Well looking like won't be getting my green and red/orange montis spiralling up together as looked like red one was stinging green one every night and killing part off it off where they meet and then red one growing over green one,then few weeks back did water change and sg was little low and I know not to add salt directly to tank with livestock in it but have done before adding to overflow in dt so got longer to travel before getting back to dt and never had trouble but this time added some heavily salted water in small jug that only mixed for a minute or so by twirling around in jug so not really mixed at all and added to second chamber off sump but could see the crystals quickly go through sump into pump chamber then back to dt pffft then next morning see the green monti bleached white on the outside edge of it where new growth was since owned monti then next day completely white but red monti just fine,but looking these last few weeks since and see a tint off green to it here and there so we'll see ^_^
Did take this video as looked like a little critter/insect dragon fly looking thing clinging to edge off bleached monti,looks like couple off legs holding on with long slender body and other things I thought looked like so some mad critter or just algae and my imagination running wild ha ha
