noob here - sorry for my ignorance - i have a well established 55 gallon tank - but my lighting is woefully inadequate - i do grow water sprite albeit slowly - hahahahaahaha - anyway - i need a good lighting fixture for my setup that wont break the bank - any suggestions ? i really want to grow java fern and water sprite - many years ago - i once had tremendous success with java fern - and water sprite - my tank has 2 marineland hang on the back waterfall type filters - 2 large plecos , 4 pictus cats , and 2 angelfish - i use the water sprite as my guide to water quality - so - any suggestions ? right now all i have is a 40 watt grow light on it - i probably need at least 200 watts - right ? thanks !
