I have decided to dose ascorbic acid for two reasons: first it is a source of organic carbon, useful for denitrification and consequently for the luxury uptake of the phosphates by the bacteria; second, ascorbic acid seem to be able to protect the coral tissue from heat stress, reducing the expulsion of the zooxantellae.
The dose of 1 gram derive from the lecture of an article in which the reduction of the zooxantellae expulsion was obtained dosing 1 mg/liter of ascorbic acid.
This dose is enough for denitrification too, in one week my nitrates drop from 10 to 0, phosphates 0....and very clear water.

Luca with No live rock and few cm of substrate, where do you think you have anoxic conditions in your system ,for proliferating denitrify bacteria ? The only reason you use ascorbic acid instead of vodka or vinegar or a combination of them, is your high temperatures? What pump do you use and how many Lt/h?
In biology we must think small.
It is not correct to consider the sand bed the only place in which may develop anoxic condition.
This may happen in the center of bacterial flakes (ranging from 100 micron to 2-3 mm in diameter) or in the deep layers of bacterial films lining on rocks or others objects.
To support this fact, there is an article in which was noted that a DSB of 2.5 cm deep was enough for biological reactions like denitrification.
The answer to the second question is yes, I use ascorbic acid in spite of sugar or vodka only because the high temperatures.
Third, my pump is an infustrial one, made in stainless steel AISI 316 with an asyncronous triphase motor of 350 watt and35000 liters per hour.

Yes Matt, probably a dc pump develop less heat, but the biggest problem is the thickness of the walls, 5 cm of acrylic.
Do you know the passive houses? Well, I have a passive aquarium :fun2:.
My long term plan is to replace the heater with a heat exchanger connected to a condensing unit and controlled by the temperature sensor that I have.
One pic of the tank and one of the green star polyp introduced 5 days ago.
