In a fowlr
you would test the same things as fw
, except of r the salinity. Once you start up a decent coral population you would have to start testing for calcium, magnesium, alkalinuity and phosphates.
The main difference in the fowlr
vs. the corals is the lights and the salinity. FOWLR
can get away with about 1.021-1.024 while a full reef it is suggested keeping the salinity at 1.025 which is pretty close to natural seawater at 1.026.
Also with corals you need better than average water parameters like nitrates.
