ok to turn off filter at night?

I have HOB's on my tanks and can't sleep with them running at night. HOB's allow oxygen to dissolve into the water even when they're off, so the bacteria don't suffocate.

Hmmm.. my snoreing usually will block out any noise of a filter for me. I sleep like a baby. ;)
 
That's an unneccessary risk to take when you can probably get a better filter for like 30 bucks.

Especially the day you forget to check the filter in the morning and it doesn't start on it's own :(
 
Dank, unless the plecos are huge, that's not a large bio-load for a 46g. You'll probably be fine turning the filters off overnight.

Good idea to keep tetras in small schools.
If your guppies are opposite sex, I'd suggest two more females.

fyi, plecos can get 12+ inches. At which point, the 46g won't seem large anymore. You may consider sending one back to the pet store before they get too large. One common plec is fine for 46g. ...and they are solitary creatures, so are quite content not being around other plec's.
 
well the problem is this, the hanging filters will not be submerged in water that will be aeriated by the air stone. Anyone will tell you, you shouldn't turn the filters off at night but if you find it nessicary then, it would be ok. the bacteria in the filter sponges will most likely die unless the are unaerobic bacteria, but there will still be plenty of bacteria in the tank and it would stay at a high enough level in that size tank. with turning off the filters, you may get a smell from the stagnent water and the debris in the sponges on the hang-on. It will depend. you will also have to do more maintainance on the filters, but if you need to the nit would be ok over night. Also when feeding your fish make sure it is about 2 hours before turning the filters off, this will mean that the fish will have had enough time to digest the food and poo, and then the filters will be able to suck it up, this means you will not get an amonia spike. also i doubt that you would get an amonia spike, the bio load just isn't that big, and it would take longer than 12 hours for the tank to start to produce ammonia or nitrite or even nitrate bacteria.
