I am open to any good suggestions on a better filter for my 10g tank who's role is:
1. fry grow out
2. emergency hospital, and
3. QT tank for new purchases

So something that I can "adapt" not to suck up the fry - but does a really good job of cleaning the tank.

Are internal filters better than HOB for this size tank and it's uses? If so, tell me more??? I'm open to all great ideas from folks who are all more experienced than I am! Thanks in advance.

EDIT: the role of this tank is now SOLELY for fry grow out, and it's a planted tank. I've been told some type of sponge filter would be best - do you guys agree and if so, some recommendations on what pieces of equipment I need for this (I've only used canisters before, so I'm "sponge ignorant"!)

I would suggest you use sponge filter. Internal filters will often suck up your fry if they're not covered with a sponge or mesh. And so will the weak fish be. Weakened fish tend to have troubles escaping being sucked by the filter.

So a sponge filter would clean the tank well enough (biological and chemical) as well as being the best choice for fry, sick fish, or new quarantined fish? Any recommendations?
Yes. Sponge filter is sufficient for your 10 gallons. Make sure your tank is bare-bottom. That will be easier to clean and anyway, hygienic reasons is the main issue for all 3 of those purposes.:)

A fry tank, medical tank, and QT tank, a sponge filter is absolutely the best choice. The sponge provides food for fry. Removes excess waste and processes it. Provides oxygen which is needed in all cases. Easy to remove and rinse.

I would suggest, if you can find one, to get a sponge filter that is run by an airstone instead of the standard plug in the tubing big bubble type. You will get a lot more oxygenation and a lot more water movement.

Sponge Filters
The link shows some really good options for use in a quatantine tank/fry tank. With the multiple filters in one setup, you can remove half of them if you treat with something that is likely going to kill your beneficial bacteria and keep them in tank water to be put back in after the treatment. This keeps bacteria alive for a short time (48 hours or more I think with some circulation) so you can keep the tank going instead of losing all your beneficial bacteria.

Oops! Too late on the bare bottom! I have it set up with plants and gravel (about an 1 or a bit more), rocks, and caves. Right now it's a maternity ward... Three VERY pg platties are waiting, and waiting, and waiting - I fear their eyes will pop out they are SO HUGE!

So for even the fry grow out tank which has all the above - if I leave it as a grow out tank and have something that I can throw together quickly for qt or hospital (leaving the fry tank alone) - would you still only recommend a sponge filter for the fry tank? Would the type of sponge filter you linked be a better choice than the corner type that doesn't need an airstone (and you can put your own media in it)? I am going to replace the Aqua-Tech power filter on the fry tank and want to get the best choice. This tank will house fry from both the live bearer tank as well as the cichlid tank (much later when they are grown and spawning). So it's a permanent fixture here now. Just want healthy babies and a nice tank. Oh, there's a little algae eater who lives in there all the time now. He's the only "permanent" resident - everyone else will come and go like the 3 pg platties - once they finally give it up!

So if you kind folks would steer me in the right direction so I can get the replacement filter ordered... I would be ever so thankful!! :yourock:

Don't worry about that. What you did at the moment is correct. More hiding places will give them rest they deserve.:)

Sponge filter is still recommended. I would go bare-bottom if I were to rear them. Proper hygiene always encourages fast growth.

Hydro sponges are highly recommended. It's sponge so you can't place any media.

The advantage of the hydor stackable sponges is you can set them up in the fry tank so they are always seeded. Then when you need a filter for the QT tank, you simply take one or more off the stack and put it in the QT tank. Instant media rich sponge to help with ammonia.

The AC filters are the ones that can have the filter media replaced with many options.

The stackable sponges make great sense - I was thinking of putting them in the big tank with the fluval, but putting them in the fry tank makes more sense. I do have to say though that I absolutely cannot even think of a bare bottom tank. This tank is part of my office and the peacefulness of the tank helps me work - but the ugliness of a bare bottom would defeat the whole thing. That's just us (hubby is the same) - we're rock hounds and plant lovers as well as aquarists, so we simply HAVE to combine these loves into one pretty and peaceful tank. If the fry survived in the big tank with gravel and bigger hungry mouths, I feel they would survive in the same type of tank without the "predators" (mom and dad). I am just wanting to make sure that without the "forced air" circulation of a HOB type of filter, that the gravel would not get yucky faster with a sponge filter. I do have a small algae eater who helps with food in the gravel, and I do gravel vac - but now need to figure out how to gravel vac more "delicately" so I don't suck up the little ones. Of course, I suck it up into a bucket and check it before using it to water the plants with or flush down the toity if I'm not needing more plant water... Caution is my game and confusion is my name!

Which brand/model of air pump do you guys recommend? If I get the kind that can power two tanks, I can use it when I have to set up the qt/hosp tank. I just have zero experience with air pumps, so I don't know which one to purchase.

Also, what kind of air stone (is this the right term?) would I need for the nursery/maternity ward/fry tank with plants? Is a bubble curtain the way to go or some itty bitty little "stone"?

I have decided on the hydr-sponge, but would like the stackable kind - however it looks like the stackable version is only available for the bigger ones. True, or am I visiting the wrong websites??

I'm not sure if I've seen airpumps that can accomodate two tanks except using valves to separate the tubing into two. Hey, wait. That one will give you the idea.
If only I had a picture.:mrgreen:

Doesn't matter. You can choose whatever suits your choice.:)

I have 2 pumps with 2 outlets on each to run 2 different tanks. Either that or a descent one, not the smallest but don't need the largest, and a splitter to regulate how much air goes where. Run it how you like but remember the more air you have the more you have to fight with getting food to the fish unless you turn it off.

Ok, here's my tip for you if you want one airpump running on two tanks.
Buy a connector which has 3 entry points. You'll need 3 tubings which you insert one on the airpump and then the other end of it on the connector. As for the other two tubings, insert them on opposite sides of the connector and insert their other ends with airstones.

Here's the diagram:

Legend:
Letter "T"-connector.
Two small boxes-air stones
Lines-tubing or hose

Here's the selection of connectors:

Select the bottom one which is letter "T" in shape.

Gang Valves
Here is what I was refering to. Blue's idea will work but won't let you control the airflow. But there again, if you want full flow, I don't think it will matter because a descent pump will blast 2 bubble wands in two different tanks with or without a Gange Valve

Blue's idea makes sense. I have a biological sponge filter in a tank and an air stone in another which are powered by a single pump. I just use his system of tubing and valves, but i also have a small tap like valve that regulates the flow of air on each tube.
By the way i love your avatar and signature it reminds me of two siamese cats i used to own.

Oceane - Just when I thought I fully understood how a sponge filter worked I get your post. I thought if I used a sponge filter, I needed some type of bubble curtain or air stone in the tank WITH it... But your post makes me wonder. Could you please unconfuse me as to why you have a filter in one tank and the air stone in the other?

Thanks for the compliment on my avatar, my pretty little baby girl (little girl? she's 12 pounds and 14 years old!).

It seems in my analysis that Oceane was referring to the tubing, not tank. As for the other part, if you use what I made in the diagram, the airstones can be replaced with the hydro sponges. Sponges will still allow double function: filtration and aeration.:wink2:

:roll: Hi sorry for the late answer, i lost track of this post somehow. I have an air stone in a tank purely for decoration, and i use the sponge filter in another tank which i use as maternity. My sponge filter is a BOYU SF02 and the airstone is incorporated in a kind of plastic tube that supports the sponge.Ts and taps are fairly easy to get here, mine are unipet and were quite cheap. Greetings to your kitty does she really watch your fish?
