Yes, but what do you mean by "part"?
Are you running any kind of phosphate media as well?
Do you ever use a turkey baster or small pump to blow detritus off your rocks? Ever vacuum your sand?
Lighting definitely doesn't sound like its too much for shrooms. Are you sure they are 1 watt bulbs? Most DIY fixtures are 3 watts.
Not running any type of phosphate media atm. By part I meant just another little mesh bag of carbon. I dont have any kind of reactor atm
To be honest, I have never used a pump to blow detritus off of the rocks. I thought my CUC would take care of that for me. I do vacuum my sand bed probably every 3 weeks or so.
And the bulbs I'm sure are 1 watt LEDs
