Still showing ammonia? Mad

As I posted on your other thread several weeks ago, you should certainly not be seeing any ammonia (or nitrite) in a one year system. Sounds like something is fundamentally out of order with your filtration, did you figure out what caused your sump to crash and/or stagnate... what is your system turnover rate...

Try making a series of water changes, you need to get rid of that ammonia, and pronto.

so yes I did figure it out witht the sump ithink. I had a lot of waste, from what it smelled like. in the bottom of the sump. just cleaned out the sump.


how many water changes should I do do u think? maybe I should have two powerheads instead of one? and filtration. I have a micron bag, anything else I could use?

OK, for the sake of really having fun, I'm going to stir up some controversy. Here goes...

Lets talk sand! Your sand bed depth is a nightmare. I have found best results when I stick with opposite extremes. Less than 1'' is fine... very little nutrient accumulation. Between 4'' and 6'' is great, you should receive good denitrification from these systems, assuming you are not using a plenum or screen dividers, etc.

Unfortunately you have the exact wrong amount of sand. Sand kept between 1'' and 4'' depth does not generally provide effective denitrification and actually can release nutrients back into the water. I am wondering if this is part of your problem. If it is, the solution might be as simple as removing your sand bed with a syphon and giving the bottom of the aquarium a good cleaning of detritus accumulation.

Otherwise, your readings have no relationship. Nothing about these numbers you are providing sounds typical of any marine system. I am also curious about past chemical additions to your tank. I think the recommendation of Kent Marine Super Buffer DKH suggests a very poor understanding by the LFS of the alkalinity and calcium relationships, which makes me question prior advice you may have received. Your problem could lie in a decision you made 6 months ago that just now has compounded to a breaking point.

I need more history and details.

so mark I'm thinkin u may be right abou the sand. my other LFS said the same thing. the only problem is, will the rock break the glass without cushion from the sand? and as for the history of the tank. I've always done twice a month water changes. I've always use the two part buffer system. I've use phytoplex for about six months. I just strated using some kent marine additives. not sure the name but its a blue colored label. but I'm not quite sure about what u want to know. no history of bad algae problems. let me know what u need to know if this does not help.

The frustrating part about marine systems is that "I've always done it this way" does not mean that you were doing the right thing. So many problems occur as a result of long term methods that work for 18 to 24 months and then one day the system crashes. The sand bed is a perfect example of this.

Many reef hobbyists run their systems bare bottom. I personally use both methods, with 4'' of sand in my 58 bowfront and just under 1'' of sand in my 180. I had no difficulty at all in getting my rock to remain stable in the 180 using the lesser sand depth.

Not sure how else I can help at this point. I would continue with the regular water changes and monitoring. Keep posting updates. And remove some sand, in my opinion.

Plenty of people run bare-bottomed tanks and have no problems with rock stability. Wink
No worries.

I'm not so much worried about the stability. I'm worried about too much pressure on the glass and it breaking

Heh... that glass is stronger than you think. The pressure exerted by water weight far, far exceeds the weight of the rock you're going to add. As I mentioned before, lots of people keep bare-bottomed tanks with no problems. I've seen some really beautiful monster-sized tanks that are bare-bottomed.
