@Gaël Thank you - I think I have figured it out now. It seems like it is a *.cvs file like this that is the demand for english language. I use 24 hours time format

Take some time to do it in Excell and convert it in notepad. The basic data I have got from this website You can chose month further down at the website and I use the daily min and max and put them at 04:00 and 16:00. Something excellent I have notice is that it calculate the actual nominal value along a line - not as switch points Today - my highest temperature should be 29,5 degree C - and the lowest 27,7 degree C. I use a offset of minus 3 degree C (because I do not dare to run my aquarium at nearly 30 degree C)

In this moment - 4 hours before this days highest temperature - my dynamic value shows 25.9 - based on a list temperature of 28.9.

I do not run it sharp yet - I run it on my spare and test P4

I use Edge browser and it will translate to English. I'm sure other browsers have that functionality as well. One will just have the pictures still in German. Attached is a PDF of the translation.

Today I start an experiment with temperature variation between day and night. I want to know if it - as an example - affect my salinity measurements or not- I plan to have this type of variations

This is the uploaded CSV file

I have a second virtual temp probe that manage my chilling fan. For the moment - I run it on the same DNV channel - maybe I would need a offset for this controller.

My test with dynamic nominal value (dynamic serpoint) based on a file works very well - below my temperature during the last 39 hours shows how I succeed to vary the temperature with 2 degree C with help of my file. Blue bars is my heater working - 1ml = 1 min (I use a virtual pump with virtual calibration 1ml/min in order to sample my heaters working time). My heater is 200 W - total on time during these 39 hours is 920.5 minutes = 15.3 hours -> 3.06 kWH/39 hours -> 1.8 kWH/24 hours. Before this experiment - I used around 1.1 kWH - it will be more expensive.

I do not know how much this swing in daily temperature affect the biological life of my aquarium - but look at my KH (set point 7.6 and adaptive control) before and after! This need to be checked up - I´ll plan to run this temperature schedule for at least 1 week and see was happens.

It seems that my calcification rate (calculated on a 24 hours cycle) has been stabilized. My dosing of the alkalinity part of Triton Core 7 is different between night and day and is adapted after the last reading of KH - see below

Exciting isn't it?

I got my new toy yesterday - a Hanna Marine Master Bluetooth. i have done some initial tests and some of the results was there I suspected - some did not did not match what I expected from other measurements. But it was new routines for me and I know that it takes at least 15 - 20 tests before you master a method completely,

The PO4 ULR method give me some very interesting readings (or in worst case erratic readings) that may confirm some findings I did many years ago according PO4:s daily swing. However - I need a longer serie before I can confirm this.

The marine total ammonia test was interesting. I am going to test that for a while in order to confirm a normal concentration in my tank. The first test said 0,13 mg/L total ammonia (NH3 + NH4) which correspond to a NH3 concentration of 0.0087 ppm NH3 with my present salinity, pH and temperature (This calculator) from hamzasreef.com.

This instrument feels much more like a quality thing (compared with the checkers) and if I forgot to read the result (which happens) - I have the result in my phone. Its also possible to do multiple readings of the same samples in order to see variation in readings without make a zero between the readings.

According to my KH and the daily swings of temperature - still surprised of the result. I changed the setpoint to 8.1. For sure - this looks interesting because I have no answers if this pattern will continue or not and do not know why KH get stabil when I have a daily swing of 2 degrees C

My light intensity and resulting pH 28/2. Note that light peak at around 16 - Consumption/production+diffusion of CO2 is equalled out 1.5 hours later and are equal for 2.5 hours more

A couple of days ago - I got a new toy -. A Hanna Marin Master 97115. Ir was not cheap but as my wife always say - the difference between the toys for the boy and the man its the price.

Till now - I´m rather impressed. For the first time I feel rather comfortable with measuring low concentrations of phosphate with hobby gears ( However, it feels more like a semi professional piece of equipment than a pure hobby thing)

Manny years ago - I did (with a professional equipment) a investigation in my present aquarium according PO4 variations on a daily base. I found there that there was a clear difference between morning (before light on) and evening (before light off). I have tried to repeat findings with Hanna checker - but I never get more than indications and not consistent results that back up the findings before. I have not access to that equipment I use 10 years ago today. But the Hanna Marine Master ULR PO4 seems to manage this. I have done some measurements and it seems promising - soon we maybe can start another huge discussion about PO4 measurements and what they tell us. I´ll think that this graph can be surprising - but really not for me

The error bars is the methods accuracy (±0.02 mg/L)

HMM will also introduce a new method (at least for me) that may can help us to understand total ammonia in our reef. The accuracy of this method is 0.05 mg/L and the question is if it is enough to make it useful for detecting daily swing. There is very few total ammonia measurements done on mature aquarium reefs so no one really knows "natural concentrations". At least can my measurements give us a floor because it seems to be stable results - indicating lower in the morning and higher in the evening - but it is variation within the margins of error for the moment

The Marine Master can detect pH, Alkalinity, magnesium, calcium, High NO3, Low NO3, ULR NO2, Low total Ammonia (NH3+NH4) and ULR PO4.

PH reading have an accuracy of ± 0.2 in pH and it is not good enough if you - as I have - an pH meter.

I have test calcium and magnesium twice and Hannas result is not the same as I get from my Salifert test (around 488 mg/L for HMM compared with 430 for salifert. However - HMM:s accuracy is ± 6% of read value. I have to learn it better and later on - compare with an ICP-MS test The test is tricky - you only use 0.1 ml sample and its complicated. I´have to train and see what's coming up later

I get rather high Mg readings too - but there I do not really knows where I should expect to be. Its also a tricky test. Have a learning curve. My reading now is 1420 and last ICP said 1367. If I still have around 1360 on ICP - the HMM:s reading is inside the accuracy (±5 % of read value)

High NO3, ULR NO2 and alkalinity works as good as corresponding checkers. Low NO3 - haven´t test. Will do that further on. That test is not included in the package.

On the whole, I am satisfied with the purchase of the HI97115. The Bluetooth connection and the Hanna lab app are good accessories together with Hanna cloud.

After buying the Hanna Marine Master - hI have done total ammonia tests at 10:00 and 19:00 o´clock in my nearly 8 years old aquarium. I do not know the quality of Hanna marine ammonia checker but the Marine Master variant seems very steady and consistent. With help of temperature, pH, salinity and reading of total ammonia (NH3-NH4) its easy to calculate free toxic NH3 with help of this calculator

Here is the graph of my 3,5 days measurement

Salinity during this period have been 34.5 psu, temp at 10:00 - 25.6 C; 19:00 - 26,3 C. Mean pH value at 10:00 - 7.89 and at 19:00 - 8.15 which with help of the calculator will give a concentration of toxic NH3 as the graph below.

NOTE - 19:00 2/3 and 10:00 3/3 is the same NH3-NH4 concentration. But - because both temperature and pH is higher 19:00 2/3 compared with 10:00 the day after - toxic NH3 is nearly double the value in the evening 2/3 compared with morning 3/3. still not any alarming values.

By the way - Phosphate have the same pattern today

I will just try to anchor this small coral the large Euphyllia skeleton - poff - the whole skeleton just fell apart. The skeleton arms was 10 - 20 cm long - just growing out from the backside. There was nothing below them. Just water. It was looking looking like this.

I know that this moment should come sooner or later - but today.........

And I was alone at home

Get a bucket - take out little water and up with the whole euphyllia colony. Took away all dead skeleton without polyps (by the way 1.6 kg) and replace it - and a total new aquarium rose like the phoenix bird from the ashes (the ruins of my old aquarium)

​

Long awaited newcomer

​

Rather new blenny

Older one

Still here

Nearly eight years ago - the tank look like this

If you compare with this

Everything you do not see in the first picture is formed inside my aquarium - during time - a complete new reef structure has been formed

Sincerely Lasse

 

[Lasse]

Keep your hands dry or protect them when handling euphyllia!!!!!

​

However the result was good - maybe worth a tube of cortisone

​

This guy have been here for 7 years now

This only for around 5 years

Lasse, are you still using the Olympus TG6 and do you add any lens or filters. I saw your recommendation in the Photography thread as I am looking to buy my first camera to take photos of my tank and also grandchildren.

This is a great post to show how patient you need to be in this hobby.

Yes - still use it - no lenses and no filter. You have an inbuild adapter for white balance before shooting. Its a great camera. Both for pictures and videos - IMO

Thank you, appreciate the advice. I need simplicity but want to catch the wonderful coral colors!

Hopefully I can find it on sale.

Btw, your Tank is beautiful- and the videos are great!

Last friday I discover that my day pH was more than 0.1 higher than normal - my day peak use to be between 8.22 and 8.27 - friday it peaks ar 8.38. I did not have any direct explanation for this - the house had been as closed as before - still low temperatures outside.

Saturday morning I saw that my pH below my DSB and my redox below the same DSB was also low. This normally indicate now flow through the DSB and so it was . The pump had stopped. and I can see exactly when - around 14:00 on friday.

Can the fact that there was no reversed flow through my DSB be the reason for the high pH during friday afternoon? My answer is - yes. I dose ethanol into the plenum below the DSB and it among other things, fertilizes heterotrophic bacteria under and in the sand bed. When we normally speak about dosing organic carbon - we seldom speak about where the organic carbon end up. The answer is that around 80 % end up as CO2 - especially if the environment is aerobic. The high pH during friday afternoon could therefore be a function of no flow and hence - no CO2 rich water reach the sump and DT.

I change the pump around 12:00 saturday. If my assumption has validity then the pH should drop when the circulation starts again and carbon dioxide rich water comes to the sump and DT - and it did - with 0.07 units - from 8-07 to 8

At least in my aquarium - the relative low pH during time is mostly a function of internal produced CO2 - not the CO2 content in the air - even if it affect it too
