I'm in the process of setting up a new 40" FOT equipped with tailor-made filter （滴漏）. I also plan to add some sands to the bottom of my tank for decoration purpose. Do you think that it's necessary to install the undergravel filter at the bottom of the tank? Is it okay not to install this filter if I'm not going to add too much sands to the tank? Please advise. Many thanks.

如果要用UGF咁用reverse UGF會好d喎.. 吸水口有機械式過濾..

Thanks but I have never heard of reverse UGF before. Do you have a picture for this type of UGF? Also, how much is it? For a 40" tank, what kind of reverse UGF should I buy? Please advise.n Many thanks

其實同UGF差唔多... 只係個泵唔係抽底喉架... 係吹底喉架... 泵吸水口有機械式過濾.. 咁吹入底喉內既水就會冇屎..
