Yeah if only Pond Boss advertisers could give advise I guess I would be in trouble!
As my air system I have many don't like or care for but I still give out advise on it and it still is working for me and others I know too. Like other mods have said just do your best to say or tell that person you are NOT an expert and your just giving out advise based on your expierence. Folks need to know this and really should assume it unless you have told them otherwise. Nothing is for certain in the world of ponds.
