Trade 75 for 110

  • We are currently upgrading MFK. thanks! -neo
personal opinion is i dont like tall tanks, only because of reduced surface area for gas exchange (Oxygen). The more you have the better it works.

Ye i couldnt agree more! I think width is far more important than height.

Get it done but while the volume is increased if it is the same footprint then you wont beable to have any more fish realisticaly because the surface area is still the same!


but that really depends on what you plan to keep.

if you have active swimming fish you will certainly be able to keep more fish.

if you have territorial cichlids that set up terrtories based on bottom structure then no.

I used to have a 90 and 65 gallon both with the same footprint (both 48x18 but 90 was 24 tall and the 65 was 18 tall) and I could put more fish in the 90..the extra water volume and swimming room made that possible..the 90 could handle the extra bioload..

footprint isn't the whole story..there are other factors to consider.

go for it and enjoy your new tank!
 
for the fish i keep, i wouldn't

same footprint = same surface area

No active fish even more than ever, you cant keep more because the surface area of the 110 is the same as the 75 so the same ammount of diffused oxygen in the water, but more volume so even less oxygen than the 75G actually so the 110 is goin to have even less diffused oxygen and so less active fish not more.
Buy it to give your fish a tad more room for manoover but dont buy it to add more fish!
Think about it its fairly simple

While it may appear that you can keep more fish you cant really especially if they have a high oxygen demand its just your perception.
 
Well really this will probably stay with the same population of fish. Which is minimal. The house is built with 2x12 on 12 in centers cross braced. The tank is between the 2 structural components maybe 4ft away from the 2 supporting walls each way.

you missed my point.

the point is that there are more variables in stocking levels than just footprint for gas exchange. Water volume is also a factor.

this is because the dissolved oxygen level we keep in our aquariums, whether it is a 75 or a 110 with the same footprint is in excess of what fish need to thrive.

even though the surface area to volume ratio of a 75 is more favorable for gas exchange over the 110, the difference is minimal.

dissolved oxgyen levels in a properly maintained aquarium should never be a concern.

its only a problem if your water quality (via nitrites, ammonia) prevent the uptake of oxygen from the water by the fish (ie ammonia can burn the gills and nitrite ions bind to hemoglobin to prevent oxygen uptake) etc.

when you hear people having problems with overstocking, its not because their dissolved oxgyen levels are too low.

its often because of other water quality issues that prevent the fish from taking up the available oxygen in the first place (something that an extra 35 gallons of water will help to prevent via extra dilution power) :)


I am not saying you can go crazy with a 110 vs a 75.

but you certainly can put a few more fish in the larger tank without a problem..
 
That's what I'm excited about is the "aspect ratio"? I just stay minimal on the number of fish because I don't have time to deal with much bio load.
