It was too advanced for me as far as it was quite detailed on how things worked, but I couldnt find any use for that information. It isnt like a DIY book or something, perhaps I am just too stupid to appreciate it .
Wonderful book. Very pertinent for anyone in this hobby. Some of the concepts seem to be at odds with reef keeping practices - like flow rate. Escobal seems to promote low turnover rates in tanks - 2x/day to ensure near 100% flow through equipment like skimmers, etc. Very helpful when plumbing tank. Makes you think before putting 15 elbos in your pvc plumbing.
