I've kept all kinds of fish and its more than one fish tank. 55 75 125. I have fish that are from 6-10 years old. And Iv probably gone longer than half a year.
False. What reason would I have to make this upfolks will claim what they will, just hate that some folks take it for truth when it most certainly is not.
Personally I try to keep my nitrates as low as possible.
Like pops, I also use an API freshwater "master" kit, it's cheap (considering the price of some kits) and fairly accurate as well.
I test my water before and after each change. If the test after the change says the nitrate is above 10ppm, I'll do another large change the next day to "reset" it to zero. This normally happens every six weeks or so on my big tank with my current WC schedule and a little less frequently on the smaller ones as they're not stocked as heavily.
Good luck with your oscar.![]()
I give it an hour or so after changing before I test, I realize that testing directly after is pointless. My tanks all have approx 10x hourly turnover (slightly more on the big tank) so an hour or so (sometimes longer, I'm rather absent minded at times) is plenty of time for it to mix.You do understand that right after adding water is not a good time to test. You have to let the new and old water mix well to get a true reading. Trying waiting several hours after a water change.
Also if you have 10ppm nitrates and do a big water change, by this I assume 50% or in and around there. You are still going to be left with 4-5ppm.nitrates not zero. The only way to zero out would be to start from scratch.
