Algae during CP treatment?

[ReefHog]

I have three fish in a 20gal hospital tank I treated with CP Friday morning. (3 days as of now) It was up sterile three days prior to adding CP. I'm starting to notice what looks like algae growing on two pieces of PVC. I got the CP from my Osco pharmacy in pill form. I dosed three 500mg tablets which should work out to 900mg of Chloroquine base. That would be 45mg/gal, slightly over the 40mg/gal recommended dose. Is this normal or should I be worried? Of the three fish two (filefish, Hawk fish) were completely unaffected by the velvet outbreak and are just in there being treated so my DT can go fallow and they are not carriers. One fish (niger trigger) was not in good shape a week ago but is looking better every day now. He ate mysis for the first time yesterday and is finally swimming around all day instead of hiding. See below. The water is a tad cloudy I attribute to the binders in the pills.

Glad your Trigger is doing better! Algae like that is normal in a QT. Easiest thing to do is to clean the pvc outside of the tank. Wipe down the walls if it pops up there with one of those Mr Clean Eraser pads.
I don’t use CP, but perhaps a small UV filter like the Green Killing Machine would work. Let’s see if anyone else knows if UV would hamper the CP from doing it’s job #reefsquad

You definitely wouldn't want to run a UV during CP treatment. Risk of degradation of the medication.

The algae and cloudy water is a concern as CP is an algaecide. So technically if the CP is therapeutic there should be no algae present.

That's my concern. Water is clear. Just not crystal. I shouldn't have said cloudy. Without no real way to test, I'm wondering if I should up the dose a bit. I should still have some wiggle room at 45mg/gal right now. And all 3 fish seem to be doing good and eating. I think i'll make a 5gal batch of of new CP treated water at 60mg/gal. Then siphon out 5 gallons from hospital tank and replace. Thoughts?
