Top off water to reduce alk?
- Thread starter reefrider

Vinegar won't drop the alkalinity for very long. It binds alkalinity temporarily until bacteria consume the organic acid, but that's typically only hours in a tank. Water changes can lower alkalinity safely, but if you stop dosing all forms of alkalinity, the level should drop on its own fairly rapidly.
Some of the less obvious sources are pH buffers (they all add alkalinity, despite any advertizing) and tap water.

Yes, stopping or reducing the addition of buffers is the obvious answer.
Were you previously adding buffers in your RO/DI water?
Pure fresh water additions won't reduce alkalinity except if you stop adding something else that you were previously adding to that RO/DI.

OK, just stop that for a bit then add less when you are supplementing it, based on alkalinity measurements.
Just so you understand, it may be convenient to use the RO/DI as a vehicle for adding needed supplements, but RO/DI does not "need" any buffering so don't add anything to it unless you know the tank water needs it.

are you tring to buffer the top off water? don't buffer top off water, when it goes into the tank your water will get mixed very quickly and buffer itself, all that buffer is doing is raising your alk.

No, that's not correct. The pH of your top off water has absolutely zero effect on the pH in the tank.
Right, it is not correct. Never add buffers to attain a specific pH, either in the aquarium or in the RO/DI. Only to boost alkalinity.
If you want a pH boost WHEN you need to add alkalinity, use a high pH additive like baked baking soda or limewater.
