On my 29g planted aquarium I'm pretty sure I've overstocked on my fish considering I have 1 blue gourami, 1 angelfish, 8 gold skirts, 2 corycatfish, and a bristlenose pleco, but I do have 2 filters running. My filter setups are

Fluval Aquaclear 30
-prefilter sponge
-foam sponge
-activated carbon (to remove the yellowing caused by my driftwood)
-biomax

Fluval Aquaclear 30
-prefilter sponge
-foam sponge
-2 biomax inserts


Is that enough filtration with the fish that I have considering I have 2 filters and plants? Does having plants help with the bioload? Or should I run a third filter? I already have an Aqueon Quietflow 20 laying around and I could probably just use a different filter media in there.And I don't want to just buy 1 big filter because multiple filters are handy when one gives out or anything like that.

Just to add I also do partial water changes every week to compensate for overstocking and once in a while I'll even do it twice a week.(I find water changing to be therapeutic lol)

Plants do process the bioload and much more effectively IMHO than any man made filter.

What really matters is there you're happy with the filtration and tank.

In my systems I use no mechanical filtration or circulation. Just use the plants for filtration.

But that's just my .02

You can run a tank without mechanical filtration? Do you have any issues with cloudiness in your tank?

Yeppers

no cloudiness as well.

With no circulation stuff just settles down on the substrate.

I think the filtration is fine..maybe even overkill, but as long as the fish aren't getting swept around and struggling to swim, they'll be fine. :)

I wouldn't include carbon if you have live plants, the carbon removes important nutrients the plants will need to absorb. If this is just temporary to absorb the tannins though, you should be fine.

And I'm not sure an angel and a Gourami together in such a small tank is a good idea. I have heard not to mix the two.

You should also keep at least 5 cories. :)

Thank you for the reply. I'm glad to hear that my filtration systems fine. The angel and gourami are actually doing fine together and they actually stay on completely opposite sides of the tank. I think it helps that I have plants that they can hide in. If anything I can most likely give the gourami to a neighbor who is starting up his own tank.

Is it true that carbon will steal nutrients from my plants? I'm considering just adding more biomax and some filter floss to substitute the carbon

Zero is zero - if your ammonia and nitrite levels are zero (and clarity is good) then you have enough filtration. Does that mean you will always have enough? No, stock changes and fish grow.

That's one thing carbon is for. It does absorb funky colours and avoids odors, but it also absorbs heavy metals and other things that are in the tap water and fertilisers added for plants.

Carbon is fine for non planted tanks, but it strips too much from the water to be good for plants.. And pretty much nulls out any added fertiliser that's in the water column.

And what may see says is correct. As long as your levels stay stable after cycling the tank..you've got enough filtration. If your fish are struggling to swim and getting blown about, you need to dampen the flow. If you can't dampen the flow enough then you've probably got too much filter.

I ran my 28gal with only a single sponge filter and it was adequate. I didn't have an angelfish, but I had two schools of tetra/rasbora, a school of cories,, and then depending on the timeframe, either a Gourami or a ram. With a full grown angel I would've probably upped the filtration, but you've already got much more than my one sponge.

Thank you all for your input. Is it too late to add more corys because they're not from the same tank?

Yep.

if you have ammonia for instance and carbon is absorbing that, then the plants have less ammonia.

But with enough plants you have 0 ammonia so who cares.

But what I do in no filtration so all that goes to the plants.

Beaslbob, so far I'm getting pretty inspired by this no circulation tank you're telling me about. Perhaps this will be my next side project? What type of species do you have in this tank?

No, it's not too late.

Don't take this the wrong way, but asking such a question leads me to think that you would be much better off building your experience in traditional fish keeping practices before moving on to alternative methods. Of course that's just my opinion.

I've been fishkeeping with my dad for years, it's just corydoras are a completely different species than the cichlids me and my dad kept. I bought a school of peppered corys, all but one survived. Then I bought a school of melini corys and all died but one. I made sure temperature and other water parameters are to their liking, yet only a sole survivior of each school remains. Now I'm stuck with two corys. I'm wondering if I should bring them in instead and try for another school. For some odd reason corys are the only fish I've been baffled by.

Without even reading page 1 yet of this post I must point out .. You likely have a MUCH better idea of proper tank care then bob. If he linkiked you to his thread.. Please read it all the way through. This method is absolutely terrible!! If you want a better versionof the same idea talk to aokashi or look up Diana Walstads methods! Diana is local to my state and while i dont use her methods that are factually proven.. I 100% agree with how she keeps her tanks. She is worth a read. And while she does natural planted tanks she mostly doesnt agree with no circulation .. Nor does she agree with no water changes.. Just few water changes. And unlike bob she 100% back the use of a water conditioner .. Specifically prime. Listen to an expert.. Not just some random person on a forum who NEVER posts pics of their current tanks! Last thing I'd wantbto see is anyone coming here fir advice then being mislead so far.

Thanks for the input. I'm always open to learning new methods in fishkeeping. Not everyone uses the same techniques and a lot of people have used methods that were against the norm, yet they have successfully raised perfectly healthy fish. I was considering bobs methods since I was trying to find a way to have a low tech tank. I'm for sure going to look into Diana's methods. I never jump into something without the proper research. This forum is just one of the multiple resources I have since everywhere people say different things.

guppies, platties, angelfish, hachet fish, neon tetras, plecos, danios, glofish, ciclids, goldfish.

marine--tangs, clowns, gobies, banguii, soft type corals.

hope you correct the spelling mentally as you read. :lol:



Just about any.

With some fish the you may have to setup some kind of refugium to seperate the plants and fish. But generally just about any fish can thrive in these environments.

Hello
There seems to be some confusion in this thread as to what is filtration and what is circulation.
taking circulation first circulation is the movement of water in the water column. it’s simple if water is in motion then there is circulation and in tropical aquariums there always exist currents ( currents is the circulation of water). These currents are thermal currents and they exist every where water is heated. This process of thermal currents only requires a heat source and gravity.

Filtration is a little more complex. It is generally accepted that there are three separate process that filter our aquariums. 1) mechanical filtration, 2) chemical filtration and 3) biological filtration.

Mechanical filtration is the filter media that we change out when it becomes clogged. The rating of mechchanical filtration is NOT PARTICULATE removal but the amount of water that passes threw the pump. Your filter rate should move the water column at least 4 times an hour.
a drawback with this type of filter is it collects suspended particulate and allows the captured particulate to pollute the water column and it also breaks this particulate into smaller and smaller sizes as the particulate passes through the filter from the forceful currents created by the water pump. In my opinion mechanical filtration operates toward keeping the water clear.

Chemical filtration is basically adding carbon to the filter process and is valuable because carbon has the ability to remove pollutants from the water column that are chemical in nature. Most folks don’ t use carbon but I find it useful filtering and it provide a great surface area for beneficial bacteria make home.

Biological filtration is the only filter process that is necessary and it is the filtration that beaslbob uses. Biological filter is the nitrogen and carbon cycle. When you cycle your tank you are setting up the biological filter and it is the only filter you need.

I'm also confused, you asked if you could add cories to the tank or if it's too late since they aren't from the same tank. You mean the same tank from the LFS? If you have room you can always add more cories.. They appreciate the added numbers, even if you add them later. I've done this several times. It's best to get the same specific species, but not necessary.. I always tried to make sure they had similar adult sizes though.
