If it really is the ac70, it will be fine. IF its the ac110 you'll be more than fine. Ac70 does 300gph. Thats a 10x turnover rate per hour. More than enough.

right now, the stock is undecided. its not for my tank, im givving it to my friend to start him up in fish :)

he really wants a neon liek bright colored tank, so were not sure yet.

Does this filter need activated carbon??[/QUOTE]

Awesome!

This is somewhat debated on this forum. Myself, and I believe the majority of MFK, believes that carbon is not necessary in a healthy tank. It has its purpose for medicines and other toxins. In my experience, I feel that it is not necessary and takes up space in the filter that could be used for more biological media. I currently do not, and haven't for some time used carbon. I have pretty healthy fish and choose new stock as wisely as I can and have not had anything that couldn't be treated with higher temp and salt.

Last, but not least, that filter will be fine with a 30g tank full of neons.
 
Although there are different types of biological media available, I would suggest just getting some cheap ceramic rings or the ones that Aquaclear sell at petsmart or petco or any other lfs. Honestly, you could put some other mechanical media in there as well in place of the carbon to help with water clarity since a tank full of tetras carry a fairly small bioload. As far as how many tetras you can fit in that tank? Not really sure myself as I don't and never have kept neons. I imagine many, and since you'll have good filtration you could put a few extra in there.
 
Yea, I know what you mean, spring semester starts like NOW!!!! Just make sure he or you understand the cycling process and the nitrogen cycle. If the filter has established media, and you add a small number of fish, you probably wont have an ammonia spike. If you replace all the media (which I would not recommend, at least leave the rings in there that you have) you will have to cycled your tank.
 
YES IT DOES! im excited lol

well this filter may have been used for like random stuff, idk i rinsed out everything in teh filter with regular tap water. if we get all new stuff, but keep like half the old sponge and the ceramic that is already in there, would that be ok to add a few fish at a time after the water cycles for 24 hours???
 
Since I don't know the exact history and situation that you're filter is in, I would advise that you get your tank set up and test the water parameters. Buy an API test kit, they are the best, it's $30 or so but willl last for a while. Whatever you do, just keep your bio media in water and circulating. Bio media needs waste to stay alive. Whenever you set up the new tank, just watch your levels. Check them everyday. If you're reading 0 ammonia, 0 nitrites and some nitrates, your media is cycled. If not, you have to go through the whole process again.

7" across the front of the filter, and 4 1/2" from front to back.


if its the 70, would yall say it would be ok for a 30gal?

Based on your dimensions for the filter, it is an AC50.


  • 7"L X 4"W X 6 1/2"H with 2 1/2" of its width behind the tank.
  • Rated for up to a 30-50 gallon aquarium 200 gph
  • Warranty: This filter has a lifetime guarantee against defects in materials and workmanship. This is does not include any replaceable parts such as impellers, cartridges etc.


As for filtering and cycling, even though the filter may be established, by adding regular tap water to the tank itself will set back the bacteria, causing it to have to cycle again. It may not take as long, but it will still go through a cycle.. Please do not add your fish until it cycles.. I add ammonia and fish food to my tanks to get them cycled without having to use fish.
