eviltrain's Shrimp Rack Project Alpha

some updates

front view

top view

my over flow box which links to the under gravel panel is done last night ( silicone/super glued) and left to dry. the concept will be the same as the bottom tank. i will post more photos tonight.
Water which passes thru the undergravel panel will be siphon into the main box at the back.a acrylic plate is holding the 3 containers together and sits on the part where back panel and the centre partition is. two J-tube will be using for the siphon effect.
water testing will be done tonight.
-wish me luck-

wow u really know how to DIY...if its me I dun think I know how to do it.

Now waiting for my connector for chiller to arrived then look for 1 more tank to start my setup, still think how to run my 2 tanks wif 1 chiller.

[eviltrain]

bai, your 2 tanks is side by side or top bottom layout? need help can sms me at 9o45o543.

Hi,

Interested to see how you intend to suck the water into the 3 DIY-overflow and how does it flow out. What is your purpose of DIYing this overflow ?

[eviltrain]

Oh, i forgot to take the side view and with the J pipe photos.
the purpose of doing this over flow is to get the water which had passed thru the under gravel panel to go to the bottom tank.

Bro,
Really admire your design and ingenuity! Can't wait to see how the final setup will be like

One thing though, I don't really understand the principle of your overflow system, how does it sustain continuous water flow? Appreciate if you can briefly explain the concept

[eviltrain]

as you can see from this picture carefully, from the shorter container, there is a circle i drawn using a black marker ( which i have already melted out using soldering iron, remember not to breath in the smoke ). its already partition with a 2.5cm hight 2mm thick acrylic at the centre ( look like this" |o|_|" ).
Tank water will flow in from the under gravel panel -> clear pipe -> elbow pipe connector-> hole of the shorter container.
As water rises, water will over flow to the next compartment ( this is where the J pipe will be ). for this case, either i will pre fill the J-pipe with water first, or make a hole at the center of the J-pipe( attach/glue air tube connector with a length of air tube ), suck the air out for the siphon effect to start.
the siphon part is not finalized yet. so there may be "eviltrain over flow system 2"

-thanks for viewing-

Wow. Very impressive DIY there. Eviltrain, you are good.

My tank layout is 3 tier stand. Below tank finish cycling waiting to add shrimp liao.

Middle tank now empty, top tier need to buy a tank later when my connector for chiller come, still think must use wat flowrate canister for my this 2 tank setup.

[eviltrain]

must see the tank size too. 2 feet? if standard 2x1x1 feet tank.
1 tank will be around 56 litres.
you need a canister which can filter around 5 times per hour.
3 tanks will be 168litres. 168x5= 840 litres per hour.
a ehiem 2222 with flow rate of 950 litre per hour will be enough.
but for filteration, the more the better.

[monster_88]

May not have fully understood the concept . But, do you foresee a problem if there is a short stoppage of the pump? Will the overflow restart automatically when pump is restored?
Can't wait to see your final test run cheers

My tank size is 3ft X 2ft X 1ft water height for the 2 tank I think to do. water volume per tank will be 170L.

170 X 5 times = 850L ~~~~~ ~~~~ 850L X 2 tank = 1700L per hour

siao liao like that I need to get Ehiem 2080 liao.

pocket big big hole liao.

[eviltrain]

for CRS only or what?

[eviltrain]

Ok , great. my Overflow Box Version 1 has a major flaw, the side did not sticks well ( super glued ).
Well, i guess i need another trip to Daiso and Artfriend to get the containers, acrylic board , acrylic corners and choroform over the weekend

i will change to simpler over flow pipe system, lesser drilling, better siphon.

Bro,

Frankly, I don't really know how to calculate ideal flowrate / water turn over rate for an aquarium. But, based on typical setups, I believe most people may only be using either 2026 / 2028 (which is about 950 - 1050 before medias) for keeping fishes in 3ft tanks. So, I suppose 2028 may be good enough for you. Just my thoughts

Ya I using 2026 to run my 3ft X 2ft tank wif chiller. But now I need to run 2 tanks of 3ft X 2ft wif 1 chiller so dun know which canister to use.

for CRS only or what?

Yes for CRS only

[eviltrain]

wah, brother bai
you having bigger project than me
your case will be overflow box/pipe also.
schematic will be :
filter outlet -> chiller inlet -> chiller outlet -> top tank -> over flow box/pipe -> lower tank -> filter inlet.

3 x 2 x 1 = 6 cubic feet
12 cubic feet = 170 litres
2 tanks = 340 litres.
you need at least 1/6 horse power chiller to cool 340 litres of water.
as for the canister, you need 1500-1800 litres per hour at least.

[monster_88]

wah, brother bai

3 x 2 x 2 = 12 cubic feet
12 cubic feet = 340 litres
2 tanks = 680 litres.
you need at least 1/5 horse power chiller to cool 680 litres of water.
as for the canister, you need 1500-1800 litres per hour at least.

Not sure if I read something wrong, but if the tank is 3 by 2 by 1 (instead of 3X2X2) then for both tanks will be about 340litres only. Then maybe a 1/6 chiller might be enough.

Anyway, 2 3ft tanks for CRS!.... cool .... very luxurious

[eviltrain]

haha, sorry see wrongly

[monster_88]

Ya I using 2026 to run my 3ft X 2ft tank wif chiller. But now I need to run 2 tanks of 3ft X 2ft wif 1 chiller so dun know which canister to use.

Just my personal opinion. I believe if you just add another 2026/28 to pump from bottom to top tank will be more than enough. Only one canister need to be connected to the chiller, the water will circulate and balance off eventually.
I think this may be an easier and cheaper option.
