I know, thank you for telling me about that, much appreciated! I changed it last night even though the water is pretty clear now. Just till Saturday when I do w/c's.awwww, those are some cute cories!!
and all that gunk on the paper towel is what could have been in your impeller, messing with your filter. it sure did clear up quick!
with sand substrate, the poop and mulm will sit on top and won't go into the sand at all.Truth to tell, I'm not to happy with the sand I bought, it's very fine and hard to clean. I used the python this morning and all you can do is just swirl the opening over the sand, you can't get into the sand. I don't like how it cleans up, not good enough for me. Maybe that's why I'm having water problems now.
