Yep that's the one I have got ( now my mate is using it) I managed to pick it up in store

.
Might be worth ringing your local shop to see if they stock it, or you could go to homebase.
Good luck with the cycle
Im 90% sure they will have it, our boots is in the trafford centre and its stupidly massive. It has 2 Giant floors lol, but will ring beforehand but thanks for the replys everyone = D . Quick question, will this 500ml be enough to cycle a 30L tank? and i dont need anything else right?
Hi
Interesting to hear you're from Manchester....I'm based in Salford - currently close to finishing my fishless cycle (my log is somewhere on the forum if you are interested!)
I used the Boots at the Fort and they actually had it on special at the time so I got it for 45p!

Its worked fine for my cycle and I'm almost finished with what feels like more than 2/3 of the bottle left - if you are anywhere near Salford you are quite welcome to have it if you can't get hold of any nearby.
Good luck with your fishless cycle...
Regards
Phil
