Removing Algae for dripheads

Algae is good for the plants, but very bad for the emitters so that is the dilemma. So it is a matter of balancing the filtering. Algae can be as small as .5 micron. The smaller stuff in algae is bacteria and beneficial to plants. A filter is recommended with every drip irrigation system because it removes sediment and other particles that are large enough to clog the emitters. Most tape and drip emitters can not handle up to anything large than this. So at least a 200 mesh filter MUST be used on any T-Tape system. There are, of course, smaller micron filters (i.e. a 200 mesh equals a 73 micron filter) that will take out much more. However, these are generally used in drinking water systems and not irrigation systems. Most irrigation filters you get will be this matter out without a problem.
