Clownfish has lumps that go away and come back.

[Dlaw]

Hi everyone, I'm new here and to the hobby. My tank is a 45g tall (should have done better research, a 40 breeder would have been so much better for this space), with 2 ocellaris clowns, a firefish, chalk basslet, falco hawkfish and flametail blenny. It's about 3 months old now.

So, as the title says, one of my clowns has lumps that come and go, and sometimes they look like pimples (as is the case today). They'll be there for a couple of days, then just disappear. I don't see him/her flash, it's eating normally and no other fish exhibit any symptoms. Is this something I should be concerned with? I do have my quarantine tank set up, and I tried to catch him this morning with no success, but is it necessary? Is this Ich?



Apologies for the crappy picture, hopefully you all can see it.

Looks like lymphocystis and often associated with poor water quality and/or diet
What test kits are you using and what is your ammonia-ph-salinity and nitrate?

I'm using the API master test kit and master reef test kit. Refractometer for salinity. Ammonia is 0, PH 8.1(ish, between 8.0 and 8.2), salinity is 1.025sg and nitrate currently is trace. I have been doing 5-10g water changes twice a week as I've been combating an algae outbreak, and just did one yesterday. Nitrates don't get above 5ppm before I need to scrape algae.

I've been feeding a variety of frozen foods. I have mysis shrimp, squid and a variety pack right now. The variety pack has bigger cubes, so I cut those in half. I feed once per day.

Edit: I did forget to mention that my water does appear cloudy early in the day, but clears up a couple of hours after the lights come on. Is that indicative of something wrong with the water?

I tested my tank again today, as I forgot to write down when I tested Wednesday before the water change. The tests came out the same, except for my PH dropped to a flat 8.

I'm not sure what, if anything, I should do.
