Question Switching to a sponge filter questions

Ok, so if I do get angelfish for my aquarium (strongly considering it) I would like to breed them. Everywhere I read says I need a sponge filter so the fry don't get sucked in, since I have a power filter right now. But a sponge filter only provides biological and mechanical filtration, not chemical. To have chemical filtration, I need carbon. So what's the solution? Anyone with a sponge filter out there? And I would put the sponge filter in with my filter I have now for at least a month before taking out the power filter, so the bacteria have a chance to grow, but would there be a way to speed this up, like with "filter muck"? Any help would be appreciated!

I added the sponge filter after I already had the BioWheel on the 14 gallon that is still cycling. I am going to have both. Definitely do not take the back filter off because that is where you have your good bacteria right now. I am pretty sure I am going to get Angels for my big tank. If I was going to breed I would still keep both the sponge and the canister filter (yours being back filter) going. I would use a prefilter sponge for the intake for the canister filter. You can do this for the back filter intake as well.

Regarding the carbon, I always had carbon in the past. However, I have recently read that if you do live plants carbon is not good to use all the time. Even on the Eheim instructions it says to only use the carbon when the tank is new and after medicating, etc. So, I guess the carbon thing won't be an issue if you decide to not use the back filter, but I would keep the back filter on there and when you get the babies just put a prefilter on the intake.

Also, I was not experienced with breeding Angels....had them breed when I was a kid. I remember that they can be good with their young but can turn on them and can decide to eat them. I think mine started to eat their young. You may have to separate them anyway. I don't know enough about this part though. I remember separating my Guppies and Molly fry though from the parents. Although, you would still need that prefilter on there for when they first hatch.

My first goal is getting them to spawn... I think I would rather have the parent angelfish raise them, so if I can't sell or give all of the babies away, there won't be much of a problem. And only the biggest and strongest will survive, good if you're trying to keep the line strong, bad if you're selectively breeding.

And a prefilter? You mean like a cover to go on the filter tube?

P.S. Did the ammonia go down today? I am sick of the wait too. I am waiting for the Nitrites to go down on the 14 gallon. I think my 56 gallon was cycled right off because of being seeded but I do not want to take a chance. I has been cycling for a little over 2 weeks now with no sign of ammonia or Nitrites. Just a little Nitrates. The fish that I had to take out of my daughter's cycling tank are in the 56 gallon. I am going to get may a fish or two this weekend....if I can decide what I want to get for Angel Fish roommates. I am not going to get the Angel Fish until the thank shows me positive signs after getting another fish or two.

It is kind of hard to find....but any sponge that can fit over the slitted intake tube of the canister or back filter.

I would rather have the parents raise them too. I cannot remember how well they do this though...the chance of them not eating them. I remember one time though that the eggs got fungus on them. Some will some won't. That is why you will see them fan their eggs with their side fins (forget what these fins are called). This helps the eggs from getting fugus. I vaguely remember everything. It was before I was a teenager, but boy was I into fish. I really studied up on them. I think I remember putting something in the tank to help the eggs not to get fungus. For some reason I vaguely remember experiencing Angel fish breeding again when I had fish as an adult but I don't know why I am thinking this because I don't think I had Angel Fish. Not sure why I remember some of the things better when I was a kid then when I was an adult 13 years ago. LOL

Who said you need carbon? Sure wasn't me...LOL

I have had sponge filtration ONLY with no nothing added in several set up (mainly the one's 30g and less) and it works great for my tanks and plants and raising fry

You'll find a good overview of sponge filters here Sponge Filters, Filters | Pet Solutions your local pet store chains usually carry them too. I guess you have a air pump at home already? Otherwise you'd need to buy one, but don't get nothing high end wattage there or it'll bubble the fish out of your tank

When you change over, you can also just rinse out all your old filter pads in that very tank till its all nice and super mucky water and then add the sponge filter (its clear back up in round about 1 day).

Alternatively if you'd like something larger scale, googel Hamburger Mattenfilter and built you one of those real quick, works great on larger tanks and wonderful for fry too.

Just a guess with no measurement, I'd say the ammonia is probably around 0.25 - 1 ppm. It really doesn't matter, the nitrites are still off the charts. But it's all good. After one HUGE water change (once it all becomes nitrates) it will be ready for fish!

Sponge filters are great, but they really don't do much at all in terms of mechanical filtration. The water flow simply isn't high enough to make particulate stuff stick to them. They're good biological filters, though. Personally, I only use sponge filters as the only filter on the tank for really un-messy fish like bettas or fry-only tanks. Since you'll have the adult angels in there, I think you'd be better off with an HOB and/or canister filter with a sponge prefilter.

You may wanna just consider keeping yur HOB and buy a sponge you'd get for a sponge filter (they are round maybe 2" dia and 5-6" long) and just pull it over you water intake!? Just a thought.....

@Iambatman....very true, but what really rocks for larger tanks/ messy fish are "Hamburger Mattenfilter" they act like a large sponge while giving your the mechanical "boost" of a canister...googel it I loved them when I had time to built these things for my tanks.
