Ned,
I have a 40 gal breeder. (2) Chocolate Cichlids and (6) Aureum. I have been just using buckets and a siphon for water changes (~30% ever 2 weeks). I _ out a section of gravel with the water dump out the water then replace the gravel. I am finding lots of crap still mixed in with the gravel...Would a gravel vac be better. I was looking at those ones that attach to your sink..Do they work?...Do you carry them? How much?
Thanks
