Alk dropped due to DOS issue

[djbetterly]

So I had been measuring my alk regularly, and I thought it was being used up, so I kept increasing the elements. Finally when it kept dropping I realized it was an issue with pump #2 of my DOS. Apparently serials under 5000 have faulty roller assemblies and the liquid would siphon back into the jugs.

SO, what is the safest way to raise my alk? Can I do it all at once or should it I do it slowly over 24hrs?

Also, if you own a DOS and your serial is under 5000 go here to get a replacement set. They are free.

How fast to raise it depends on how much it needs to be raised (IMO).

What is it now and how high do you want it?

Well I brought it up from 6 to 8 over a 36hr period. Wasn't sure so I did it slowly.

Everything seems OK now?

 

[djbetterly]

Yeah, nothing seemed too stressed even when it was low.

Sounds good.

Happy Reefing.
