Bio Tabs (Pods) .... Spain

Is it the gel pot ones or the cube looking ones? I keep meaning to give them a try, then forget which ones to get. 

Do they get rid of coliforms and other enteric bacteria?

Its the gel Bio pods.

Sounds like I cannot, not give it a try (if you will excuse the double negative).

Perhaps in such relatively concentrated amounts the enzymes are quite happy the break down the remaining "food" in the contents of the tank.

Got to agree with most of the above have been using the aldi ones for a couple of years now would never go back to the smelly blue stuff

I have just seen Lidl are offering their Formil Bio (and non bio) at a big saving this weekend. 4th & 5th Feb.    £1.49 for 20 tabs (normally £2.69

Thank you. 

This sounds like an interesting idea. Would I be right in assuming that these Bio-Tabs work equally as well in caravan cassette toilets as they do in motorhome tanks?

Is it just a case of adding the usual 2 litres of water and dropping 1 tab in the cassette?

Yes, it is as simple as that and my experience is with using it in caravans.

I put a bit less than the 2 litres in as it is me having to empty it, so the lighter the better.

Thank you for the info. I'll give it a try.

Do you still use 'Pink' in the flush tank? I did read on another site that toilet "Blu" blocks can be used in the flush tank as long as you remove the covering first. I've not tried that idea either.
