Just thought I would post this information as it may be useful to some other fishkeepers:
"Enzo Household Ammonia" £1 for 500ml bottle 9.5% ammonia 90.5% distilled water
It's readily available throughout UK, but is produced by Lausco Services in Wales (I phoned them today to get this info and they were very helpful). Contact details are: Lausco Services Ltd. http://www.lauscoservices.co.uk TEL: 01446 775577
I've been having great success with this ammonia during my current new tank fishless cycle (see other post in the Tropical forum) and as its pure ammonia I dont think I'll have to worry about any phosphates, chemicals, perfumes, etc.
Edit: Got some more info through from Lausco today about the Ammonia: PH = 13.0 - 14.0 RELATIVE DENSITY = 1.0 - 1.1 AQUATIC TOXICITY = LC50 96h < 1mg/l VAPOUR PRESSURE = 760 MM Hg at 20 degress C. COMPOSITION: 10% Ammonia Solution Irritant, Xi (R36-37-38) ("not sure what those numbers above mean, but thought Id put it here for the boffins amongst us" )
While we are on the subject I happen to have quite a few syringes that we've got with childrens medicine over the years but where can you buy things like syringes, pipettes, test tubes and other associated equipment?
I got my syringe from a Chemist, and I believe most well stocked chemists will keep them.
Also, I got a whole bundle of old test tubes, syringes and pipettes from a school which closed in my area. Perhaps schools have these sitting around as surplus and would welcome a local fishkeeper giving them a call?
