Prime is used to control other things than Chlorine & Chloramine, the recommended dose is what you should use, regardless of what your area levels are. I'm adding 0.8ml to each of my water change containers, so even using all 3 once a week I'm only using pennies worth :)

Dahn sarf is where I live, but it's still the best value for money as far as I have seen.

I live Oop North, in the best county on Gods green earth, I don't drink but do enjoy a weekly Tandoori Mix grill, which costs £7.95, which is pretty much the same as 250ml of Prime...I know which lasts longest! :)

Thanks for all your replies and suggestions.

I've chucked the out-of-date lot :cry: (sniff!) and because it was water change day today, popped into my local P@H and bought a bottle of Tetra AquaSafe. Not the cheapest option, I know, but easily dosable and it seems to work very well.

This now gives me time to put in an order for Seachem Prime.

Another question to the chemically minded: on the Seachem Prime bottle it states it ''detoxifies ammonia, nitrite and nitrate''. Does this deprive the bacteria of their food, i.e. no ammonia = no ammonia munching bacteria? And does it also deprive plants of nitrate? Simple answers for a simple mind, please. I'd rather listen to a math formula being explained to me than chemistry, never got my head around that one [woo]

No it doesn’t deprive the bacteria or plants of any food, it converts them into non toxic (ammonia into ammonium) versions which bacteria and plants still take up happily. Its also handy in an emergency situation (eg ammonia spike) as it can be dosed at 5x the required amount to nullify any toxins rapidly.

The Tetra stuff is good, just expensive, I think its a given that Prime is the best all round product! I would suggest you get a few dosing pipettes or syringes that have 1/10 ml graduations, so you can accurately dose your new water. I use 30 litre drums to hold the fresh water, this only needs 0.8 ml of Prime, so its important to have accurate kit :)
I add fertiliser and liquid carbon every day, as learnt on here, which also needs 1 tenth measurements
