30 gallon freshwater - question

Hello all,

I just bought a used 30 gallon tank. The filter it came with is missing a few pieces so I am planning on buying a new one. What type should I buy for a 30 gallon freshwater tank with a sand bottom? I was looking at a aquaclear power filter, but I am not sure if this is suitable for sand and/or what size I would need?!?!

Also, the person I bought it off of provided me with the sand she had used before, am I safe to assume that I can re-use this sand?

Thanks!!

With the inlet tube strainer at approximately 4" off the bottom (top of the substrate) any power filter will work just fine. I quite like the AquaClear filters and have two AC70's on my 60g. You might also have a look at the Fluval 'C' series (also made by Hagen). Either would be an excellent choice.
Some recommend that you get a filter with higher than recommended flow rates in the confusion that better filtration is more water pushed through the filter. This is incorrect as the best filtration is filtering water a slow velocities through very fine media. I suggest you get the size filter the manufacturer recommends for a 30g tank to maximize filtration with minimum flow rates.

I would not start up a new tank with substrate from a previous owner. Although it may be fine, it may also harbor whoknowswhat. Sand/Gravel is very inexpensive, so start with fresh, clean gravel.

I second the recommendation for the AC filters. I would go no smaller than the AC 50 but the AC 70 would be much better. It would also work on a slightly larger tank if you ever upgrade or you could get a second one for a much larger tank. IMO this is the best filter as far as HOB's are concerned. I however have recently started really liking simple old school sponge filters. Effective, simple, cheap, and nearly fool proof. Downside is you really are limited in media selection unless you are inventive and a DIYer. Otherwise, they are great. Many swear by canisters too. They cost more initially, usually, but they are great. No experience using them but once setup and tuned in to your tank, they really get the job done well.

Thanks for your input. I think I am going to go with a AC 70.

Now.. for the substrate...

I did want sand, but I don't think I have the space to wash it (as I live in an apartment). What would you recommend for a freshwater tank? keeping in mind that i would like to have some live plants...

I'd still recommend sand. You can get Petco sand that doesn't need washed. You can also get a 50# bag of Black Diamond blasting medium (if you want black sand) and many people use it without washing. If you have a bathtub and a bucket you can wash your sand easily. Even if you have just a shower you can still wash it. IMO sand is a great substrate that works very well in planted tanks.

I have an AC 70 on my 30 gallon with sand. It's a great, quiet filter. You can get it much, much cheaper on Amazon than at a fish store.

I'm going to disagree with the previous posts about buying new sand. Having washed playsand, it's a huge, huge undertaking, and living in an apartment pretty much eliminates that idea :)

If you can find that black blasting sand, perhaps that is an idea. Can't find that at the Home Depot or Lowes around here. Sand in petstores isn't that cheap. Even on-line for washed sand, delivered, you're looking at about $40 plus.

If it were me, I'd take the sand you got, and rinse it well in hot water. If you have a way to let it dry before you put it in (spread out on a table) that would be good. Ich won't live once it's dried out. I'm not really sure what diseases you'd have to worry about. IMO hot water will kill most anything that could possibly be in the sand.

hmm... well the sand was dried, in a bag in her garage (inside the empty fish tank).

I am just worried about any disease being in the sand and it infecting my tank... but if it is safe it would be one less thing for me to buy.

I just bought a AC 70 on Kijiji (it is new) for $62.. I thought that was a pretty good deal, since they are selling the same one at a pet store here for $85

If you are concerned, boil the sand. You should be able to do it in batches. That will take care of anything that might still be in the sand.

Petco sand is a bit pricey, $17 for 20 pounds, you'd need probably two bags for your tank but it's nice stuff. It's what I have in my 75g tank. Blasting media is cheap, $8 for 50 pounds. Find it at a welding shop or Tractor Supply Co. I am getting that for my 40B that I am setting up soon.

I guess I should have mentioned that the $62 was with shipping... I am from Canada so it ws $25 for shipping...

I like the idea of boiling the sand... but I think I will need to add more, as there isn't that much in the bag..

(P.S....thanks for all your feedback )

If you only need to wash one bag to add to what you already have, it isn't that bag. Just takes time. You can do it a little at a time even in the kitchen sink. Really isn't too big a deal. It's worth the effort IMO.
