I now have two nerite snails in my tank and there is poo everywhere!!! I am doing a wtaer change tomorrow as my nitrates have gone above 40ppm. Ammonia and nitrites remain at zero.

Obviously I will be able to root through the gravel with my manual vac when I change the water, I just wondered what was the best way to get rid of the poo between the water changes?

you dont need to really, if you do a small water change every week or two, just enough to remove any debris you can see. most waste will break down and get used up by the plants, so dont worry too much, your tank does not need to be sterile, also snail poo is fairly well broken down anyway.

Okay thanks :)

you will find they will poo a lot when first added to your tank as their will be an abundance of food for them but in time this will settle and they will feed normally best give them an algae wafer every few days after about 2 weeks of adding them
