Thanks Triggerhappy but no apology is needed from anyone.
Words are one of the worst forms of communication when physical contact and sight are removed as meanings are lost in translation, what can seem perfectly reasonable to one may appear unreasonable to another. The use of smilies is there to help overcome this but some people will still not understand the meaning.
It's hard to resist the temptation to jump down someones throat when they've done something you know is wrong or they're planning on doing something silly. That comes across in the replies no matter how hard you try and disguise it. We all know that we are not here to put people off posting, scare people away from the hobby or to ridicule them. We are all here (I hope) to offer all the help we can to others that share the fascination and enjoyment of the marine worlds we create.
We all make mistakes and will continue to do so, we'll put the wrong thing in the tank, do the wrong procedure, overdo this, underdo that. It's part of the hobby.
If you make a thread you have to be prepared for people to argue what you've done, point out mistakes, etc. The best thing to do is ask them to explain their view if you disagree or ask for help to remedy the situation if you think they have a point. The person may have been down that road before and is simply trying to steer you away from disaster rather than just being nasty.
We are all in this together so I would urge everybody to think before hitting the reply button, re-read your reply and look at it from another perspective before posting it. There is more than one way to get your point across
