is it meant to have a rotten fish smell?

It does smell a bit when first opened, its fine to use.

Heard so many good reports about this product but can it be used in internal filter, i have Juwel Bioflow 3 in 125L tank.

I was able to fit the sachet into one of the side housings inside a Fluval U2 pump (as supplied with my 90 litre tank). All I had to do was remove the sponge and carbon pad. It’s only been running 5 hours and I can see a difference already. I also dosed with Seachem Pristine.

How many of this for a 510 liter tank grams ???

Its treating up to 1000l so one should be enough you may need to recharged it quicker due your tank size
