smidey Posted January 10, 2012 Report Share Posted January 10, 2012 Sure, bacteria will be there ...just not the ones you desire. The fact that you do observe any gas pockets indicate that you have significant populations of anaerobic bacteria present ... And in pre-filter days as in China 700AD, they did frequent water changes to keep the fish alive. i haven't actually observed any, just being cautious i regularly start small tanks for fry and put the fry in immediately. I use a new filter, water and substrate from an established tank and have never had any issues, the only times i have had issues was when i didn't put any substrate in. I don't know the sciences of it, just know what my experiences have been. we can get info from books etc that state "X" but if you have had "Y" experience regularly then you have to learn from that.

smidey Posted January 10, 2012 Report Share Posted January 10, 2012 cool cheers smidey just check out your tang tank on youtube what an awesome tank next project tangs for me thanks. i'm not that happy with the vid, the colours are all over the place and it looks a lot better in person.

My take on this is that the bioload is so small in this situation that the biological filter on the substrate is able to cope. However, the biological filter is primarily in the filter media of what ever filter you use. Quote Link to comment Share on other sites More sharing options...

You could stick some substrate in the filter so it can easily expand to the filter media? Quote Link to comment Share on other sites More sharing options...
smidey Posted January 10, 2012 Report Share Posted January 10, 2012 i'm not convinced a 7L bucket with what ever in it can be better that 0.9m2 of tank bottom covered in substrate for harbouring good bacteria. each to their own. it certainly would be interesting to get a hard-fast fact to it.

Squirt Posted January 10, 2012 Report Share Posted January 10, 2012 Well let's assume that each bio ring has a total surface area of 5cm^2 and .9m^2=9000cm^2. Therefore you need 1800 bio rings to equal the amount of surface area. Or if we take some information from a trademe auction that has 1500cm^2 of surface area per 1L of noodles. Then 6L of bio noodles is equiviliant to the surface of you're tank Quote Link to comment Share on other sites More sharing options...

Then 6L of bio noodles is equiviliant to the surface of you're tank and when you time the surface area of the bottom of my tank by the thickness of the substrate and multiply that by the surface area of each chip..... that will be a big number. if we take bio rings in a canister, there is a cup full i guess in my CF canister. there must be a hundred of cup of bio rings to cover the base of the tank.

As far as I can tell you're suggesting that an undergravel filter but without the flow of an undergravel filter has more biofiltration capacity than your appropriately sized take your pick external filter?? The issue I see is that although you have a large surface area, it's not functional in that if you create sufficient flow, your fry will get battered and then fried! :slfg: http://www.americanaquariumproducts.com/Aquarium_Filtration.html Quote Link to comment Share on other sites More sharing options...
smidey Posted January 10, 2012 Report Share Posted January 10, 2012 you can think what you like, just as i do. from my experience, i believe the substrate to be very beneficial for keeping the water conditions good. maybe my fry won't survive, i only have over 300 of one species that have survived with very few losses so what would i know? :lol: what i do has worked perfectly so far so i won't be changing anything.
