Black spots on artificial plants
Ok I have a 25g freshwater tank. Artificial plants, all levels look good except nitrates which are around 20 which I was told was ok, but to me the water in the tube looked a little darker than usual so it may be a hair higher than 20. Anyway, I used to have algae eaters but the one I had for a long time (3 years) died and got a new one which promptly died and then 2 more in behind each other that died within weeks. I was told that it was because I didn't have enough algae in the tank for them to eat. So I just didn't get another one.
Now however I am seeing little black spots on my fake plants. I am guessing this is algae? As I said the water levels are all great, I maintain the water changes every week, I have 6 fish total in the tank so they aren't over crowded. We live in TN which I was told has a high copper level, but it doesn't seem to bother the fish and I do add a water additive/treatment. So...should I get another algae eater now? Or perhaps a catfish of some sort to at least take care of the food that gets to the bottom of the tank? I honestly don't know what the black dots are and they aren't like ALL OVER the tank. Just on one or two of my decos...mostly fake plants.
I am planning on doing a partial water change to get the nitrate level down some, and will change the bio beads in the filter then as well as rinse the sponge out good. I just changed the charcoal so that doesn't need it. I just don't know what this is and/or how to treat it. Also I noticed today that they are ONLY on the underside of the plant that sits directly in the path of the filter waterfall. Not sure if that matters or not but...

I would also perform partial water changes on the tank to get nitrates as low as possible.When in doubt, do a water change.

Ok I have an AquaClear 70 (which I understand has been "bought out" I believe by Fluval?) Anyway, are you guys saying I should NEVER replace any of the internals? Such as the BioMax inserts which are the ceramic rings, the Foam Filter insert, or the Activated Carbon inserts? I understand about just rinsing the foam insert with the tank water...but should I not ever replace anything?
EDIT: Also, I removed said plastic plant and guess what? It's specks of black paint. I guess they tried to make the plant look more "real" so they put little strips and splotches of black or could be dark dark green on the leaves. I will try to get pics but again my camera kind of sucks.
