Quite right, however algae is one of the prime sauces of the spores that can infect people with Legionella Disease. This is a particularly unpleasant illness that makes Corona virus look like a runny nose. Is it worth risking you health for a drop of bleach as a preventative? There is another way around it without a mechanical syphon. Fill a tube with water from the tap and put your finger over the end. Lower the other end into the water jacket and then remove you finger when the tube is lower than the bottom of the Nova. That is the way I empty my JOBO processor after film developing. In fact with the later ones (My new one is is only 6 months old) there are no level plugs on the end plate, you judge the water level by sight glasses so emptying the water jackets will be a long tedious business with no other holes to allow air to enter at the same time Last edited by John King; 29th February 2020 at 10:09 PM. |

Some very good points! Like I said I love my Novas. I don't intend to slam them. I think it goes without saying that most darkroom products can be improved upon greatly and it's no different for nova slots. Best of luck on your search nat, if you find a good mechanical siphon let us know, that's definitely something I would be interested in. |

The syphons work for me - that's why I recommended them!
And I've just used my syphon recently, to empty most of the liquid in some of the chemical slots, as it's much quicker and more efficient than the tap, which I then use to empty the last little bit of liquid. It would be interesting to hear the OP views, as well as from anyone else who bought one. Terry S |

Legionella is a bacteria, not a fungus. While there are pathogenic fungi (and bacteria) they are very much in the minority and we are currently covered in billions of the little buggers (and always have been) and we have all managed to survive this long. Saying all that, I put bleach in my water baths too!
Yes, been using an aquarium siphon for emptying the nova slotty thing (amongst other things) for years and it works fine for me (actually I am on my second one as the bulb part tore on my first one). Alternately, fill a length of tube with water in a bowl etc. Put your thumb over one end and lift it out of the bowl of water by that end keeping the other end submerged so it is the last part to exit the water - the water should stay in the tube. Dip the open end all the way into the water jacket and drop the "thumb" end below the bottom of the tank. Remove your thumb and watch the water flow (might be a good idea to do this last bit over a suitably sized bucket ). Last edited by Bob; 2nd July 2020 at 02:53 PM. |
