Thanx seabayaquatic and iammoc!!
I am currently using "Prime" and I haven't noticed a drop in the ammonia.
The method of filtration I have is a wet dry filter! I believe the return pump is rated for 300 or 500 GPH (is this adequate filtration?)! I have tested the PH early this morning (3am) in the DT and it tested between 8.3-8.4 (same as the night.) I have 2 power heads 800 GPH for flow, salinity at 1.025 all other perameters are spot on except the ammonia. I am going to perform a major water change this weekend (27 gallons.) After the water change, my plan is to start building my refugium (30 gallon.) I am hearing a lot of good things about it. Any advice on refugiums please let me know! The guy at the fish store wanted to charge me $800 to build one (are u crazy???) I can build one myself for less than $100. I will take photos of the process so everyone can see! I am convinced that the reason for the ich is because of the ammonia problem.
75 gallon tank (FOWLR) wet dry filter- (rated for a 75g tank), 300w heater+ 1spare, 9w uv, 2x800 gph power heads, protien skimmer rated for 180 gallons, 1/10 hp chiller-(not installed yet) 100 + pounds of fiji live rock.
