Hi, I have recently read an article in the "Aqua-Zone" magazine about "反方向底喉架". It's advised in the article that this "反方向底喉架" is better than the traditional "底喉架". Is this true? Anyone is using this method? Also, it is suggested to put a filtering cotton at the hole of the pump where the water is sucking in order to avoid pollutants being accumulated in the bottom of 底喉架. But can anyone advise how can I fix the cotton in my pump? Is there anyone who can take a picture and show it to me if you're using 反方向底喉架? Thanks very much.
