Thank you again, Dorothee. WOW! You have quite a set up in that room! I don’t have any available furniture for any new tanks to rest on, that’s why I asked. I keep thinking there must be some kind of special shelf unit available specifically intended for aquaria. If not, there is a “hole in the market”.
Since no one has answered me about the eichen extract brand, I’ll post that question elsewhere.
Cheers,
Jonette
