I have two questions.
first I am in the process of setting up my 75 gal
., so I set up a twenty gallon w/ live sand from the beach, a power head, canister filter and heater. I has been going for about a week. no fish yet, but there seems to be ammonia from the sand. is this okay, also there seems to be this brown muck covering about half the sand bed. is this normal
I am setting up a thirty gal
. at work. what should I need. just a bottem of the line salt. tank. I was thinking of using a lexan cover, a regular normal output light, a reverse flow undergravel filter, heater. is this good enough and with the under gravel can I use sand or do I have to use gravel. what should I use for rock, remember cheep. is the filtration and circulation good enough thanks.
