Diatom D1 Filter

Overview
Overall this filter is a great filter to remove that cloudiness from the water. I use it 24/7 which you are not suppose to. Crystal clear water is the only thing to expect when using this filter.

Here is a break down of the rating 1-10, 10 being best.

Filtering : 10
Design: 5
Ease of use: 3
Construction Quality: 5

Positives
TOP NOTCH FILTERING! The is NO filter that can make the water as crystal clear as this filter.

Negatives
Some areas of the filter design I don’t like, such as, back-washing is non-existant when the powder is clogged up. To clean the filter and put new powder in, it is a complete tear down of the filter. The screw on clamp that secures the motor and plumbing to the plasitc jar that houses the media is very hard to get good and tight and allows air to somtimes get into the filter which makes it extremely noisy. Its also very hard after getting it tight, to loosen it. I ran this filter 24/7 on a 30 gallon. The Sand gets clogged up very easy but adding some filter fiber to the intake in the tank help to extend the life of the sand to about 1 month instead of 3-7 days. Your only suppose to run the filter as a polishing filter once a week or so. I thought I should put it to the test. recentlt after about 4 months of running, a seal in the motor went out and started to leak water all over the place while running. Luckily every part that could possibly fail is replacable and you can order from them.
