well im doing it any way so maybe a pointless question but i went to get some salt and Ro water from the lfs today and a friend there basically told me not to bother with marine its very expensive and huge amount of work. I was a bit taken back by how much he disliked marine lol but i think its worth the effort am I right here but if water changes are regular and you take care and re search every little thing you do then am I right in thinking that I should be ok?
