How can I make an infrared light filter?
I am working on an infrared circuit. I notice that the IR phototransistor is sensitive to all light (including infrared). How can I make a filter that blocks all light out except for infrared? I have heard you can go into Walgreen's and get them to develope a blank film roll. Is this true?
i was once told that exposed developed film made a good IR filter but i expect youd need a couple or more thicknesses
just had another thought what about finding an old tv remote and using the led cover off the end of it?

Choose the Pool Filter That is Right for Your Pool
Pool filters are essential to maintaining your pools crystal clear look and clean and germ free feel. Don’t allow your swimming pool to become a hotbed of germs and bacteria – which can happen with all those bodies jumping in and out all day. Pool filters keep your water from going septic and stops swimmers from getting sick as impurities are filtered out thanks to the pool filter. If you didn’t have a pool filter and you left your pool alone it would turn green and algae would start to form. Catch the germs when you can’t see them by installing a quality pool filter that will suit your pool.
There a variety of pool filters on the market so be informed before making your decision. Three popular types of pool filters include Sand Filters, DE Filters and Cartridge Filters. Below is some information on each of these types of pool filters:
Sand Filters: Pool filter Sand are very popular at the moment as they are a basic pool filter option for ensuring bacteria is being cleaned from the pool water. The way the sand pool filters work is that dirty water is pushed into the filter where it is filtered through sand. The dirty water sits on top whilst the clean water is pushed back into the pull. When the pool filter is full with dirty water it alerts the pool pump which then flushes out the dirt and grime away from your nice clean water. Most companies will sell pool filters and pool pumps together.
DE Filters: DE (Diatomaceous Earth) pool filters use crushed fossil or coral like substances instead of sand. This substance is often finer than sand and DE pool filters are more complex filtering systems which is why they produce the cleanest water. The downside is that the filters need replacing more often, which makes this type of pool filter fiddlier to use.
Cartridge Filters: Cartridge pool filters are a third option for pool owners. This type of pool filter collects dirt and debris via a system of removable cartridges which can be easily removed and cleaned. They do require more manual maintenance and are suitable for smaller areas.
Remember that whatever type of pool filter you choose for your pool you need to keep it clean so that it continues to work for you and keep your pool clean and clear of nasty bugs. Regularly check the filter for any buildup of debris including leaves, dirt or hair.
