0.5 Micron Replacement Filter

Comments: I started a new 125 gallon tank in early December 2012 that utilizes a Coast to Coast silent overflow system and needed filter socks. I use the 0.5 micron socks I purchased from MD on the primary and secondary drain lines as the primary physical filter elements. I have two sets of socks and switch them out twice a week. I rinse the used socks with tap water, ring them and set them in the sun to dry. This rids my tank of unwanted fish waste and uneaten food making it easy to control nitrites and nitrate levels. The filter socks are inexpensive and easy to use and I would recommend giving them a try.

Comments: I use both the 0.5 Micron Sediment Filter and the 0.5 Micron Carbon Block. These two in combination do a great job of filtering the water. I recommend these filters for anyone wanting to filter water.

Comments: I purchased this Sediment Filter to replace my aging one. This fit my RO/DI unit perfectly even though it is not one of the brands listed. Works well, TDS back to 0.

Comments: Was initially going with the 1.0 micron for cost savings but decided to stick with Spectrapure recommendation of 0.5, a little more but fish are a whole lot more. Perfect fit no replacement issues.

Comments: I have used this in my RO/DI unit several times. This has consistently performed well. I like this much better than the 1.0 micron filter because it seems to help the other components last much longer.
