:thinking: I just read in a book that excessive amounts of ALAGE cause a excessive organic acids in the aquarium, which in turn will lower ALK.
That is something I was not aware of!!! I have a good amount of Macroalage in my tank like Caulerpa and a frilly red alage that is quite attractive. I have no nusience alage like hair or even anything green like that.
So the reason I keep it there is to lower my nutient level and nitrate level...then I will crop it out every water change. So I am now thinking that I always buff my ALK to keep it around 10-12 DKH....could this be the reason for the unstability of my ALK?????

Photosynthesis by the algea ( durning lighting period ) will reduce the CO2 levels and raise Oxygen levels. This can effect the pH but Im not sure about Alk.
This is why some tanks have a pH swing from night and day and some people use a reverse lighting period on their fuges.

I was quoting Wayne Shang from the book "The Captive marine Aquarium" This guy has been doing Salt water tanks for 20 years. He now has a 700gl Acro tank that is unbelievable. Acros that are 2-3 feet wide....he also says that in a study at a university they proved that the highest coral growth is at an DKH level of 12. Just by looking at this guys tank and it shows the growth rate of some of the corals, I will listen to just about anything he says.
Yea so algae lowers ALK. WOW
