125 gallon about 130 with filters.. Tank long established. PH 7 to 7.6 usually closer to 7.6.. Ammonia 0 nitrite 0... Nitrate high was "I believe" over 100. Did a 50% sat 30%. Looked like it was reading 40 or 80.. Today it looked the same just did another 30% water change.. So instead of these monsters every few days will a quick 10% do justice on reducing this. Tank as of now is well under populated with 3 red hooks 2 baby Oscars and a 6 inch cat. Both filters cleaned out within past 3 weekends as well. And no dumb questions I didn't use soap or rinse with tap water.. I was doing a 30% change weekly with no luck lowering the nitrate any other ideas? It's pretty annoying considering the fish are all still small.. I could understand if I had a tank of adults then I'm over my max and it would make sense.

What are the tap water nitrate readings?

Small water changes are not enough when fish are producing nitrates at the same time, especially when the nitrate reading was already in the 80ppm range. When you are doing a 30% water change at 80ppm, you are only reducing nitrates down to 46 ppm, and that's without nitrate in your tap water.

You need to change enough water so it is only an inch above the largest fish.

Plus can someone explain what the difference is between 40.and 80 on the api test cause to me they are identical.. That's why I don't know if it's 40 or 80

You need to strive for plain orange, with the best outcome being between 5ppm and 10ppm, considering you already have 5ppm out of the tap water. Don't worry about the difference between 40ppm and 80ppm as that is too high already.

Sometimes tough, everyone sees shades differently. Regardless, you need to drop the nitrate level under 20 and strive to keep it there. Larger volume and more frequent water changes, until you get a handle on what it takes to keep nitrate at less harmful levels.


I may not be the Boss, but I'm ALWAYS right!

getting high nitrates means your filter is is working very well...
have you tried to do large water change without touching the filter?
say 80% new water filling the tank gradually
