My routine WC was twice as week, of 25% , one on monday, one on friday with same water temp as the tank. and i run two external canister filters on the tank, one sunsun, one Eheim 2075 Pro 3 . dose with prime and TLC Bacteria .
@ snowman - yeah i had done 70% water change on monday, i have 2 internal filters pumping just above the surface to create tons of oxygen in the tank. nope that's the weird thing nothing has been added other than fish so i :dunno:
@ Ryanjury - thanks again man, i have just set up the 1.2m tank for the fish that is still alive. got wonder tonic and salt in it with internal filter cranking. so here's hoping what ever it is is going to be killed.
i did however also , drain all the water from the tank out, and start again in case there was something in the water that was causing them to die, though no one in the house uses fly spray or anything that is harmful. doors are always closed.
gave me ability to catch all the dead decaying fish that i couldn't see in between all the plants so that was helpful.
going to be buying a UV filter tmrw from HFF, mainly for peace of mind if there is any parasite in the tank hopefully be killed. along with keeping tank extra clean for when i get the discus, though that seems a long way from now, since this disaster :tears: plus be good for when i increase the lights, i read UV filter helps kill some algae.
From now on going to quarantine every single fish i buy, regardless of where it came from. So less learn't the hard way lol :tears:
would this be suitable or a decent UV filter? tank is 375ltrs
