Hello:These are all the system i have running now.
The total consumption of all tanks during daytime (15:30h) is about 4700watt
Average light period= 13hours
(2300+1050+1080+120+120)
The total water volume is ~ 6100 liters
I estimate all the tanks uses ~65KWh per day.
Atm i am into full led, section1 is with GHL mitras LX7206 and section2-3 are my own design.Awesome build! Stunning. Question - what lights are you using?
I love your display tanks, they’re absolutely gorgeous. I am using your DSR method, and for my 350 liter tank with just six small LPS corals and some number of life stock, I noticed that my Mg level is too low at Mg = 1032 ppm. Furthermore, I noticed that the salinity had dropped slowly over the course of five months from 1.024 SG to 1.022 SG (probably due to the skimmer, measurements taken and filter replacements, all removing salt water from the tank). I therefore decided to perform a 34% water change using Red Sea Coral Pro Salt (Mg = 1350 ppm), in an effort to increase the salinity and the Mg-level. I know that using your DSR method does not require a water change, however, I was not sure how to solve the problem. I am dosing:Enjoying a bunch of beautifull acropora's
Thanks m8, i enjoy my tank everyday and always looking to improve.I love your display tanks, they’re absolutely gorgeous.

I know that using your DSR method does not require a water change, however, I was not sure how to solve the problem. I am dosing:
DSR EZ-Buffer = 13.0 ml
DSR EZ-Trace = 1.3 ml
DSR EZ Calcium = 2.6 ml
DSR EZ-Carbon = 3.0 ml
Before the water change, the nutrient levels were:
NO3 = 4.59 ppm
PO4 = 0.032 ppm
The trace element levels were:
Ca = 413 ppm
Mg = 1032 ppm
Alkalinity = 9.80 dKH
Salinity = 1.022 SG
The day after the water change the parameters were as follows.
The nutrient levels:
NO3 = 3.27 ppm
PO4 = 0.036 ppm
The trace element levels:
Ca = 424 ppm
Mg = 1120 ppm
Alkalinity = 10.62 dKH
Salinity = 1.0240 SG
Additionally I am running a power filter in the DT, a skimmer and an 18Watt UV filter in the sump, and chaeto macroalgae in the refugium. I do not have activated carbon or pellets.
Yesterday I started dosing 35 ml GroTech Magnesium Pro Solution daily in an effort to raise the Mg level (35 ml should raise the Mg-level by 5 ppm).
I have to say that my corals are doing well, both before and after the water change, except that a small torch died just before the water change.
Could you please perhaps point me in the right direction as to how I should proceed to get the Mg-level back at where it should be?
On your website you mention that the ideal ratios for Buffer:Ca:Mg are 5:1:0.5. Are these the ratios I should stick to at this stage?
Many thanks in advance

Very Nice! What is the hanging set up you have for your homemade LED's? I thought I saw somewhere in the thread that the suspension frame is motorized. Do you have a schematic/diagram for that?
Thanks m8, i enjoy my tank everyday and always looking to improve.
Low magnesium and salinity are probably being caused by wet skimming at low alk consumption. There is No need to do waterchanges, this can very easily be adjusted with fullDSR products. Kh,Ca, Mg,K, etc... First adjust the macro elements with the corresponding products, than adjust the salinity with pure NaCl. Use the compact calculator to do so. Http://dsrreefing.com/compactcalc/
You need 673gram of DSR Mg plus to raise Mg. spread it out in 5 days.
If Mg keep on dropping in time you might want to raise the EZtrace dosing to keep up the consumption.
The dosing ratio is a recommendation, you can tweak each liquid to compensate for real consumption.
Use a calibrated refractometer to adjust salinity between 33-35ppt. They represent the right units (ppt) to work with. SG is temperature dependant and often mis/inaccurate implemented.
Also use the EZcalculator to determine dosings and consumption.
Http://dsrreefing.com/ezcalc20/
According to the EZcalculator you need to stop dosing EZbuffer for about 1 week to let it drop back to 9dkh.
You also can raise you Ca by dosing an additional 32ml EZcalcium. (Or use fullDSR components)
Determine you real consumption by filling in the interval (days) between measurements into the EZcalculator
Make sure you do corrections and the adjustments to dosings as well
Thanks so much for your response, that's much appreciated! I've bought DSR Mg+ and I will add it in small volumes spread out over 5 days to the tank.
Mg is within the goldilocks zone again, and is creeping up to 1223 ppm.
There is some green hair algae (GHA) growth on the rocks and glass of the tank, near the light. Since Feb 2021 I never completely managed to get rid of GHA, i.e. the rocks were always covered with a thin layer of it. I therefore brushed GHA off with a brush every two or three months or so.
I did use a fluconazole treatment over the course of 14 days, twice already. The treatment did reduce the GHA infestation significantly. However, with the next PO4 swing, GHA creeped slowly back in again.
My question is basically, how do I use the DSR calculator (EZcalc20) to ascertain the dosing volume of EZ-Carbon?
I ultimately want to get the nutrient levels stable.
I should probably increase my Carbon dosing over the course of 15 days until the NO3 and PO4 levels are within check. Subsequently I have to reduce Carbon dosing, but how do I know at what dosing level to stop reducing Carbon dosing?
I sometimes add 1.4 ml of EZ-2xNO3, to get NO3 up a bit in order to reduce PO4.
Currently I measure:
PO4 = 0.075 ppm
NO3 = 4.5 ppm
Many thanks in advance
