Project Quiet River Shrimp Rack

[karlyau]

may i know where you bought the fine stainless steel mesh? been looking for it for some time

[Navanod]

I got the mesh from bro Jojoe. You can pm him to ask him if he still have more

[karlyau]

ok thank you so much for the info

[venom]

had been looking into this thread.
can't wait for the finish setup.
keep us updated.
Thanks.

Finally done with the piping! Alot of minor cockups that I shall not bore everyone with, lets just say, check your purchases carefully at the shop and measure twice, cut once.

Bottom tank to IKEA sump, hahaha. Its about 2ftx2.5ftx1.5ft, quite large.


Top tank overflow


Bottom tank inflow from top tank


Now for leak testing and deployment of the pump, Eheim 5000+


Oh ya! Ronwill, I checked


Damn leveled, have to give it to Fishy Business cause they did the stand. Thanks Roger

Stay tune for wet pic and construction of mesh filters

I'm also looking at being able to "reset" a partition by sucking out all the soil from it easily, which is why I'm trying to keep it minimal.

Perhaps a removable tray for the soil would be good? That way you can move the soil out easily without much fuss. I had a small box with peat moss as the base along with a simple layer of quartz gravel on the top. Grew a Cryptocoryne in that box for quite some time. Good to see that the system is coming along fine. The drainage hoses are huge.

Seeing the IKEA box brought a smile to my face. I almost bought one as a fry tub some time back.

I'll probably have the bulk of the soil in the sump, hehe. The in tank soil will just be enough to hide the glass bottom so the shrimps don't get stressed.
Those hoses are HUGE indeed...had to use the saw I used for cutting the PVC pipe to cut it until I found a strong cutter!
IKEA no longer sells this type of storage box now...the one they have now is smaller and more cheapo...

Some updates!!

The overflow system works!
A video speaks a thousand words, sorry bout the poor videography skills and sideways vid
http://youtu.be/ptv_GzFKDNg
Towards the end of the video, you'll hear another "click" as I turn off my room fan. Notice how quiet it is? Yeah~~!!!

One of the flowpipe is not airtight and I get some bubbling occasionally but its not loud enough to be worth going back to silicon everything...will play by ear first. Now to let it just run and clean itself, notice the filter bag in the sump? Its damn dirty...even after wiping the tank like mad, there's still so much dirt.
Will drain the entire thing and refill in a day or 2.

Now to work on the partitions!
After trying countless prototypes...


The triangle shape suggested by a bro was best...credits to my wife for making refinement to the design by inverting the triangle


Front view, looks like tennis court Hhahahaha


It then took an afternoon to refine it to the point where the sides are sealed and nothing can sneak through...tried the airhose method but its not able to cover the gaps caused by irregular silicon at the corners. In the end, sponge was used.


But this is just UGLY as hell!! almost wanted to just silicon everything but I needed it to be modular...

[Navanod]

Then a breakthrough came! Zipties was used & it worked! Quickly covered the mesh skeleton with the actual fine mesh meant to only block adult shrimps (not shrimplets) and tried a new method of securing the sponge so it doesn't move when compressed. Voila!




Riding on the success, I tried to do the same for the SS fine mesh that will block even shrimplets. And realized that the same method of zip ties cannot work! I can't fit zip tied through such fine mesh! But in the end, a secret method was found, hehehe


Almost done on this side, just need another adult shrimp partition inbetween the 2 SS mesh ones


Found a problem...one of the glass partition panel was set too high and cut off the overflow, and killing my plans for surface skimming. I then remembered the famous air hose! Slip it over the end overflow and it raised the overall water level of the tank slightly, allowing water to overflow that high partition

Thanks again ET bro, for the airhose idea. Hahahaha!

Now to do up the overflow partition meshes...

[Navanod]

Fixed the sideway video, now its right side up, hahaha


The background noise was my room fan...

'pretty pretty no run water' already bro... Haha...
Soon your shrimps will flood the tanks...

[sqwerc]

Great Work!

[Navanod]

'pretty pretty no run water' already bro... Haha...

But tank cannot flood the room first! Haha! Top tier fully booked liao. Haha, now thinking what to put on bottom tier

[xconnect.]

What u thinking of putting?

[Navanod]

What u thinking of putting?

Already have CRS, fire red and maybe BKK?

[Navanod]

Darn, there seemed to be an LFS-wide shortage of black soft fine sponge!


Only can get the coarse type of sponge...


gonna try using black wool but I doubt it'll work.
Already checked C328, Polyart and some of those wet market LFS in Tiong bahru...anyone know where to find?

[Navanod]

Sorry for the lack of updates!

The rack had been running in over the last 2 weeks and nothing really exciting happened. Will share some pictures later

I just installed the chiller onto the new rack last night and it took 2.5 hours to cool it from 26.2 to 25.2 degrees. However, the strange thing was, after the chiller stopped, temperature continued to fall slowly over the next 1 hour, all the way to 24.7 degrees. Most likely, the water volume and the partitions in the tanks causes water to mix very slowly, which was why even an arctica chiller cannot sense the correct temperature quickly enough.

Best part? It took all night (6+ hours!) for the temperature to climb back to 25.2! The chiller will only kick in again at 25.7 (0.5 degrees above set point), so looks like it'll actually swing between 24.7 and 25.7 although I've set it to cut off at 25.2 (don't know why i set at this odd number, I just got tired of waiting when it was stuck at 25.2 after more than 2 hours).

hehe, ever consider modding external probe for your chiller? and place it in the last compartment?

I actually have temperature controller on standby (because I am planning to also chain a fan to also kick in to vent the hot air out into the living room when the chiller kicks in).
The arctica's sensor worked so accurately on my 2ft that I didn't think it was necessary to install the controller...looks like I'm wrong...haha
