nitrate -80 ppm
filter--Fluval 405 with good carbon,carb/ammonia bags.Filter is cleaned/carbon replaced every 30 days.
Occupants--2 large Oscars
Just wondering what would be a good way to reduce the ppm of nitrate? I have done 25% water changes/gravel vac every other week.I then ad fresh water,then treat the water with conditioner that eliminates nitrite,nitrate,chlorine, chloramines . My tank is growing algae on the back glass and plants,and the nitrate level has me a little worried,but it does not seem to be getting worse than this around 80 ppm.
Should i use a tap water filter when replacing fresh water?.I have read that most tap water supplies have nitrate.
All of my testers (ph,nitrite,nitrate) are API 5 ml. tube&droppers
These pictures are of the back of my tank ONLY 1 week after cleaning the glass.
I log onto this forum 3 times a day,If there is any other info needed.
I would increase the water changes to every week at least 50% doing a good gravel vac each time. Oscars are messy fish.
Have you tried testing your tap water for nitrates?
No,I have not.I will do that.
Ok,I tested the tap water,and it shows 10 ppm of nitrates.
