Concerned with readings low PH and High alk.

[Sunstar]

I need advice on this.

 

I use RODI water. TDS last time I made water was reading 0, which was last week, the day before the 08 test. I am going to drop my sal to 1.024. But for some reason my alk is going up and I am not sure how to get my PH up. I am increasing my mag, which is good. It's getting there. But the alk and PH is my concern. let me know your thoughts. the PH test was recently obtained hence the lack of info on previous tests. I had to get a new package.

 

 

I forgot to mark it in but the po4 is also 0

More than likely it's an excess amount of dissolved CO2 as all your other parameters are in check. Take a cup of water and set it outside for a few hours. If the pH increases you will know it's due to excess CO2

What do I do in cases of CO2?

It's most likely the heating system for your home which is not something you can fix. The best way to deal with the issue is to have an airline running outside connected to a protein skimmer or airstone. During the warmer months you can just open a window.

I live in a high rise. our heating is hot water. I generally leave a window open (all seasons) Location of tank is not conducive to running airlines without clothes lining people.

 

how long should i leave the water outside, its a bit nippy

 

 

read 8.0 outside.

If the pH has increased then it's safe to say it's due to excess CO2 in your home. If your tank has adequate surface agitation and adequate air circulation either there is some source in your house producing CO2 or your tanks livestock is producing CO2 faster than the gas exchange at the waters surface.
