How about cycling vs. sand bed
Setup 3 small tanks one BB two SSB and the 3rd DSB then let the tanks cycle and see if it makes a difference using only LR as the variable no live sand. Just test and record your water conditions and plot them out. Also you can photograph and identify any hitchhiker that you get on you live rock. When it’s all done you’ll have enough water sand and LR to put in your 55 and start a tank of you own.
