Planning to go with BB.

IMO I don't think it is a problem I have been reading BB threads for the past 1 1/2 years (new tank will be BB) and I have not read anything about drastic PH swings. I would be more worried about nutrient build up in a BB.
No it should be the same build up. From what I have read if the husbandry is not up to par they can go south quicker than a DSB...this is me said:Nutrient build up is worst in a BB?
