Re: Any Saltwater Aquarium Folks?
crushed coral is by no means the ideal substrate, as you have to vaccum that, you want reef tank grade sand, also hang on back filters (hob filters) are not ideal at all, preferrerly you'll want a sump with a refugium, a sump is under your tank that adds water volume to your tank which is always good, also all your equipment goes down there, a must for a reef tank is a protein skimmer, a good brand is reef octopus, also get a skimmer that is rated for more then the size of your aquarium, refugiums are natural filters, you put a deep sand bed in it along with various species of macro algaes, the most popular is chaetomorphia, it grows very easily and filters the excess nutriuents out of the water very well (the stuff algae feeds on, i rarely have to scrape my glass, also do not use tap water! get an ro/di unit or use ro/di water from your lfs or distilled water, in the long run having your own ro/di unit it best. also a refractometer is way more acurate then a hydrometer, the salinity of your water for a reef tank should be closer to 1.025, 1.020 is way to low for a reef tank
