Here's an update, I made fresh salt water with
RO/
DI water (that's all I use now in the tank) and Instant Ocean salt mix. I tested it for phospates before adding it to the tank and there were no detectible phosphates in it.
I did a water change and have cut down on the feeding.
It looks like to me, overfeeding has to be what's adding the phosphates??? Fluff recommended defrosting the frozen mysid and other stuff and draining off the water in order to avoid adding phosphates from the water in the frozen food. I did that and it wasn't as hard as it sounded.
I'm adding phytoplan for the filter feeders once a week or so, but using water from the aquarium to mix it up. When I add a buffer for
ph, (not very often at all) I'm using water from the aquarium to mix it up.
Also, I was alternating flake food and the frozen food. Assuming there are phosphates in the flake food, I cut that out and will only use it in a emergency.
That's about it for additives, so assuming I change the water every week for now with
RO/
DI water, don't add flake food, drain the water off the frozen food and cut down on the feeding, this will eventually get the phosphates down.
Also, got rid of the SeaClone and added an AquaC Remora Pro skimmer, which seems to be working VERY well.
Does that sound like a complete plan or is there something I'm not thinking of?
