So i've had this xenia in my tank for a couple months now and this has been an issue for a while. I started a thread
a while back and people said that it just looked like new heads were coming in so i waited it out and figured i would see what happened but I'm concerned that there is something else wrong with it. There seem to be places where the tissue on the base is eroding from something. A few days ago i noticed that in one place there was something green on the tissue that i assume is algae. I'm just not sure whats going on here. The top seems very health and continues to grow new "arms" at an alarming rate. Here are some pictures.
The green stuff is circled in red and the other places were the tissue is scarred is in blue.
ammonia - 0
nitrite - 0
nitrate ~ 20ppm
PH - 8.2
The only thing i add to the tank every once and a while is a PH buffer to keep the PH and alk
up. Salt water is pre-mix from the LFS
and is made with RO
. I know the nitrates are a little high (not an accurate reading still using the strips) but even with only feeding every other day what the fish finish in about 45 sec and PWC
weekly around 15% i can't seem to get them lower. Just not enough water volume and no place to put a skimmer in. My other tank info is in the signature. I think that should cover all the usual questions but feel free to ask anything else. Thanks
