Tunze Classic DOC Protein Skimmer 9210

[africangrey]

Roger,
I currently have an ASM G3+ but it won't fit underneath my stand, so I am thinking about switching to DOC 9210, how do they compare. what are the min and max water levels required for this skimmer, and would it allow ozone injection, is it ozone safe.
thanks.

The 9210 works on a closed loop recirculating prinicple and would not be an effective way of adding ozone, it also would be a very passive plankton safe skimmer and not comparable to an ASM, I think you would be happy with the 9010 though and it will work with Ozone.

Roger, what you said on the previous post is that basically the DOC 9210 will work with ozone but not beneficial, and the 9010 is the taller version of 9210 and will be benefited with ozone injection, is that right? how tall is the 9210, I have about 20 inch clearance. By the way, is the 9210 sensitive to the water level.
I currently have about 8" of water level.

The 9210 is not tolerant of varying water levels. The 9010 is. The 9210's closed loop system would basically not ozonize the water, no new water would enter to react with the ozone. It will be very close, the skimmer is 16.8" tall and you need 3.2" extra to remove the cup.
