Sorry it took me awhile to get back on line.
I have some good news. My tank was serviced on thrusday, and a partial water change. I had alot of questions and concerns for my service person.
I don't have a "contract" with them, it is just a service call every other week. I have no obligation to them.
And I do agree, it is my tank and a very large investment. On the other hand I don't have the knowledge to tell them what is the best thing for my tank.
We have agreed that he will take has much time as he needs to teach me why and what is going on with my tank (w/o more $$). I feel alot better about the whole relationship. I do know, he has taken a personal interest in my tank, keeping a portfolio from the first contruction, for referances.
He had one great suggestion, "Get on line with AquariumAdvice.com"
