Hello everyone.

Flatmate is not happy with the ASAP 300 Internal Filter that came with our 54 litres tank and he wants to buy a new one.
Advice please.
 
Is this for aesthetic reasons, ie external filter?

Also might want to consider you're still cycling your current filter/tank so changing filters at this stage will require a bit of thinking about to change it over.

Cheers.

High tech/CO2 injection or not? If non CO2, low tech, low light etc should be fine unless you plan to overstock it with fish

I don't know what that even means...
Just a beginners tank .. with a simple set up....
7 fish a snail and a few amano shrimp... (thats the plan)
 
Yeah if you can run the new one alongside the old one for a week or two it would be beneficial, alternatively depending on the type of filter you get you might be able to use some or most of the filter media from your old filter in the new one.

Once your current tank matures a bit it will build up a beneficial bacteria colony in the actual tank which will be helpful. Also as the plants grow in they'll help out a lot. So swapping filters won't mean you're back at square one.

I might be over cautious but when I've changed filters and re used say 50% of the old media I still do water changes every other day for the first week just to ease the pressure whilst the bacteria in the filter catches up.
 
In the main i agree with you Hufsa, the only caution I'd add regards leaving the new filter on for say 6 weeks is an assumption that after this time the new filter would be fully matured and able to deal in full with the tank bioload.

If two filters are running then we have to assume "all things being equal" that the tank bioload will be shared between them. Eg there's only enough food to feed a certain amount of bacteria.
So ultimately when the second filter is taken off line the new one will have to start playing catch up anyway.
I suppose if you were really cautious you'd slowly de commission the old filter but in reality that doesn't happen.

Just my thoughts and could well be mistaken.
 
Eden 501 external canister filter OR Eheim pickup 60 internal filter

I've used both of these in small tanks and they're both pretty cheap and good value for money. I prefer the eheim pickup as the eden 501 comes with clear tubing that you end up having to clean more often as algae and sludge builds up in the tubes. The Eheim internal filters function well and are easy to maintain but are much more obtrusive in the tank.
 
Do you want an internal or external filter? Internal goes inside the aquarium, external goes outside, usually inside a cabinet which the tank sits on. If you have the space and money, external does look nicer and you can get a bigger one that has better flow and capacity for keeping the water clean, but internal still works great and is much cheaper.

I have an Eheim Classic 250 external filter on my 60L and I am very happy with it. I use lily pipes on the inflow/outflow pipes so it looks more beautiful.

If you want internal, before that I used an Eheim Pickup60, it worked really well, I only swapped over for the aesthetics. I still use it on my quarantine tank.

On my 54 litre nano I use a JBL cristalprofi e702 which maybe overkill for a small tank but it was knocking around in my garage for years having received it as a gift when I subscribed to Practical Fish Keeping magazine.
The filter is super quiet and reliable and looks fine sat on the floor next to the tank- I show it off as if it is an ADA Super Jet 😜
 
Any Advice? i'm looking for a canister filter to a Ada 45p tank. Saw a Youtube clip from Greenaqua were they setup a small 45p tank with oase biotherm 250 canister filter. Is it reasonable?

Rather than keeping both filters running, you can easily place your ASAP 300 sponge (and any other media) in the new filter - just look at the direction of flow (usually bottom to top) and place your “cycled” sponge midway along the path

Filter media
Example Filter Media
  • first layer is usually mechanical
  • next layers are often biological (or a mix of the 2 functions)
  • uppermost layer is often a fine mechanical, and may include chemical “cleaning” media such as carbon (particles such as Seachem matrix carbon, or Juwel carbon sponge) or purigen (Seachem - Purigen which needs to be placed inside a bag Seachem - Zip Bag)

This path is easy to see in canister filters, but can be less clear in Hang On Back (HOB) Filters
