Project Quiet River Shrimp Rack

[Navanod]

Hi bros,

A sneak peek at what's happening .

This just arrived over the weekends from Fishy Business, a 4ft x 2ft x 1ft triple tiered rack


Top tier is a mirror of the 2nd tier. Bottom tier is a sump box


The aim of the project is to start a dedicated shrimp rack.
I wanted it to:

1. Be quiet. So no airpumps, noisy overflows and water splashes.
2. Have good directional water flow, similar to how a river would cascade & flow.
3. Have good surface agitation and skimming to promote oxygenation.
4. Runs off a single chiller.
5. Use minimal soil in the tank (use the sump instead for pH control).
6. Be as fail safe as possible, especially against flooding.
7. Have separate dedicated canister filters for both tiers. Over-filteration and a large water volume is the key.

The trade off of course is that the entire rack will also share the same water parameters, and if anything goes wrong, I may lose the entire rack.
The achilles heel of the rack is the chiller and its associated powerhead. If that fails, there's no backup.

On paper, this is the design.


Now, its time to work on the DIY PVC pipings!



Stay tuned for the progress and the list of equipment...

woot!!! im first to line up! more poison please!!!

[xconnect.]

Wow all the best man keep the poison flowing and do up date us with pictures

[alvinchan80]

Serious poisoning in progress... Keep updating your set up...

Seriously lots of partitions to do culls.. Hahaha..

Another big project coming up. Looking forward to your tank updates.

hoho..what is this man...a double storey mansion for shrimps?

[rolex]

Another Impressive set up.
Nice design.
Please share more pictures when cycling tank
Happy shrimping all

[Ecalyte]

Very very nice man.. hope to see more pictures soon!!

[newlife]

Wow wow.....BIG BIG PROJECT man...
Waiting Waiting for it to move it move it...

[Noobz]

Drooling. Can't wait to see your setup.

[Apistoinka]

Can't wait to see whats the outcome... Even I don't keep shrimp but I'm excited to see the setup...

[BFG]

Er, why do you need 3 set of pvc pipes per tank? To complete your setup, get an auto top off system and a pail to store ro/di water for automatic water top up.

another amazing project!!!
Good luck bro!

Looks really complicated man! Camping here

Thanks bros for all the encouragements. I'll explain some of the design as I go along with the project log. This weekend will be the PVC assembly and I'll explain the 3 pipe design and where I stole it from :-)

[Jovel]

Autocad? awesome bro looking forward to your progress. And you really got to get a big *** chiller to power it all. Good Luck!

I think the three piping is to simulate even river flow to the zigzag pattern of your tank

[Mafia00]

wow! a big project, must have plan it very well before ordering the tank.

Cant wait for more updates!

[rascal]

nice!!! good luck bro!!!! post more pic...

I think the three piping is to simulate even river flow to the zigzag pattern of your tank

River current is possible with 3 incoming stream of water but how to zigzag when the bulkheads are inside a single-end partition and flowing from it??? Best one can achieve is even flow only to the 1st shrimp partition.

I'm with BFG using one main out-pipe but if you look closely (left end of middle tier tank), Navanod's design has 1 PVC in-take elbow facing up and 2 facing down ... *very puzzled*

Both halves of all usable partitions are based on under-flow, passing through a narrow partition, before over flowing to the end-partition and down to next tank, not directly to sump!! IMHO, that essentially means most bio-loading from top tank is added onto 2nd tier... hmm...

Navanod, since your inflow is based on overflow from 1st glass partition, I suggest you check & double check the floor's leveling because that will influence how much water flows into each half of each tier. Confused? I am too

2. Have good directional water flow, similar to how a river would cascade & flow.
Hate to pop your bubble but even-flow, not directional, is only for 1st shrimp partition. A height difference (from inflow partition to tank's water level) will not prevent shrimps from climbing over.

3. Have good surface agitation and skimming to promote oxygenation.
Under-flowing partitions are never known to have surface agitation unless you have a rainbar running across all shrimp partitions ...and skimming is possible only with overflow, not underflow.

5. Use minimal soil in the tank (use the sump instead for pH control).
Judging from the diagram & image, you will need a generous amount of soil to close the partition's bottom gap, which doesn't prevent shrimplets from crawling through.

6. Be as fail safe as possible, especially against flooding.
That depends on how quickly the underflow gap gets clogged up (then you'll have free overflow over shrimp partitions) and how you control water level in the sump.

7. Have separate dedicated canister filters for both tiers. Over-filteration and a large water volume is the key.
Which means 2 canister filters, plus a big-butt return pump, which takes another toll on the chiller...

D@mn... I'll be waiting for updates!!
