How much aeration needed?

wrote: Yes, another question ... When starting a planted tank with a few fish. How much aeration do I need? I want to minimize surface turbulence to keep the injected DIY CO2 in the tank. I am using a canister filter. When I make the spray bar move the water without disturbing the surface I get bubbles and some living things floating at the surface. When I move the surface around, the stuff seem to disappear. I quit aereation about a year ago. I got tired of the mineral deposits. All of my tanks have high densisty popultions: that is over 1 inch of fish/1 gallon of water. I worried the first few days and watched closely for any movement to the surface. Never happened. One of my good decisions. I love the bubbles, but hate the mess. dick |

Canister filters are known to move a lot of water - most types of aquatic plants that thrive in nature, grow in slow flowing or still water - plus, algaes do better in a turbulent enviroment. That is SO odd. My experience is the exact opposite. It must be specific the the kind of plants and algae. The only place long, fluffy hair algae grows in my whiskey barrel pond is in part of one barrel where the water is relatively still for the water lily. The water hyacinth is much smaller in that barrel too. OTOH, the anacharis sitting right in front of the spillway in strong current was growing like crazy and blooming heavily last summer. I also get tons of hair algae and blanketweed it in the calm, sponge filtered outdoor tank. My mollies and flagfish love the stuff so I don't worry about it. Indoors, I have clumps of java fern sitting in the filter outlet, and they grow faster than the java fern on the other side of the tank. The only place algae grows along the back of my 10 gallon tank is tangled in the baby's tears where the current is light. Again, it's clumps of fluffy hair algae - the kind that's not really attached to anything. Maybe it gets carried to the filter in current? I generally put crypts in moving water too, since all the pictures I've seen of them in nature is bent over from the current in fast-flowing streams. They seem to do fine that way. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |

How do you make sure everyone who buys your bettas provides them with live plants and gravel? ======== Sorry, I forgot you had asked this question..I was so excited about your boy's larger housing that I totally forgot you asked about this. When I gave to people, they were either neighbors, friends, etc andf I hardly ever charged them. However, word of mouth people that came to buy I charged a very nomimal fee and it was usually less than what the current price at the shops were. I would ask them about what size tank they would be going into, as well as explain the proper care if they didn't already know. When I was breeding with regularity (yrs ago), it wasn't like it is now. Bettas were given proper care and kept in tanks with common community fish. I was raising them in NYC (60s/70s). At that time they were kept in small glass ivy bowls that held about 8oz of water. It was very cruel but the stores said they had no choice. Space was at a premium there and still is. Those who knew better had them in larger bowls with some gravel and at least one small plant of some kind. The bowls were actually either used food jars, cookie jars or regulation GF bowls, cheap then. People hardly ever kept them in small bowls. Of course some did. However, it really wasn't the norm, nor were they even near as popular. Not even close! NetMax probably remembers this, as well as other old time hobbyists who have been in the hobby as long or longer than I have. ( since the 1970's). There may be regional differences in their care. Here in TN they still keep them in ivy bowls and sell people these small bowls to keep them in. Most bettas don't survive very long. I know this because of what people I meet say. I always hear something like this, "Oh I had a betta once. It lived about 2 months [or some other time-period less than a year]." If somebody were to tell me that they wanted to keep it in a little bowl I would simply deny them the fish. Plain and simple. Folks who didn't already know the proper care were educated. Heck..back then I the smallest tank I can remember there being were the AllGlass 2 1/2 gallon ones. Not sure on if they were out in the 70's, as I used 5g's back then for tiny tanks. I always remember there being 2g tanks. My mother bought us a 2g Metaframe tank in 1952. It had a SS light and a plastic bubble-up filter, gray gravel and a few real plants. She bought us guppies. I barely remember the GF bowl and the 2 GF that died in days prior to that. I must have been very young. Someone clued her in that fish can't live in bowls. I remember she would change the Angelhair fiberglass filter material, carefully feed them. That little tank hooked me for a lifetime. :-) I can't remember exactly when they switched from SS framed tanks to all glass tanks. How about anyone else...I can't remember. Back then people didn't have these tiny tanks to choose from or those horrible contaptions they're selling for Bettas these days. Those clear plastic things that have an area that's almost a V shape in the middle for the Betta to be housed in. It holds like a couple/few ounces of water. These things are horribly cruel. The stores here have all kinds of tiny over priced plastic bowls for Bettas. :-( The place I got mine said they were around 1/2 gallon each. They weren't, and I never gave it a thought because the fish did so well in them. I even stopped going to one of the local shops because he started selling these things. He got all excited when I walked in one day and couldn't wait to show me these new Betta "tanks". I did one of these faces...= O I said..I can't believe you are selling such cruel things and walked out. He knew better too. He's a local shop trying to compete with the chains around him and I'm sorry, but he could have done better than that. There's many 1g set ups with even a light that he could have sold for less money than he was selling these torture chambers for. I don't see any of those here. They used to sell the 1and 2g hex ones you see on my windowsill, but those are hard to find now. They came with an UGF, airpump, hood and even a light for $20! What happened to them? They were excellent for bettas or other small fish. Now all I see are small bowls and it then jumps to the 10g tank. The 2 and 5g tanks can only be found in aquarium stores now and they aren't cheap. :-( The all glass 2s (with glass dividers), the 5 and a few of my 10s were left to me by a housemate who moved out of state back in 1988. I will say some of these things are getting a little better. Some have gotten to be a gallon or more and have these mini power filters and some even have mini fluorescent lights above them. Those are ok in a constantly warm house or for somebody in a warm climate. (when talking Bettas that is) But a couple/few ounces of water? Horrible. Koi-Lo.... frugal ponding since 1995...

One should force the stores to hand out pamphlets with each fish giving information on the nitrogen cycle and more..... so the fish have a better chance to survive. Now having laws is a good thing and somebody should do something? Can you see my confusion about your comment. Here somebody SHOULD do something about making laws, and on another thread you used that against somebody. Huh? I have always believed laws should be passed to protect fish, small animals such as hamsters etc. If the store can't get more for the fish then they will go out of business. Without laws we have no way to force our beliefs and humane views on them. Is it fair to them? I'm not sure actually, since some are making it on a shoestring,... little profit. And it would also force people to either spend more or bypass the fish hobby. Many get hooked because of a fishbowl and GF... and move on up the ladder to real tanks and more exotic fish. Those people may be lost to the hobby. So what's fair then? As for the 8 oz ones...that isn't what I'm talking about. They get much smaller than that.

They look like a bowl, but are like 3/4 - 1" deep (front to back). A Betta would have to curl up on it's own body just to turn around.

I can't, but they're out there and people are buying them. It's sick. Have you seen the small betta globes that are desk LAMPS???? You actually screw the betta bowl into the socket holder somehow.

True, but I wonder how common a gravel subtrate is for aquarium fish in the wild, as opposed to mud or larger river stones. Cliff |

Frank Fair enough. ;-) BGA loves a quiet spot, like between the glass and the gravel! The tank with the java fern is fairly low nitrate, so the filter return makes sense. There would also be the most freshly dissolved CO2 there, come to think of it. It's a Flourish Excel tank so atmospheric CO2 is going to be an important carbon source. I'm aware of problems with algae and iron. I'm going pretty low on the iron ferts outdoors right now because nothing is growing very fast. My tapwater tests zero for iron - I'll give the pondwater a test and see if anything has accumulated anyway.
