I searched long and hard and couldn't find a thread dedicated to this:
How badly does an algae scrubber affect alkalinity? I found many mentions that theoretically algae growth can consume bicarbonate, but there are extremely few people complaining about low alk. If I install an algae scrubber, is my ca/alk balance going to be thrown way off? what can i expect? Is it really any better with an upflow design?
thanks!
