Oh, you REALLY want to read a lot of conflicting advice, don't you?  Well, 
I'll toss in my two cents worth:  rip the suckers out.  They do remove a lot 
of CO2 from the water, and their biological filtration importance is mostly a 
product of advertising hype.  Removing them abruptly causes a barely 
noticeable ammonia spike that is insignificant, and which lasts only a day or 
so at the most.  After that, the rest of the bacteria in the tank quickly 
catch up to demand and filter out all the ammonia.  (Well, you asked for an 
opinion, and that's mine.)
