<p>I tested today my 1 liter batch of rapid fixer on a leftover film leader with the method mentioned above. The fixer has been trough 18 rolls of HP5+ so far and the clearing time was around 55 seconds. First time seeing in real time what is actually happening with the film when it is fixed, so the test was also a nice science lesson :) <br> I will keep testing every 5 rolls and see how much the fixer is worth using. <br> I will try and report back, though I don't know how much time will take me to shoot and develop another 5 rolls.<br> Thank you</p>

Ok, thank you all for your fast and elaborate answers. Will test the fixer and adjust based on my findings. Maybe I will go Ilford way and have 2 batches of fixer, one fresher than the other, and use them both in conjunction. Thank you again.

Hi all, New to the forum and new to home film development. I have a question regarding the usage of Ilford rapid fixer, that might be a no brainer for some, but not very clear to me. Ilford rapid fixer fact sheet states that unreplenished solution is exhausted after 24 rolls per liter. So, if I make 1 litre of 1+4 dilution I can use it to fix 24 rolls. If I use a Paterson 3 reel tank with 3 films inside, does one fixing session of all 3 films count as 3 rolls towards exhaust of the fixer? So I am left with 21 rolls worth of fixing strength from that 1 litre I made? Not sure if my explanation was very clear, please bear with me. Thank you
