What’s up with the water?
I got a new 75 gal tank for my new RES along with a new fluval 407 filter. The water seems to be sprinkled with white specks all over and it seems to be more everyday. He has been in there for a little under a month and am wondering what it is. The filter does a great job at leaning out any poop or other debris but not this stuff. I was wondering if it’s shed because some pieces look like flakes and others just look like small white dots. What could it be and should I clean out 50% of the water?
PS. My turtle is ~ 2.5 inches, I have UVB, UVA, basking spots, and water heaters for it.
