LPS-Dominated Dual Tank

[Guest]

Close up the monti!

[hmmm2]

New tank - to accommodate my livestock into a single tank - delivered 
 

 

[hmmm2]

Four days later:

 

I’ve been doing 50-litres water change on the old setup, and use the water removed to fill up the new tank

 

[hmmm2]

Another 7 days later, with one bag of siporax from the old set up, and three bags of new siporax, and three newly purchased fish - kole tang, starcki’s damsel and a Fire goby. So basically the new set up is used as a QT without medication for these new fish:

 

[hmmm2]

Equipment list - everything is from the old set up, except the tank, cabinet, plumbing, sump, some new additional siporax and a second chiller:

1. Brace-less Display tank 5 feet long x 2.5feet wide x 18inches tall, 3 sides crystal clear glass, 15mm thickness 

2. Sump with the following bubble trap design, base image courtesy of gmacreef:

3. Bean animal external overflow, position at centre

4. Lighting: 2x Kessil A360WE Tuna Blue and 1x Red Sea reef Led90 (probably need at least one more to fully cover the tank)

5. Dual return pumps with Dual chillers - 1x Abyzz A100 connected to Hailea HK1000A and 1x Sicce (forgot which model) connected to Arctica 1/5HP

6. Dosing pump: Jebao DP4

7. Skimmer: Deltec 1455

8. DT Wavemakers: 3x Skimz SS6.0 and 1x Jebao CP25

9. Biomedia: Siporax, bought 50L but I think I’ve only put in 30L so far

I’ve a skimz algae reactor too, which I’ll set it up in the near future when the tank is more mature

Wow. Great to have such redundancy

May I know how these work? Both able kick in together same time?

Hailea alone is able to bring the tank’s temp from 26.9 to 25.1 in less than an hour. I set the desired temp for hailea at 26, and, according to arctica temp probe reading, it will kick in at 26.9 and stop at 25.1. I’m not sure how to narrow the range; I read that it’s possible to use an external temp probe to control the older hailea models, but I’m not sure how it’s fine for the Hk series

Arctica alone is able to bring the temp down by 0.1 after running for about 4-5 hours

So hailea is the main chiller while Arctica is the backup, but not running a chiller for an extended period of time is harmful to it 

So the Arctica is set at 26.5-26.9 so that both chillers will kick in almost simultaneously when the tank is at a temp of 26.9

Thanks for explaination. I had wanted to do the same not too long ago but wasn't confident that both chillers will be reading the same temperature. By right they should but depending on the sensitivity of material used for fabrication.

[hmmm2]

Not many people like damsels, myself included

But this Starcki’s damsel is very well-behaves, has tons of personality, and resembles my favourite dwarf angelfish - the resplendent angelfish- which is almost impossible to get now

Another, more zoomed out, shot:

Didn’t do much for the past month as I want to tank to be as stable as possible

 

It is widely believe that keeping Kh as consistent as possible is important, my tank’s Kh now looks something like this and I’m quite pleased with it:

 

pH on the other hand is lower than what I’d like it to be, but having a consistent pH is also important, so I’ll not do anything in the near future to raise it 

And to end it off, a quick picture of one section of the tank:

very nice shallow tank .. And good idea on running two chiller as a backup, do you see any signification increase in the electrical usage ?

Thanks!

I’ve been running it this way since the beginning so I’m unable to compared it with running only one chiller
