L066 with White Spots

[jzcombo]

I need help identifying a problem with my L066:

Everything started going wrong about a month ago. I had a case of cyanobacteria growing in the tank. By the time I researched enough to do anything about it, I noticed a couple fishes with the ich.
I raised the temperature in the tank to about 84F to combat the ich, kept the lights off for about two weeks for the cyano, and performed daily water changes. Few casualties from the ich. But while resetting everything back to normal, I noticed my pleco has a white spot close to his dorsal fin. Flat to the skin, but we'll defined as a problem. And a week later, the spot is still there and a second portion is starting to become visible.
Also, his eyes are outlined by a faint white line. Never noticed before.

29L planted tank
1 opaline Gourami
1 sparkling Gourami
1 pearl Gourami
3 yo yo loaches
2 tetras (what is left from the school. Did have 5 total)
Clam

Ammonia 0
Nitrite 0
Nitrate ~10
PH 6.8
GH 2
KH 2
PO 10

Currently AquaClear 30 HOB with purigen, sponge and the biomax that came with AquaClear
Weekly 1/6th water changes

I have three foods that Sink to the bottom, Hikari algae wafers, sinking wafers and sinking carnivore pellets. Other food that is in the tank is Hikari dried tubifex, brine shrimp, and blood worms. Also Thera+. The food is fed sparingly and is alternated daily to mix it up. I haven't started using vegetables yet.

Normally the temperature is ~79F. Right now at ~83F because of the ich.

No treatments used for the white spot on the pleco. Turning the lights off removed the cyanobacteria, while raising the temperature and daily water changes cleared up the ich. I also added a bubble line while temperature was increased. Light is back on now. Ich is gone. Not sure which direction to go with the temperature for the pleco issue.
