Have ask the shopowner who i bought it from, said it's the power unit problem. And to fix it would cost me $50! Half of the heater price. ...I decide not to buy from then next time, never! Fine, I threw it and bought a 36 watt, $84 from the link you give, larain. Thank you both.

thanks, Gouldian. As you said, LED is now more widespread, am i right? in fact i am looking for a aquarium light. if Led is better, what kind of led aquarlight is the most popular? sometimes the prices is largely different. i've narrowed it in two types, 156w Fluorescent T5 LED Aquarium Light Reef Lamp & 216 LED Grow Light for Plant & Coral Aquarium Blue Red no doubt that the expensive one is better but does it do anything better for the fish than the cheap one? or just because it looks nice and consume less electricity?

what's the features of LED and PL lamps, what's the difference between them? stupid questions again, forgive me...

well, i've heard about that. But one of my friends recommends this website, she bought some little staffs from it and likes them very much, i guess it may be kind of reputable online shop, and the price seems not bad.

okey, i'll try this. thank you very much !

what is a "cheap china brand"? but the one i post is not a chinese product. okey, i will consider a hydro nano wavemaker. thanks!

it's 30cm*60cm.

thanks for your suggestion! the coral i am intending to keep is yellow tip torch coral. considering your advice, i think a 800 gph wave maker may fit, right? just like this one? http://www.thelashop.com/catalog/Wave-Make...-gal-p-671.html

i started keeping fish recently, all i have done is buying a 20 gallons tank, saltwater coral and reef, and i 've also purchased a metal halide HQI Light from www.thelashop.com the last step is to install a wave revitalize the tank. the question is, do this kind of wave makers work in any aquarium tank? http://www.yescomusa.com/product.php?produ...t=61&page=1 Could somebody give me an answer? Many thanks!
