![]() "Pszemol" wrote in message ... "swarvegorilla" wrote in message ... Yes, yes I do. contact time is very important. water blasting thru media too fast will not allow bacteria sufficent time to eat nutrients in the water. [...] but biological filtration occurs best slowly delicate colonys building on top of each other forming matts of brown crap charming I know should visit a sewrage farm some time will be quite the bacteria eduaction for you! Sewage farm and aquarium filter have big difference: Sewage is pass through, water passes one time only. Aquarium filter works in closed circuit loop... And this single difference is very important! When you have single pass filter - then yes, you want long contact time for the bacteria to use up all the nutrients from water and leave water pure. When you have closed circuit loop, like in the aquarium, it does not matter really if you put 10 gph through the filter or 100 gph the if not all nutrients will be removed in the first pass, than you have 10 more chances - the same water passes through the filter several times per hour! I would rather say contact time is NOT important. What is important is that bacteria will have enough oxygen in the whole volume of the filter media... When you restrict flow in quest to get long contact time you can make the last part of the filter lack oxygen and bacteria will not work since nitrification requires a lot of oxygen to consume. On the outlet of the filter with low flow bacteria will starve. We do not want this to happen. We would rather give the filter maximum flow it can handle to make sure bacteria in its whole volume of its filtration media is well fed and oxygenated. each filter is matched to flowrate and no, every sewrage farm is not an open system! infact most are closed too! you have missed the point friend and it's too late and my chicky is too hot too explain now. later tho ![]() |

each filter is matched to flowrate How do you measure flowrate for an air driven filter ? How do you check if you reached the "matching" flow ? Where do you get the optimum flowrate for a given air-driven sponge filter ? Is it something written on the box the sponge comes in ? and no, every sewrage farm is not an open system! infact most are closed too! Closed in what sense ? Do you dump raw sewage into the same tank cleaned water is taken out from the system ? Interesting... you have missed the point friend and it's too late and my chicky is too hot too explain now. later tho ![]() There is always another day - sleep well and please explain this when you find some time. |

That would be a killer tank to look and marvel at, but an even bigger killer
to set up and maintain. I set one up for a client end of last year, which was 6'L X 2.5'W X 4'H using 19mm tempered glass for safety reasons. The aquascaping required me to be in the tank ... ok so I'm only 5'6" but it was a lot quicker with me inside and my mate handing me the LR from the outside. Lighting is 3 pieces of 400W XM 15K and 16 pieces of 96W PC actinics and yet its not as bright as I'd like it to be way at the bottom. So the livestock had to be carefully placed on the rock structure, with mostly shrooms at the bottom. Strictly no SPS corals, the rest were mostly softies and LPS, lots of shrimps, and other inverts like cukes and snails. Maintenance is a big PITA on this tank, especially with algae on the tank walls - you can use magnets to scrape off some of it, but the persistent ones need a blade. And finding a blade with a 3-4' long handle strong enuff not to bend was tough. Sure it looks good, but personally, I'd never get this kinda tank for myself wrote in message ps.com... Hi there I'm looking to get back into a marine tank. It's been a while since I have had one. the last was a bio ball setup which i believe has gone out of fashion to be replaced by live rocks etc. anyway my question is.. I'm looking at this tank http://cgi.ebay.com.au/Unique-Custom...arium-full-set up_W0QQitemZ150044026743QQihZ005QQcategoryZ20755QQ rdZ1QQcmdZViewItem and just wondering if higher rather than wider tanks are still harder to maintain with the new techniques of fish and invertebrates keeping. Cheers thanks for taking the tinme to repspond |

I'd also like to just say that as a combo filter they work well but ya sleep n stuff That's one of the many reasons that I like to use one big pump to do all the water movement, instead of power heads. But what ever water movement method you use, with good water movement around the rock and corals, that stuff gets filtered out quite well. Wayne Sallee Wayne's Pets |

It is very hard to compare real ocean to our fish tanks... mate I work with simulations not replications. I know how the rules are different. i.e. size = dilution The only point I wanted to make is that with the proper dedication and research there is no reason a coupla cycled air sponge filters could not support a nice tank of damsels, pair clowns, dottyback, maybe a bicolour angel and lawn mower blenny. I would always like such statements backed up with a nice pictures showing beautiful tanks with no problematic algae running this way :-) How are you progressing in making such photos of your tanks ? Not at all My sponge filtered tanks are chockers with fish. I'm hardly about to go riding around taking photo's of peoples tanks to satify one crazy usenet freek with a million questions and demands. no disrespect intended as I'm one as well but I'm a busy man eh. What are the levels of nitrates and phosphates in your tanks ? WTF would you care? Come on dude What is your maintenance schedule ? I water change 25% EVERY sunday I live beside the unspoilt pacific yea and pump it into big plastic drums on a truck at a boat ramp How often do you play with the tanks ? every day or once a month depends on the tank and it's need for sparkle fresh appearance How big is the tank from the above mentioned example ? get a life mate if you really need to know so much about the tanks come read the bloody journals for them yourself hey If it's going to be a full reef then you need to get serious on your equipment level. chillers and lights need to be bought suppliments to promote coral growth over algae all sorts crap. What supplements would you add ? How do they work in supporting corals to outcompete algae in our tanks? They come in bottles and are called things like 'live rock food', I also mix my own kalk and culture greenwater for me filter feeders when I can be bothered. Remember I work in the industry mate, little widdle fings in your tank like coraline algae and stuff suck minerals outta the water to build body structures yea? Once they are gone the algae that doesn't need them surges ahead. Do your own bloody research. I do not at all see why ya need the details when you supposedly know them dude? If I need a suppliment I ask 4 different reps their opinion, then I ask me fellow lfs brotherhood, then I check my books, then the net and if all else fails or I feel no$taljik usenet ![]() but usually a handful of epsomsalt or calc carb powder can do any job a fancy bottle can do yes I can do the science to a .ppm but when you face a problem the 2nd time, you already have an idea of the solution. 'Display' is a sense of mind. Yes maybe a tank in a hotel is going to have to be 'a slice of the ocean' with no visable filters and exotic corals. but a tank in the living room, stocked with conscienscously chosen fish that do well in captivity, and a bit of maintenence is also what I call a display. What I say by "display" is the tank which has PRIMARY concern: aesthetics. It simply has to LOOK nice. All my tanks look nice even my feeder fish tanks are decorated my goldfish have castles and stuff live plants and stacked rocks getting nicer everyday but looking good hey, sponge filter or no!

Was kiddin mate look fair enuf you are curious and thats cool but really I ain't about to go to huge trouble to 'prove' myself to you tomorrow I drain a cichlid tank and begin to setup another 6x2x2 foot marine display. It will take me a while as kinda moved it ahead a few weeks. still start as early as ya can! I will take a lot of pictures, but be patient mate. Things move slow with these things. If you are curious I will be adding some very boring liverock, substrate, water,and filter media from an established marine tank. My lights won't be ready for a bit but planning on hanging a coupla MH from the roof. The tank is in a new position so going to be interesting to see the chiller power I am going to need to keep this girl happy. Aussie summers hey, already getting record highs for Oct. For filtration I am going with an Otto 450G cannister filter and a few powerheads for water movement. I will upgrade as needed. Yep no sponge air filter! But this tank will be surrounded by others with them! With water changes anyone can keep stuff alive.... although big lights are certainly going to help. So sponge filters- ugly, cheap, basic and give ya the additional challenge of solving alt creep problems, frequent cleanings in aquarium water and hiding them behind something :-) so what I say, they work if you can get past that Now if you still feel the need to educate me, go ahead. It's what I'm here for, but realise I am not your average n00b. and I have dickheads feeling me out all day at work trying to figure out if I know my **** so it may be hard for me to be polite when it happens from a stranger on the net. brown rice 'n all eh |

![]() "Pszemol" wrote in message ... "swarvegorilla" wrote in message u... each filter is matched to flowrate How do you measure flowrate for an air driven filter ? Most are dynamic environs which change as cells clog and flow diverts. I imagine it would be quite the equation. Perhaps contact a filter company pr dude? How do you check if you reached the "matching" flow ? By dosing with ammonia and measuring time taken to convert it all to nitrate Where do you get the optimum flowrate for a given air-driven sponge filter ? a veteren can adjust air taps by eye alone to what is working elsewhere Is it something written on the box the sponge comes in ? yes often it is, however I'm sure a rep can assist you with this as the answer is going to be difficult on paper. you are better practising with them and working out your own optimums. Slighty easier with a few hundred tanks to stuff around with and no, every sewrage farm is not an open system! infact most are closed too! Closed in what sense ? Do you dump raw sewage into the same tank cleaned water is taken out from the system ? Interesting... No friend, you process batches and then dilute. Serious go on a tour, you will get some good ideas. Almost every filter in the hobby was developed from the sewrage industry. Wheels and ugf and all sorts of stuff I can see your interested and I can only say READ READ READ man!! you have missed the point friend and it's too late and my chicky is too hot too explain now. later tho ![]() There is always another day - sleep well and please explain this when you find some time. no prob mate, but perhaps a few less broad demands and maybe I will bother explaining anything more than half arsed |
