Okay 2 to 3 days ago everything was fine, normal tank. First sign something was up was my tank got cloudy for about a day, fish seemed lethargic and unwilling to eat. I ran my test and right away I noticed The Ammonia was as high as the test could read, I didn't believe it so I checked my other tanks and the Ammonia was 0ppm on those. So last night I used the half bag of salt I had left and did a 50% water change plus I opened both canister filters and changed the Purigen and The Fluval clearmax pack plus added new carbon. This morning I checked it again still pegged at 8.0 so I added the max dose of prime...Surprise no affect. Now this is not a reef tank, it's I grow and displace different Macroalgae's being in Florida shipping and selection are great. I do not think it's the algae I mean it has been in there awhile. I just ordered more salt from amazon (we have no local fish store} Does anyone have any ideas or a way to slightly reduce this crazy high ammonia. As you can see in the pics most of my fish are hiding which is very much not normal for them. I pray this tank doesn't crash soon
