How Do You Cylcle An Lfs

Ok here is the official answer. The Maidenhead Aquatics system has been developed over 27 years with constant experimentation and improvements taking place. Depending as to the age of the system the setup will vary. Systems more than four years old are generally filtered with sand filters and trickle filters. Newer systems are generally filtered with bubble beads and these provide biological and mechanical filtration in one unit. All systems are fitted with large banks of uv's. Many systems will also have ozonisers and marine systems will commonly have denitrifiers.

Maturing bubble bead filters can take a very long time and so the store at Farnam has add large pond filters to the system as well. Filter bacteria actually life within the biofloc which attaches itself to filter media, rather than on the media itself. When bubble bead filters are back-washed much of this floc is lost and this is why they take a long time to mature. However once mature they give excellent clarity and water quality. The pond filters mature much faster and will remain on the system until the manager is completely happy that the bubble bead will cope by itself. In the case of Farnam Nitra-spira was added to the system to speed maturation.

Water changing the system is very simple. By turning a few valves and flicking a few switches the water flow from the filter is reversed and the dirty water is flushed to waste. In order to maintain water quality (low nitrates) daily water changes are required. The volume of water changed will vary from system to system depending on system age, stocking density and local water quality. The majority of our stores will dechlorinate there water as it is automatically topped up. Some use chemicals like aquaplus and some use in-line dechlorinators. Many of are systems are soft water provided from large 650gpd RO units and these do not require dechlorination as the carbon pre-filter on the RO unit does this in order to protect the membrane.

If you would like to know more about your local shops filtration system, please ask the staff in store.

Don't know about how LFS cycle their tanks but when I am not messing around with tanks I teach philosophy and there is a lot written on whether you need language in order to think and the way the debate has been going for a long time now is that you do. Everything is instinctive or responding to behavioural cues until you start to build on that with language (sign language counts of course). And if you don't start learning language as a child it gets harder and harder to do and most cases where this has happend, wild children bought up by animals etc., they never really acquire full language skills. Not my specialist area but it is interesting.

Babies need to hear the sounds associated with their language whilst they are still young else the brain doesn't think it needs that part of the brain and discards it. When we are born we have the networks required to speak every language, however as we here our mother tongue only all the parts associated with other languages become weaker and die back. This is partly why it's so difficult to learn languages. I think this happens within the first 6 months but this isn't my area so don't quote me on it.

I do know that babies can communicate thoughts before they can vocalise them as children who are taught sign language from a young age often begin communicating much earlier. So as long as they are still hearing spoken language around them it can actually aid the speed at which they learn to communicate verbally.

It's all very interesting stuff and I just wish I had the time to investigate it further

I don't have kids so I'll just Hypo this one . I think kids associate crying 'cos it gets attention (cause and effect). They cry, mom comes and checks on them (like an oven beeping). Now if the child is "Deaf" and can not hear themselves crying then this would be interesting. I have a friend who has a deaf cat (male black and white with blue eyes without a third color it will most likely be deaf . Ain't Genetics fun?) he'd meow on and on and not know he's meowing. I don't think babies could write a novel since all they have in their soft head is the basics (even that's a stretch). I know babies see shapes but they can't understand what it is (like those weird red, white and black toys). Emotion I think is learned not born with (it would be cool to know a twin situation where one was a serial killer and the other a rocket sceintist).

As for language it's like that old saying "If you don't pull it out and use it, it's going to rust" rings true. I didn't speak a lick of English when I arrived in the U.S. nor did my father. My fear was I would forget Japanese and not learn English so in effect I'd be screwed. But I learned English and forgot Japanese (enough to get food, drink and get my face slapped but little else). I used to think in Japanese but unless I think about it now I'd be thinking in English automatically. Now my father never really learned English since he worked in a Japanese owned company and just got by on Pigeon (as in Broken Jap-English). Since, he didn't have to deal with it he never bothered. Situations were different for both of us I was in "swim or sink" and he was not. I also think children can adapt better since they don't have hang-ups or set in their ways.
