Could I ask for some advice with this problem please?
The batch of Isinglass was mixed up 3 weeks ago and stored in the fridge. I used it in a stout 4 days ago without any problem, just a few floating islands but on the pale ale I've ended up with this:-

As usual I mixed the solution with about 2 pints of beer and poured into the carboy. Should I leave it, as it is clearing or rack and repeat with a new batch of isinglass?
Cheers
