Could you offer me some advice My tank is almost 2 months old. I have quite a decent stock level of fish my ammonia ams nitrites are zero however i have had a few fish die recently, mostly cardinal tetras.
When I test my nitrates with tetra kit it shows nitrates close to 100mg/l. The tetra nitrate test kit comes with a vial and a silvery powder as well as 3 different bottles labelled one two and three. When I test without the silver powder added nitrates read 12.5mg/l. I tested without the silver powder as when I lived overseas the tetra test kit didn't have the powder included only the three bottles. But when I add the silver powder to the test vial nitrates show 100mg/l.i added alot more plants this week and a floating plant that was told removes nitrates. I also rinsed my filter media in tank water so not sure what else to do. I dose tnc complete. As I have a decent stock level should I just use tnc light instead as my tap water already has nitrate readings around 18.5mg/l.
I have bought seachem pristine and will be adding this to the tank today.
Can cardinals live in relatively hard water.or what can I do to soften the water is ithis reqrequi to keep cardinals. If an RO water filter is needed do you know of any decent brands and prices.
