fluval 305 for 55 gallon ok?

[PerFiikT]

Is this filter ok for discus? I know you can't have to much current but I'm pretty sure it has an adjustable flow

I have the same one on my 60 gallon, but i also have 2 aquaclear 30s for a little extra filtration.

i'm brand new to discus but i use this fluval and a penquin 200 for my 75g

I've used a 305 for years on a 45 gallon, no problems. You might want to fill all three media trays with biomedia and not bother with any other stuff.

305 is a great filter! got it on my 55 planted np at all

[hawaiidiscus]

only problem with canisters is they go anaerobic quick if the power quits...

I have a Fluval 305 on my 60 gallon tank. I agree with Don in Virginia to just use biomedia in the baskets. The other thing that I would recommend is to have plenty of spare parts.

I just got my first discus juveniles yesterday. I have 6 blue turquoise x pigeon blood born on 2/21/2011. I have a fluval 305 for my 55 gallon. Does anyone know if it is a good idea to adjust the flow rate down, or should i leave it at full blast all of the time?

I also have 50 pounds of gravel, not sure if that makes a difference.

[DonMD]

You can adjust the flow rate down, but not more than 50%. As long as the water is passing over the biomedia, everything is fine. As for gravel, I think most people here on simply would recommend that for growing out juvies, a bare bottom tank is the best. You can harbor TONS of bacteria in the gravel. Once they're grown out, you can set up a display tank with gravel, or my preference, sand, and other decorations. But growing out your young fish requires lots of feeding and cleaning! ! ! GOOD LUCK!

[JustinJDH401]

Thanks Don. I decided to turn down the flow rate only during feeding so the food lands and i can siphon it up during my daily water change and not fill up the filter too fast. As for the gravel, I have gradually been removing it each day. 50 pounds is just too much.

If you put the intake and the end that pours out towards the center and not each side, you can have it on full blast and have no current.

IME, this is not actually true. One of my pairs spawns regularly on the intake pipe of my Fluval 205. When the eggs are due to hatch I turn the filter of at 0700 and then turn it back on for a few minutes at 1700 (when I get home from work). If the wrigglers are on the pipe I turn the filter on for a few minutes every hour until I go to bed and then turn it off until the next morning, then repeat the process.

I have performed this process 6 or so times since April and everything is going very well.

Also, if there is no power, the Fluvals can be hand pumped for a short time every couple of hours which maintains a flow through the filter. Some of the Eheims have this feature too (not the 'Classic' series though). I have also done this when we lost power due to a 7.1 magnitude earthquake.

yeah that's thefirst I've heard the anaerobic thing too. Maybe if it is filthy and off for over 24 hours, I don't think anaerobic bacteria populations grow that fast.

[zimmjeff]

might want to put in a sponge filter just for backup.

the more filtration you have the better for discus, if it says up to 90 gallons and you have a 90 gallon tank I would get 2 of those
