a little weird.

I have lost my last platy. I just have my silver tipped shark, algae eater, and molly.

I did a water change on my 75 gal tank, like you guys had advised, (I used to just vacuum the rocks until they looked clean, only removing about 10 gal each time.) This time I removed about 20 gal and put 25 back in. I tested it before and after the change and here is what I got.


Before water change:
Nitrate...40
Nitrite...0
Hardness...1000
Alkalinity... 300
Ph...8.5

After the water change: (about 10 min after)
Nitrate...0
Nitrite...0
Hardness...300
Alkalinity...300
Ph...8.0



What does this tell you? I only put a de-chlorinator in it, I was not able to get a good conditioner yet. I will for next time.

I will still be looking into finding a new home for the shark, and i will be adding any new fish until probably after Oct 1st due to our house has gone into foreclosure and we have to move!

Thanks!

Sorry to hear about your loss. A 20% water change should not have made that kind of difference in water chemistry. Do you have ammonia readings? Ammonia is just as important to track as the others, sometimes more important because it is the first stage of waste breakdown.

Based on those readings I would have to say this tank was over cleaned... but to go from 40 to 0 in nitrates with just a 20% change does not sound right.

My first question would have to be what kind of test kits are you using?
