Neos and Nitrates

627 Views 3 Replies 3 Participants Last post by  fiddleshe
How high of nitrates can neos tolerate? I ask this because my planted tanks (70g and 20g) both run at 20 ppm or higher sometimes and I want to add neos and Amanos. I dont want to kill them. I dont overfeed, I change 50% of my water weekly, I dont dose KN03, I vacuum my substrate. I dont know why it is so high.

I replied in the other post where this was discussed, but I've thought about it some more. I regularly add the Easy Green fertilizer from Aquarium Co-op to my tanks if the nitrates are at 20 ppm or lower. I have either single strain or cull neos in all of my tanks, and amanos in one of them. I've never noticed any problems with either species.

Just for the record I have nitrates over 50ppm in my shrimp tank. The shrimp breed like crazy. But this is all from dosing dry salts like No3. Completely different than naturally occurring nitrates from decomposition. It's not the nitrates that kill the shrimp it's what came before it to get to 20ppm. Have you tested your tap nitrates?
