On your instructions below it says use 25ml per 1,136 litres but on bottle it says use 10ml per 1,000 litres which one is correct please ?

Good morning. For Pond Klear Xtra we advise using 10ml per 1000L of pond water. I hope this helps with your query. Kind regards, Envii

Does this have to be continually applied or once the bacteria have worked are they are there for good?

all i can say is after six weeks my pond cleared and has been gin clear for two months and shows no sign of clouding i also do not use any filters on this my fifth pond get the plants right and you do not need filters.

How much do I need for a 10000.00 litre pond please.

Hi, 25ml per 1,000 litre, but we recommend double or triple dose initially to help bacteria dominate the bad bacteria.Especially after a warm winter when loads of organics in the pond, if it is in a bad way consider also using Envii Sludge Klear in conjunction to boost bacteria levels. Key for success is getting good bacteria dominating bad bacteria, and you can only do this by numbers. Please feel free to call me during office hours on 01246 240880 if you wouldl like to discuss in more detail. Andy

Does this contain bacteria to control nitrate levels? i use nopo2 to do this, but that's expensive. would this do the same via controlling no3?

As per my other answers, this stuff is next to useless. Look for Blagdon pond products
