My tank had been cycled and then I noticed that my ammonia levels had risen to .50 ppm
. I added a bunch of LR
to help improve filtration but have not seen a change. Ammonia levels still read .50 ppm
. I have lots of coraline algae on the rocks and only 2 damsels currently in the 45 gal
Originally I had 45 lbs or rock and now its more like 90 - 100lbs. The new rock that I placed in the tank was cured and purchased locally so I assume any die off was minimal. The newer rock has a good amount of algae growing on it and is pretty much indistinguishible from the older rock. That last bunch of LR
was added about 1 month ago.
Anyone have any ideas of what could be my ammonia source and why that much rock is not effectively lowering the ammonia levels?
I feed a small amount of food every other day. I have decent sized clean up crew consisting of a star fish, red/blue leg hermits, peppermint shrimp and astrea snails.
All other quality measures are reading zero (Nitrite and Nitrate).
