Whats Wrong

[pluff]

:help: Ok everyone i bought a 90 gallon FOWLR and a couple feather dusters,with 2 large Maroon clowns,and 2 damsels,on saturday.I used 90% of the water with the transfer.Trust me this tank was dirty.I even hooked up extra filters to help clear up the mess and on sunday i did a 25 gallon water change.here were my test.
Salt = 1.022
PH = 8.3
Ammonia = 0
Nitrite = 0.3
Nitrate = 10
Temp = 78
So on Monday i decide to do another water change to clear up some of the scum,i also did a 25gallon water change.then i hooked up a UV sterlizer,as this tank is full of algea on the back and sides big time,like i said this guy never took care of this tank.So today (tuesday)i tested the perimeters again and here are the results
Salt = 1.022
PH = 8.3
Ammonia = 0
Nitrite = 0.3
Nitrate = 50
Temp = 80
Why is my Nitrate so high?is the tank going throught another cycle?I'm gonna do another 25gallon water change,or should i wait?
Thanks

If there was a lot of algea it was probably the nutrient export (read nitrate export). Now that you are trying to get rid of it, and some of it probably died of in the move there isn't as good of an export system. The only way to remedy this is to put in place some sort of nitrate export system. This could be in the form of a DSB, or it could be in the form of some calurpa, such as grape carlupra. It is fast growing, so it would probably help. If you decide to go with a DSB just make a trip to the nearest HD in the states and get some of their south down sand. Before you go out and buy carlurpa, let me know how much it is where you are at. If it is cheaper to ship it, and if it will ship well, then i could send you some. i got enough of it to spare some at the moment.

What kind of substrate is in there now? It could of been stirred up during and after the move which is affecting your readings. If this tank was a bit on the neglected side there could be a ton of crap trapped in the c/c. Try to vacuum it out as much as you can, say once a week for the next couple of weeks. Also make sure your make up water isn't adding any nitrates as well.

I would suggest not vaccuming. When you do this you will end up sucking out some of the good orginisims such as worms, pods, stars etc.

Scott, in most cases I would wholeheartedly agree, but in this case I really doubt that there are much in the way of beneficial critters in there to begin with. I guess Pluff can only answer if there is any life in the live sand, and if there is vacuuming would be a mistake.

I havn't noticed any critters at all.
