Hi there, I'm new to the list so please, bear with me.:-) I've seen on the marine sites that it's possible to use a coil(tube)filter for nitrate removal, has anybody tried this method? Would a faster flow in a longer coil have the same affect (but reduce the likelihood of blockages)? I'm sorry, but this may be quite a long posting as I've got a lot I want to talk about (sigh), I'm in Spain and it seems nobody is very interested here.:-( Does anybody know of any European breeders of Dwarfs (Dwarves?). I've found a local importer but the quality and conditions leave a lot to be desired, they also only stock the more 'normal' Apistos. Thanks for the space, if anyone's in the area give me a call, Colin ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
