Do you think assassin snails would take care of all of the snails in there now? there are a quite a lot in there of different sizes. What community fish will eat snails?
Another question I wanted to ask is about water changes, initially I was advised not to use hot water from my tap as it comes from the copper hot water cylinder and there may be high levels of copper or other unwanted parameters.
I want to go and find out about the difference between my hot water from the cylinder and the cold water from the tap, because if there is no difference this would make life so much easier for water changes - connect the hose straight to the mixer tap and set to correct temp, rather than boiling endless kettles of water.
What parameters of the cold and hot taps do I need to consider to find out if the hot water is usable?
