Hi all, im new to this forum and to fish keeping as well. I have just bought a new 3 ft 30g tank.
I need help on choosing a filter, i think i might get a hang on filter since im not made of money.
I was also considering a second internal filter for biological support. Do you think this is advisable?
Also i was thinking of sand as a substrate, i dont much like he look of gravel.
I've never kept sand before so i need help on how to clean it and keep it safe for the fish.
Please Help!
hi there.

to the forum...
With your filter, i suggest you look into a cannister filter. It simply sucks up water through an intake tube, goes into a body full of media and substrate (meanwhile, water is being cleaned) and then is pushed back out through the tube to the tank again.
For that type of aquarium, it may be worthwhile to look at an eheim. They are the most reliable, well worth filter you can get. A professional II2026 should be sufficient (maybe pro II 2028 a little more, but not much), only if cost isn't an issue...
Tertratec is apparently a very good brand for the cost. You ask anybody on here about them, they would reccomend it to anyone.
Fluval have a good name, but not a good reputation

They are known to leak, cause floors to be flooded, and the list goes on. However, their new models (105, 205, 205, 405) have replaced those old models, and are said to not leak at all. If you do get fluval, get the newer model (to make sure its the new model, a dvd on how to set it up should be included). Maybe a 305?
Just re-read, you like hang on the back filter. A lot of people like the eheim liberty ones... i have a dynaflow 3, i think its excellent, but people have different opinions on different filters. Aquaclear are another good brand... Maybe someone can suggest more (i have no idea what lfs sell overseas cause i am in australia)
As for your substrate, many people have sand... it looks much better than gravel, and the fish like it more. If you do end up getting sand, make sure you wash it well... Put a small handfull of sand in the bucket with water, swish, empty, redo, and on with the next handful. It is a long process, but rewarding when you see all the effort put into a nice looking aquarium (it took me 10 hours to wash all of my sand, mainly because it came from a river - and no, there were no pollutants. It was clean, just dirty!)
Anyway, enough of me ragging on. Hope everything goes well with your tank!
