Red-eared slider expert advice requested...

:swear:

So I had went about and changed the tank maintenance routine for the red-eared sliders we have at work (1 per 200g tank, a 6" and an 8")... then the animal's boss-lady takes the little turtle to the vet, and he tells her to start rinsing out the filter with tap water every 2 weeks!

I had just got them to stop that routine to preserve the bio-filter!!! (sponge in waterfall pump)...

Am I wrong here? Is shell-algae a terrible affliction? Is there any reputable turtle sites cause I can't find any.

Thanks... I guess that makes sense. The 'creek' beside where I work is about 10x as toxic as when they declared the great lakes officially dead... and yet I still see wild western painted turtles and their babies! Party hardy turtles...

Would you see the algae-shell as threat or peaceful coexistance?

okay thanks guys... one more complicating factor, even though it is a 200gal, there is only about 30gal water in there... and sometimes there can be 1-24 goldfish-feeders for our 2 16" pike... so I was thinking that for the fishies a good biofilter would be better than their routine of rinsing out the filter with tap water every 2 weeks...

It was the feeders with the turtles, the pike have their own 300gallon where they get fed about 5 feeders each twice a week. So haha, I was right about the turtle tank needing biofiltration! Take that animal lady and vetrinary misadvice!
