Checked the water with the API fresh water test kit after being out of town for 4 days- ammonia .5, nitrites were 2, nitrates were 60, pH 7.6. Yikes! I did a 50% water change yesterday(did the 5x amount of PRIME to detoxify nitrITE), did a 70% water change today. Ammonia .25, nitrites 1, nitrates 40. I have the water setting up for a 70% change tomorrow and was planning on 50%-70% water changes daily until the levels get to where they are supposed to be.
Now, the fish seems to be OK and I read not to do a 100% water change when nitrITES are too high. Hopefully that's correct info and everything will be OK in a few water changes. PRIME is supposed to detoxify high nitrITE for 48 hours and the test kit doesn't distinguish between toxic and detoxified nitrITE.
What I found out was my fish was greatly overfed in while I was away...even though I left instructions.
Now for my question. When comparing the colors to the chart do I hold the vial slightly away from the white card(which makes it a lighter shade+lower reading) or against the white card(which makes it a darker shade=higher reading)?
