I was thinking about making a sump for my 72G Cichlid tank. I am extremely un-educated on sumps. all i know is that they help harvest BB?? if im wrong then please correct my thoughts on this.
If i were to do one, what would be the benefits, are there any draw backs.
There are positives and negatives to sumps. Honestly, if you tank is doing well with canisters and HOBs, then there is really no benefit. A sump is just another type of filtration.
i feel sumps more efficient may be because of its capacity to hold more media or more rooms for different types of media and also a large surface area which helps in the growth of beneficial bacteria well canisters also does the same but still i favor the sump filtration more.. just my experience
