CLS meaning closed loop system am i right?
i don't really know what deciphers a closed loop system... is it b.c our return line ends at one point and not all the way back around? so far i like it, i used both number 1 and number 2 ball valves to adjust the flow( the third ball valve isnt necessary because we don't have much flow going to the 4th inlet into the tank as is). we are getting good flow back into the tank, so i think its working well. still just the first week but everything is running smoothly.
what should i do about run time of UV, skimmer, and lights? i also have 3 1 watt blue lunar rights... should i set those up now and run those all night or is there still to much oxygen in the sand...tanks been up since saturday the 27th
again, thanks for all of ur comments and advice. ill get some pics up of the tank to show u the 73 pounds of rock we got
