Bio Tabs (Pods) .... Spain

Yes  into  the  "Holding  Tank"  they  go,  But  even  at  the  low  cost  of  them  I've  never  delayed  the  emptying  of  the  tank  altho'  it  gets  fully  used.  I  do  not have  a  special  Flush  Tank  --  in  my  van  it  comes  from  the  general  water  tank,  so  I  carry  a  Half  litre  spray  bottle  with  whatever  takes  my  fancy.  Some  use  the  'pink'  stuff,  others  take  a  quantity  of  Lenor  or  some  such,  others  "Zoflora"  --  it  really  depends  on  your  nasal  sensitivity  

Just  one  thing,  if  I  may  ask  you  please  not  to  use  the  term  'Tabs'  it  confuses  some  newcomers  --  It's  better  I  think  to  refer  to  them  as  " Gel  filled Bio Pods "  -  no room  for  mistakes  there

ABM, I was referring to the Motorhome grey waste tank, not the wc tank. Our waste tank holds 100 litres but can get smelly if you leave it for several days.

I am a convert to Gel filled Bio Pods for toilet tank and very pleased with results. Re suggesting using in motorhome waste water assume this is where washing water etc goes. How do you get it into the enclosed tank?

M, there should be an inspection hatch on both the fresh and waste water tanks....for cleaning and 'inspection'....or even a good hose out, periodically.

just drop a gel pod into the waste tank via the inspection hatch.

Too right about the confusion  - the first time I trie I bought tabs and they are terrible all sorts of fillers etc.  eventually used them up washing the dog beds!  Gel every Time!  

Ah,  Now  I  understand    !

You  can get  Waste  Tank  Cleaning  Fluids  from  most 'van  accessory  outlets  but  I  only  apply  that  if  the  'vans  not  going  to  be used  for  a  while  --  generally  I  use  a  strongish  mixture  of  hot  water  and  the  nicest,  smelliest  washing  up  liquid  I  have  available  !!  But  there  are  some  folk  who  use  and  swear  by   a  dissolved  tablet  or  two  of  the  sort  used  in  "Dish  Washing Machines"

Back  in  the  "Olden  Days"  I  believe  it  was  Hot  water,  washing  soda  and  a  fast  drive  round  Silverstone  or  similar  --  cleaned  the  tank  out  a  treat 

Not sure of the rights and wrongs of using these but they seem to work for us and yes they do smell better than the blue stuff which we get and also use from Aldi at a good price £4.99 for 2Lts on offer at the moment till stock run out that is.

Re waste water tanks - I have read in the past that using cheap cola works well but have no personal experience.

Cheap cola cleans the pipe work pretty amazingly so probably tanks too but no idea how much.  I bunged the end of waste pipe and filled with cola and left for a while.  Excellent result and that was after using a Mr Muscle or the like. 

Well, OH just bought a bunch of bio tabs to try out. I am OK with Aquachem but the tabs will be much easier to handle. We shall see.

I do have grey waste tank cleaner for the Motorhome but it is expensive and yet another bottle to handle. I should think you could dissolve a tab in the sink and just let the water drain out into the tank.
