I have a standard 6' long 125 gallon with a 4' 6 bulb ATI Sunpower T5 centered 12" over top. I bought a huge order of Ricordea so I can hopefully make an make an epic garden. For flow I have two WP-40s, one on each end. Here are my questions. Is that going to be too much light for them if I put them on the ends? Should I make a rubble pile to place them on or should I put them on the sand bed? How much flow can they tolerate and still be "happy"?
