Yes these things are expensive and 99.5% of our work is major public aquariums. The homeowner inserts that we have done are extremely high end, otherwise we don't do them.
I am sorry that ufo_paul got the feeling that I am trying to sell things. If they had read my intro, I don't plan to sell anything on MFK, instead I am trying to show large setup and small setup to encourage members to try to do more introvative things. I am here to offer advice to members as they set up there own tanks, which I have done on many occasions now through email and phone calls. I have over 25 years experience in the aquatic field, so I have probably made many mistakes that you don't have to duplicate. I am sorry if you have taken it wrong and will stop show habitats if you feel I am trying to sell a product.
