I have a Tunze nanostream 6025 power head which provides the perfect flow for my tank but recently has caused problems. I sadly lost my Dragon Pipefish when he got sucked in the side vents And today I rescued my new baby spotted Boxfish who was also stuck to the side of the power head but luckily I noticed it and brushed her loose. She seemed fine after so it must have just happened but now I’m super worried as I have a new Banded Pipefish as well and I don’t want them hurt. I have temporarily put a black nylon stocking (pantyhose) over the power head but I’m not even sure if this will fix the problem? Or damage the powerhead? And I think it has slightly lessened the flow but I’m not sure. Any ideas would be much appreciated. I will attach pics of powerhead and of course baby Clementine as she’s just too cute!!
