oh Thank you so much for the help,Tank has been running since last 5 months now,Though it is really looking very dirty. i m keeping the back glass untouched. i also have this huge dead coral this ditom is also covering all that. i have some snails very small they born by themselfe(i dont know how).. they clean a lil bit. but i should not worry about this???
also i needed to ask how to control temrature.. i cant afford chiller and the weather here goes wild in summers minimum is 33 C. i use to frezee plastic botels filed with water for my goldfish..any other way?
