My tank is low on alkalinity resulting in massive GHA outbreaks. Any recommendations on how to dose it?

YesUsing RODI?
Nitrite 0 Nitrate 0 Phosphate a little highI've never heard of low alk causing a GHA outbreak. What are your nitrate and phosphate levels?
I am using red sea test kits I will test my water again to get new results.As a few others have eluded to, it's not likely that low alkalinity has contributed to the GHA outbreak. Can you post your parameters here? What test kits are you using? At a mininum, please try to include the following parameters so folks can help you out:
Alk - Helps maintain pH.
Magnesium - Helps maintain alk without precipitation
Phosphate - Contributes to algae growth
Nitrate - Contributes to algae grown
I was told that low Alk and low magnesium can cause it
Tell me how it works.You can use baking soda. Everything you need to know about that is on the BRS Aquarium Calculator.
Thanks and what does the baking soda do? Dose it help with phosphates or alkalinity?
Thanks I will start this method and update this thread in a moth or week to tell you how it went.Alkalinity is primarily bicarbonate and carbonate.
Sodium bicarbonate (baking soda) adds the bicarbonate of alkalinity.
Maybe phosphates? I cut back on feeding and added a skimmer a few months ago it has been helping.I’ve had low alkalinity indirectly cause gha problems early in my reefkeeping career by letting it slip and triggering my coraline algae to die off, which was then colonized by gha within a few weeks. I doubt that is the cause of this fellows problems though.
