As some of you lovely people may know, I recently did a 10 gallon water change (25%) using Deer Park Spring water. Now, I don't know if these two events are related, but when I came home yesterday, the tank was completely covered in brown yukky stuff. What a mess!! My protien skimmer is working overtime! Now, I don't know if it was the Deer Park water that caused this brown algae to form overnight, but just to be safe, I decided that spring water might not be the right way to go. (That, and the fact that many here said it was not a good idea for a reef tank)
So, I decided to go back to the tap water DI
filter I bought from the LFS
when I started my aquarium. It is only 3 weeks old, and has only processed about 50 gallons of water total. The directions say to set the flow rate so that it will fill 1 cup in about 25 to 30 seconds. I did that.
I filled a bucket (clean) with one gallon of this filtered DI
water, and then added salt, and brought it to 1.022 SG
and 78 degrees F.
Then I did all my tests on this water - I wanted to make sure it was usable as replacement water. The results were SHOCKING!!
pH = 8.2
Amonia = 2.0
Nitrites = 0
Nitrates = 0
Calcium = 400mg/L
Amonia of 2.0! I don't understand why it would be so high from filtered water. I did mix the salt in with the same metal measuring cup I used to measure the salt. Could stiring the mixture with a metal cup cause this reading?? Should I have run the tests on a larger batch (i.e. 5 gallons)??
are wicked high. They are also high in the tank.
How do I lower KH
? These hardness numbers are pretty confusing to me.
I'm at the end of my rope. I can't use water from the tap. I can't use spring water. And it looks like I can't use water from this DI
filter, either. This can't be that hard. I find it hard to believe that every saltwater aquarium owner in the world has an RO
filter installed in their home. It isn't supposed to be this hard. Anybody have suggestions? What am I doing wrong?
Thanks in advance for your patience!
