alkalinity

[goldy222]

Question about alkalinity. If an aquarium has low alkalinity, is it true that phosphates will rise quickly from fish waste and uneaten food, which in turn will cause algae problems? My understanding is that proper alkalinity levels will help the water absorb waste, so phosphates are kept to a minimum resulting in less algae. Is this Correct? I'm new to salt water and trying to understand how alkalinity levels are important to unwanted algea in the aquarium.

Alkalinity is the ability to stabalize PH. A low alkalinity will allow the water to have big PH swings. It is sort of like buffering capacity of the water. It also plays an important role in your calcium levels and the ability of your corals to use the calcium. Do a search on alkalinity and you will find a wealth of info.

Low pH can lead to more favorable conditions for nuisance algae to grow.
