and have supply and live corals and fish delivered to our door the next day no questioned asked. You must have to endure so much more to enjoy this hobby; I have a lot of respect for you. Your friends and family must think you are crazy... Don't worry my family thinks I am mad 2 lol. But I can't imagine the looks of people in India who are fortunate to see such a sight. I am curious where do import your live stock from? Are there any shops in india that sell marine fish and corals?
 
Nice to see your build PK,if you need any help from neighbouring Dubai send me a PM.
Glad to assist.
 
PK - Glad to see that you are able to get all parts required to build a reef tank in India. My name is Anand and I live in the US; but originally from Trivandrum. Just like Ashish my family as well thought I was mad when I started my tank back in 2008! But as time passed people really started appreciating it as it grew into a fully mature SPS reef tank.

Good luck!
