Thanks for the input.
I already grabbed a whole pile of rock (55lbs of fiji, 35lbs of spiderwick) and live sand (80lbs) and all new filter media for my Eheim 2217 and Rena XP2 filters (good for 100 gal
and 75 gal
respectively) so now I'm just doing the waiting game.
The water quality is looking good so far, nitrate ideal to ok (10ppm)
nitrite safe (almost 0)
ph acceptable (7.8 )
but alkalinity is off the scale... which confuses me since the pH is low for a saltwater tank (should be 8.4 right?)
