FISH DENSITY AND MEDIA

[NYBERWASS]

My first saltwater tank, started about 7 or 8 months ago, is a 250, and my sump holds about another 40. Call it 350. It is fish only. I have one stack of rocks in the center for hiding places, but it's mainly wide open with Caribsea sand. I have eight fish in there. Two large wrasses (about 5 or 6 inches each), one 5 inch hogfish, three juvenile groupers, each under 5 inches, one 7 inch spotted rabbit fish and one sailfin tang. The water only turns over about 4 times per hour, due to limited overflow capacity. Nothing I can do about that. I have at least 20 pounds of marine pure blocks and Siporax media, and plenty of mechanical, which gets cleaned often. When I use my Seachem ammonia test for FREE ammonia, it is always zero, but the total ammonia reading is always very high.
So here is my question: If the cost is not a problem, could I just put another 50 pounds of Siporax in the sump? I ask that because I have no idea if too much media in itself can cause problems. Another possible solution is to use a large pressurized cannister filter filled with Siporax circulating from and to the sump to have the effect of greater flow.

So whadayaAllthink?

Thanks.

Anything that can house beneficial bacteria is never a downside IMO

thank you. I was just wondering about "too much of a good thing."
