My Tank Thread
I have watched this video before. He states to tell the controller to dose two times the amount of evaporation in 24-hrs but only have it dose 12-hrs at night ?
I am my controller - I would imagine it would be harder to acclimate corals to NSW parameters after the corals get used to higher PH and ALK ?
Randy said : "A drop from pH 8.5 to pH 8.2 is about 50% drop in carbonate."
Probably happens !
“So let it be written, so let it be done”
I did not watch the video, but that means dosing 2x the evaporation, overall, every day. How exactly does he remove that much water each day and replace the salinity? Sounds tricky to me.
In a 100 gallon tank with 2% daily evaporation, that means dosing 4 gallons of water to the tank, reaching 102 gallons at the end of 24 h.
Removing 2 gallons of tank water takes the water back to its starting level, but the salinity is now down by 2%. Presumably that can only be added back by adding salt water (not solid salt mix), which increases the water volume again.
i don't see how this works out without adding solid salt mix directly (or using a lot of two/three part alk and calcium additives that boost salinity).
