hope i have put this in the right place will try and cut a long story short !
3 weeks ago i got a new 47g U.K tank used all gravel decorations filter and water from old tank and just topped up with fresh water (old tank was 23g) fish all fine water readings as normal
ammonia 0 . nirtite 0.
nitrate 5.
all was well except one molly got a bit of fungus so put her in Q tank and treated with myxazin it contains dye which having never used it before didnt worry me , have completed the meds and molly is back with chums no problem but i cant get my water in Q tank clear i have run carbon for 48 hrs and it still looks like pea soup! I did a 50%
water change with no effect the water in Q tank reads the same as 47g (i use liquid test ) . the Q tank is 17g(U.K) is this the meds or is a coincidence and i now have an alge problem or bacterial bloom ?. the Q tank is an established tank (9 month ) and i have never had a problem with it . it is rarely used as a Q tank as i dont often have poorley fish but i use it for new fish or fry or if nothing else i put the man mollys in there to stop having millions of them (bless them) its been green for nearly a week and and i am very depressed about it as the other two tanks look crystal clear and other than meds i have not done anything different . all tanks are weekly water changed 25% . sorry it a long post and confusing hope someone can help ! thanks
