ok i'll try siphoning out what i can now. i always have extra water ready to go so that's no problem.
considering these guys are jellyfish. it hasn't happened as much recently, but about a month back, every time i put my arm in the tank, once i took it out it would be very itchy almost like something stung it. could this have been the problem?
though it hasn't happened in about 3 weeks, maybe i'm either getting used to it or the population is fading.
