I'm by no means an expert, especially where it pertains to water chemistry (Oracle system design & development, yes just not water chemistry
) but from what I'm seeing you have a TDS
somewhere between 150 & 220. The TDS
out of my RO
is 0. My TDS
going in was roughly 150. I don't see measurements for PO4
or Nitrate and those are going to have a great impact on your ability to control nuisance algaes. I'm not sure what affect the Alk
& pH levels will have on your tank.
What I can tell you, based on my experience, is that I set my tank up with tap, switched over to LFS
bought water and then had a crisis where I was changing ridiculous amounts of water so I went back to tap. After that I bought a RO
and now I mix my own water. In my sand, up against my glass I have some cyano
growing. My guess is that there is something from the initial mix of water that is feeding the cyano
in my sand. Whatever the cause, it isn't rampant in my tank at this point (and it seems, much to my surprise, that my blue leg hermits love the stuff), but I have a fairly good feeling that the water in my tank is mostly RO
at this point. What would my tank look like if I had kept on using tap water? Dunno but I'm glad not to have to find out!
You could start by testing your tap for NO3
to see what you've got coming out of your tap.
I also see that you have some aluminum in your water. I don't know at what point that presents a problem to corals, I just note its presence.
