I have (well, had) two healthy frogspawn colonies that were rapidly growing in my tank. One bleached out (seemingly randomly) so I moved it to low light and not really noticing an improvement. When the other started bleaching, I noticed it started at the tip of one of the heads and slowly spread like a disease (when I've seen a coral start to bleach usually the whole thing lightens). Upon closer inspection I noticed what look like waminoa flatworms (see pictures). I am wondering how to deal with these guys -- I'm happy to dip the coral again but unsure if it will resolve the problem. I have ordered flatworm exit (scared to try but willing) to help with eradication, and if I can find a pre-quarantined wrasse that will eat these guys I'll also order (TSM has an eight line, will that do the trick?). Just looking for guidance here as I've dealt with flatworms in the past but not this particular kind.
Secondly, I added a few "easy" SPS frags to my tank in the past month. Oddly some RTN'd and some STN'd almost immediately upon being added to my tank, despite existing colonies of hammers, duncans, pocci, torch, galaxea, blasto, acan, BTAs, various encrusting LPS, etc thriving. Shortly after this, I noticed one of my established montis paling and dying. Then I noticed the browning of a relatively established and rapidly growing jack o lantern lepto. The coral below it (see pic, forgot name) also appears to have a couple very small patches where it has lost flesh but coral itself appears healthy. I also noticed some darkening of my green pocci but the coral still appears healthy.
I did notice some dark spots on one of my pocci's (see pic) -- not sure if bugs or not. Neither healthy pocci colony is RTN or STN.
I'm trying to figure out what's going on here. In terms of chemistry, here are my notes:
240g tank 7 months running, seeded with 2yr established rock
No large alk/cal/mag swings (alk = 9, cal = 460, mag = 1350)
Very gradual salinity dip from 1.026 -> 1.024 over a few months, and slowly brought back
No detectable nitrate/phosphate (annoying)
Low bioload, feed every day
Most corals were growing rapidly but have stopped now that these symptoms have come about (I know this from measuring alk consumption)
No changes to lighting schedule, though T5 bulbs might need replacing
Problems did appear around the time I was using Selcon
RODI recently tested at 13-14 TDS (crept up on me i guess). I live in SoCal and I'm worried chloramines have made their way to tank water
The affected frogspawn. Head on the right slowly bleached from right edge to left, doesn't appear to me like light or chemical related bleaching but who knows.
Flatworms
Dots on pocci
Darkening of jack o lantern
Any help or thoughts would be greatly appreciated. I have ordered an ICP test. Thanks.
