Lasses Dream Build

[Lasse]

Lasse,
I love the way you went about building this system, you had a great plan to start out and just went for it with a tweak here and there. Very well done, your knowledge and experience have served you well and I hope I can learn a from you. Thanks

Thank you

Sincerely Lasse

I have loved watching this evolve, hat's off to you. :)

Some newcomers and some old favourites



I have been unlucky with introduction of Synchiropus moyeri in the past. I´ll give them a new try

One new clam

I like the pyjamas cardinal in large numbers – 9 more has moved in. Total 16 of them

The sponges grow well

Some old favourites

​

I have one new “dream” fish but I´m not sure it will make it. It was very stressed after the long flight from the Philippines. We will see in the future

In another thread here at R2R I was stated that my secret tool was two sentences – Keep your hands dry and if it not broken – do not fix it.

I wish I had read it yesterday. 04:30 I got an alarm of power shout down at the fish farm I work at the moment. During the night – I had got 5 false alarms from one of the production lines. I was in a great shape in other words….. After fixing the power break and restart everything – I start to figure out what have caused the false alarms. It took till 14:00 before it was solved and I got home – just to notice that my illumination of my reef tank did not work. The lamp had lost its firmware….. probably due to the same power shout down.

Need a reserve – not easy to found so I contact the vendor and with some E-mail conversation (and some proper Swedish language) I could restore it again and got it to work the way it should. Back with the drivers and stuff in the sump cabinet.

My intention when I build the aquarium was a clean cabinet with all cables and tubes in an excellent way – Dream on as my wife use to say – after a year the cabinet looks like a snake pit of cables and hoses. And dam – I can´t reach that cable – I have to push harder. What happens after this moment – I prefer to forget. My wife was not at home – lucky her. The only thing was to take out all electrical devices, all pumps, all – you name it. The floor in the Livingroom looks like London during the Blitz – but lucky for me – before the fire brigade show up – no water at the floor – only thing, thing, cables, hoses and things again.

With all equipment on the floor – the light back in place – time to put all other things back again. I had plan to shift my computer (from PL 3.0 to PL 4) so now was time to do it – Decision taken around 18:00 in the evening – all accomplished around 00:30.



My plan for the future is to Keep my hands dry and do not even fix things when they are broken…….



In my new computer set up I decided to have a pH electrode in water space under my DSB. I have already a redox electrode there but I want also to follow the pH. When I open up my refugium (over the DSB) I took the chance to harvest a bit Chaeto (see picture) – it grows good! This is the harvest for 10 days!

I also try to found a wrasse that have sneak down in the 28 liters refugium. But the refugium has a 25 cm DSB as gravel - not even food make him/her coming up. It’s still in the refugium.

First measurement of the pH below the DSB show a little surprising figure. I will monitoring it for a couple of weeks and make a new calibration in 10 days.

Replacing my PH probe tomorrow and I will also be pull all the wire apart:oops:

Good Luck and may the force be with you :)

Love this thread. What light do you use when taking pics?

Thank you

I use my normal aquarium light (Pacific Sun Metis Hyperion SMT 3* 145 W)

The secret behind the fact that I do not get any blue colour cast is that my camera has a wonderful property. You can adapt the white balance in a simple way. Just find a true white part in the aquarium (The sand sometimes but I can also put a white plastic piece in the aquarium), Point the camera towards the white part and push a button – the camera will find the right white balance by itself. He camera is not a fancy one but one of the best compact cameras ever – Olympus Tough TG-3 – My camera is a couple of years old and I think that its Olympus Tough TG-4 today. I can also film with it and have it in the water. (Has not done that yet)

Great! Are you pleased with light coverage? What are tank dimensions?

Lasse they are up to TG-5 now. Time marches on. [emoji3][emoji106]

The DT is 120 cm * 50 cm * 50 cm

Yes - I am satisfied with the ramp. I like the fact that it has no phosphorus coated white LEDs. This means that you are able to see some of the fluorescence even then you think you have a white light. You do not need to run blue only I order to see them. If you mix blue, red and green – for your brain it looks like white light but there is not much of the wavelengths between 500 and 600 nm in the light – the lumen window – that will block your brain for seeing the weak fluorescence sources from the corals

Just a thank you for a great thread. Been following for a bit and looking forward to following the progress.

Great tank.

pH over 8,4 under the DSB? Thats interesting! Any thoughts on that?

How do you plan on dosing the CO2 under the sand bed? Bubbles feels like they would just go right up through the bed and up to the surface.

I will be back at work tomorrow after 3 weeks holiday, time to see how our RDSB works :)

It´s a little bit lower now - 8.25 - but it is interesting. I´m not sure that it’s a real reading because there is probably a low circulation area around the probe.

I have - since the reading of 8.4 - rise the amount of water through the bed. This can explain a lower pH for the moment

I also calibrate my redox probe and its shows negative redox.

Low flow, negative redox and higher pH -> theoretical it means that it could be a denitrification area – but I do not have enough of fact to be totally sure of it.

Saturday evening I had around 4 ppm NO3 – I´ll check the figure later on and see if I can have more facts that indicate denitrification. At my work – I have seen higher pH in anaerobic environments compared with the same systems aerobic areas.

For your others – RDSB – means Reverse Deep Sand Bed and David has done a genius DIY construction of this concept that he try to evaluate for the moment.

In spite of my standpoint in another thread (mankind’s contribute to the CO2 in the atmosphere) I just order one of these :) Human beings is not rational :)

Got my latest results from Triton lab today. All was fine without one parameter – the Si concentration – it was – I hope you are sitting steady - 7035 µg/l I know the reason but it’s difficult to fix it without taking up my whole DSB. I did the mistake to place 2 litre of SIPORAX in the bottom. It seems like it release Si during anaerobic conditions (David at Sjöfartsmuseet Akvariet – a public aquarium in Gothenburg – has seen the same happens there but not so high concentrations)

Any ideas of something that can take away most of this? – It start to rise 14.10.17 from 281 µg/! -> 1071 µg/l10.1.17 -> 1114 µg/l 6.5.17 to 7035 µg/l 30.7.17. I had risen the flow (reversed ) through the DSB just before I took the sample. I do not know how long time I have had this high figures. But the standpoint that high Si values cause blooms of diatoms by itself will be ruled out – at least in my aquaria. Anyone – any thoughts?

7035 µg/l -> 7035 ppb -> 7,035 ppm

Hi, I have been struggling with the launch of my reef for a long time, I could not understand why, I did not have TRITON measurements, but I always saw an imbalance of nitrate phosphate in my system (NO3 0) 4 liters of siporax. The year was lost - everything was fine, it could be a coincidence .....
