Ammonia Troubles

[gotsnow64]

Long story short.....
55Gal FOWLR set up for about 6 months now
4 blue damsels
1 skunk cleaner
1 pygmy flame angel
1 lawnmower blenny
some margarita snails
some blue leg hermits

Water got cloudy after a PWC and ammonia went to 4ppm
added ammolok and after 24hrs ammo was at or above 8ppm
did a 50% water change....
8hrs later ammonia is at or above 8ppm
added some seachem stuff that "eliminates" ammonia and did a 50% water change
2 hrs later ammonia was down to .25ppm
overnight...8hrs ammonia rose back to 8ppm
I dont know what to do anymore

Have you accounted for all of your critters in the tank? (make sure no one is dying and decomposing in there)

your source water or salt mix is bad perhaps?

 

[gotsnow64]

all my critters have been accounted for and so far seem to tolerating the problem....I don't know for how much longer they will continue to tolerate it though. My source water is city water through an RO/DI unit. I have switched from Red Sea to Oceanic salt somewhere in the middle of all this with no difference.

a build up of food then? how is the flow in thew tank? do you have dead spots where detritus can gather?

did a thorough cleaning yesterday and realized I am overfeeding....2 or 3 half eaten forzen food cubes lying around. got all that out and did another pwc with little effect.
