nitrate

I like to use 5500 or 6500k daylight bulbs. Do you have bio balls? Do you have any sponges or filter socks or felt filter pads. How much do you feed? What kind of substrate do you have in your DT? Luna

 

i took all the bio bals out and replaced with live rock no socks of felt anywhere except out let from skimmer i feed 1 cube of frozen food 2x a day plus some dried seaweed 1 x a day i have live sand in my d/t
sparti thanks for ur help afk now bed time for me

 

How long ago did you clean/replace

canister filter no sponge in it, just full of kent nitrate sponge.

Good Luck, Larry

 

That's a lot of food. I saw your tank and it looked like you have the file fish, sail fin tang, the lemon peel angel?, black clown and a yellow tailed damsel. I feed about 1/4-1/5 of a cube every other day, see my signature to see what I have. Two cubes a day is a lot of food and that is probably where your nitrates are coming from. Your phosphates may also be high, I don't remember seeing a test result for that.

On a side note, mangroves take out a lot of Mg from the water, so if you don't have a test kit for Mg, get one and dose accordingly.

 

I feed two cubes a day and my Po4 and No3 are at zero. Feeding isnt the problem, filtering the water is. Luna

 

Not saying this is wrong... maybe you have a better clean up crew than sparticus for eating any left over food? Just a thought. :-/

Good luck.

 

Its not so much the clean up crew, even thou they do help. Its how well your system is able to export Po4 and No3. Luna

 

very little food hits the deck guys these babys hoover it up fast.
@ shipbear i added the kent nitrate sponge about two months ago and i clean out every week. i have only just, about two weeks ago, removed the matieral filters in there the sponge and cloth, as i read somwhere on here they are a nitrate trap.
do u think it might help if i took out the kent nitrate sponge and replaced it with broken up live rock it might help ?
@ lunatik
i will replace the bulbs as u have suggested tommorow.
thank you all for the help and advise

 

i have ordered some bulbs 2 x 18 watt tubes they tell me they are daylight tubes and there 6500k hope this is correct soon find out i guess

 

So hows your tank doing now..? Did the nitrates come down..
Mine jumps up now and then.. But I tend to over feed..
Keep us posted..
