High Ammonia Help

  • We are currently upgrading MFK. thanks! -neo
I like the idea of a large drum...but have no where to place it. The tank is in my finished basement, and the drum would be an eyesore.
 
What is in the fx6? If you aren't running some sort of high surface area media i.e matrix, lava rock, or the like, then you don't have enough surface area. Additionally, using straight di water is detrimental to your beneficial bacteria colony unless you are doing water changes every couple of days. Your Ammonia is going up because you don't have enough of a colony. You don't have enough of a colony because they have no where to live. If I were you, I would fill up the sponge chambers you have, and any other space with decent flow, with lava rock.
 
I would also start cutting your di water with some tap. Straight di water is bad for fish, bad for bacteria, and bad for maintenance. What are the rest of your tank parameters?

The fx 6 has 2 boxes of ceramic rings and some carbon. And correct, i am using rodi water, which i have for the last several years. However, my water changes then were way way less frequent. I've never heard rodi being bad for fish, i thought it would be better. ..but, I'm open to suggestions. Also, Ph was the very lowest the API would measure, at a 6.0. Which is pretty low.

Would the marine pure block be a good addition to put into my sump? I think that's what it is called??? I beloeve i have a bucet or 2 of bio balls i could put into the sump.
 
Don't switch straight to tap. Sort out your Ammonia first by adding more media, then slowly add tap with each water changevery. You don't have to go all tap if you don't want to. The problem is, rodi water has no mineral content. Your fish need certain amounts of the minerals present in tap. Your bacteria also need those minerals. I'll post more on this a bit later. Maybe someone else can jump in.
