Yes yea Nyos 160 value at 800 bucks look pretty cool. 

 

Will 6mm thickness sump be advisable for a marine project?

It seems like you remove all the glass panel and redo the entire compartment.

It helps a lot thank you for the detail explanation. I wonder how you manage to clean up the sump totally no calcium residue at all sparking clean.

Appreciate the questions as well. Also seeking feedback if i'm doing things wrong.

The sump glass isn't all that clean actually. Some calcium stains still present despite using ph ~1.5pH oxalic acid to clean.

Frankly, a good penknife blade + wetted surface is the easiest.

A 6mm sump is alright if its about 2-3ft in size. Thin glass (eg 6mm) has the risk of cracking with hard knocks.

The original sump design would probably work just fine. But i added acrylic panels purely for the fun of DIY.

Just wondering would this setup of the sump be OK?
What do you recommend?

This is a n30 fw sump.. Totally the same as mine. The issue is the centre compartment is too small for skimmer.. Need to re partition the glass panel..

I will reply in the other thread you started so its easier for folks to follow.

If you want to overhaul, you could DIY repartition like Edmund did (thumbs up) or get a new sump.

For reference, I made a 2.5' sump previously for ~ $120+ from Atlantic Glass (2 years ago). Prices may have gone up a little. Refer to "My Slice of Nature Part 1" thread.

Thanks I will take a look.

What will you place after the skimmer compartment ?
The compartment where the skimmer is will have bio media, basically whatever i have accumulated from my current tank will be moved over. (marinepure block, marinepure block, siporax, bacteria king)
 
The 3rd compartment will be a refugium. The underflow area is covered with a netting to prevent fishes from getting into the return pump section. As the name implies, it'll be a refuge area for injured fishes (if any)
 


My suggestion instead of using net, some fish can be trapped by net, you might want to consider sandwiching the underflow glass with 2 pieces of egg crate and glue it secure. Will block fishes passing through the underflow portion and yet do not trap fish and block water flow.
Just a thought.

I had some queries about the overflow. Its set up as a Herbie (not Durso as mentioned earlier).

With a DIN 40mm pipe (1.31" internal diameter), the max flow rate is 15.2k litres/hr. That's plenty of capacity above what i'll be using.

And the cycle process begins.

Tied the prawn to a rock. I recall 'losing' the prawn when i cycled my last tank as it floated away & got wedged in some rocks.

Used more than a bucket of salt for the initial mix :(

Set a little lower salinity for a start. Probably let it rise to 1.025 over the next weeks as water evaporates.

NICE!

Thanks.

 

Started working on stuff like the temperature controller for the chiller. 1st time building this & referred to past SRC posts & google.

The STC-1000 is rated 10A. So it should not be an issue for 1HP compressor. i.e. no relays required.

Cycling still in progress.

In the meantime, finished up a couple of things for the tank

 

Float switch in display tank in the unlikely event the overflow drains are blocked. Float switch will be hooked to the Apex Neptune to cut off the return pump if ncessary.

Kalkwasser stirrer

- Some parts for it 

PA230061.jpg

 

- Decided to build a box with scrap pieces of acrylic instead of using those PVC boxes. This enabled customization to have a clear top to see what's going on inside.

PA230063.jpg

 

- Finished. Pardon the (acrylic) dust

The plan is to stir the kalk a couple of minutes before the ATO is turned on.

Fresh ATO water will then be channeled through the kalk reactor before going to sump

Not to replace CR. 
In my case, the primary objective of the kalk is to push up pH levels.

But i tot it also up cal and maintain your parameters like CR?

Yes, Kalk can be used to maintain Ca/KH. But kalk alone won't be able to keep up. Hence a CR is still needed.

For me, the primary reason is to help push up pH as its running quite low in my tank.
