各位師兄! 
 
 
I'm going to buy a 28" tank to plant water grass this weekend, (now is 16") can anyone give me advice on which 牌子 of accessories should i buy?
1) 28" tank will buy from "卡x", $260.
2) Light?  As i want to buy a stronger light? PL or FL light is better?  Is 36W x 1 PL light strong enough?  Or if i need to buy 2 lights?  Some shop keepers told me some brand of light do not have legs...
3) Any suggestion for Water Filter, how much for that?  
4) CO2 - i will use my existing DIY CO2 bottle.  I am using an small air stone now.  Can i use $38 type 擴散器 cup?  Will the pressure too high for DIY bottle?
5) Mud.  Shall i use ADA mud.  Am i need to mix with some Sand?  If use ADA mud how much for my 28" Tank?
6) Does a grass tank require 隔屎版 and pump?
Thanks for everyone... i will take all brothers advice before buying the accessories ga la.  唔該晒各位!!!
