Just Upgraded - What Filter For 50g?

    Hi Everyone,

    I just bought a 50 gallon aquarium to upgrade from my 20 long.

    What is a good filter to go with it? I was thinking Fluval 306, but it's expensive! I can afford it, but if it doesn't have any extra benefits over an AquaClear HOB or a Cascade 700, I'm not going to spend the extra money.

    I really want reliability. That's the most important to me. I would hate to have my filter go out and not have a cycled one to replace it...

    You can get a pair of aquaclear 70s (or a 70 and a 50 to save a few bucks) . That way you have redundancy.

    get an aquaclear 110 and call it a day, i personally use two aq110s on my 55g and a fx4 + two aq110s on my 125g. I prefer to overfiltrate my aquariums guaranteeing insane consistent filtration but i also have big fish

    Actually, I just upgraded to a 75G rather than the 55. I realized the 75 is as wide as my 20G long, and that's just too skinny for me. I want to be able to add depth to the aquascape. So I called the pet store and changed my order.

    Any suggestions on filtration now?

    You want your total filtration to equal or exceed a GPH of 400-500.

    A pair of Aquaclear 70s should work for that as well. They are 300gph each.

    I don't think that's enough filtration for a 75G. The 300gph rating is without media, so the actual output will be a lot less. I think a bare minimum would be 2 AC110 filters. A Fluval 306/406 (more bio media) and an AC110 would be a slightly better option and the best option would be a Fluval FX4. Petsmart often offers the FX4 on sale for $199. They don't advertise the sale online so you'll have to visit the store from time to time. The 4th of July sales are approaching so there's a good chance you'll see it on sale.

    Yeah, my mistake. Don't know why I was thinking 2x300 = 800

    I have 525Gph SunSun 304B canister filter and its not enough for 55g. On top of it I run small 20g submerged filter on the opposite side of the tank which helps to compensate. This is temporary solution, since I want to go bigger tank soon.

    *I have 20+ 2-4" fish so there is lot of bio load. So perhaps if you dont have a lot of fish, single 304B canister filter would be sufficient. Also you can get this filter under 80 buck of ebay. Ive had my for ~2 years and only had to replace UV lamp once which was 9 bucks on amazon and I clean it, every 3 months.

    Also to note I have this is my bedroom where kids sleep so its very quite.

    What's the bioload for this stocking?

    6 x Pearl danios
    8 x bloodfin tetras
    8 x rummynose tetras
    8 x neon tetras
    6 x panda cories

    My fiancé loves neon tetras, so she may want to add another school of black neons or ember tetras...
