thats my tanks last test date havent used it in a while so just wondered if it needed to be tested aain as im not sure if its a 5 year test or a 3 year test anyway id be really happy if someone was able to answer this for me cheers
Is the retest date for the start or end of the month shown? I have a 0.8L bottle dated 2006/10 so it expires in October. Would like to know if I have to get it tested now or can wait until the end of the month of expiry?
