i agree with you completely, i surely hope that is the cause
man... i tell ya, i have not had this sort of mass death since ages ago when i first started getting heavily into the hobby - growing pains, embarassing really!!
IME too, that IAL tend to take ages, last time i used them, it took literally a week before the wa ter started to brown!
this one, straight away.
i bought it from the same person i got it from last time, i have 40 leaves left, i will not use it and discard it.
dont wanna take that risk again!
if its not the cause, then i am stumped!
but the patter of use vs the symptoms starting coincides - that is the only thing different i did in the tank!!
i will not feed anymore today or tomorrow and test ph twice daily. i turned up the water changer slightly to get the ph back to normal and have it stable.
no other fish has suffered any ill health at all what so ever - arowana is very active and hungry, spotted metynis are fine, plecos are fine, eel etc
but what i did see, is the parrot scratching itself a few times this morning before i took out the IAL.
maybe coinsidence. but who knows.
i lost 2 large ones at least worth 250 to 200 each today, and 10 smallish and medium clowns in the past coupel weeks!! half of whcih are oddballs - 2x 4 stripes, couple with weird patterns and 2 spotted clowns :tears:
i believe i may lose some sleep tonight
