Can anyone help?
« on: May 11, 2013, 12:41:08 PM »
Im fairly new to Marine, just trying to get an idea of if I'm totally out or ok, and if any advice can be given to get them spot on.

Ammonia 0
Nitrates 4
Ca is on the 520-540 mark
Kh is at 11-11.5
Ph is at 8.2-8.3

I have had it running about 4 months now, is around 160 litres, running a skimmer and have about 20kg's of live rock in there and an argonite bed. I have a pair of saddleback clowns, goby, bunch of hermits, cucmber, a red star, a pair of damsels, a torch coral and a few softies oh and a nice little anenome (the softies and anenome are happy and good) - the torch is quite new, not extending much and I think one of the heads was 'damaged' in transit as its dying back on the one head fairly quick.



They live under a cycled 3x 15w marine blue, 1 15w 20k and one 15 watt 7500k tube (they cycle between the 5 through the day to give a variety of light according to time).

So, for what I have, is there anything majorly off with my parameters - im confused by nitrates being high, i had a problem with diatoms, but 2 days running a cannister with rowacarb, rowaphos, nitrate sponge, ammonia sponge and phos sponge cleared that up perfectly to crystal clear water. I feed only frozen foods (cyclops, brine shrimp, bloodworm, and any of the various marine blocks in the freezer)

nitrates aren't terribly high,but you could run some GFO to help lower them even further,everything else looks OK to me

Hi Doug.
Everyone has diatoms with a new setup, its all part of the cycling process.   In my opinion you should aim to keep nitrate between 0.02 - 1.0  so 4 is indeed on the high side.
Cutting back on your feeding for a couple of days should see it drop, or you could do a water change  but if your over feeding it will soon  reappear.

This is what I test for and this weeks results

Temp: 25c
Salinity: 1.024
Alk: 12.2
Cal: 450
Mag: 1320
Ammonia: 0
Nitrite: 0
Nitrate: 0.5
Phosphate 0.02

It's important to keep the big 3:  Alk / Cal / Mag.  balanced.  Equally Nitrate and phosphate should be carefully monitored if allowed to rise nuisance algae will soon follow.

A good source of information.   http://www.redseafish.com/index.aspx?id=4337

Thanks, so the high Alk and CA are nothing to worry about then? I haven't got a magnesium test yet - them red sea pro kits are a bit on the pricey side... The other half never seems over impressed when I come back from the aquatics centre :/

How long can I get away with 'starving' the tank to get nitrates down? I feel bad not feeding them, they always eat it up, but I have no idea how much food is enough, they usually get a frozen block of food every eve and somedays I pop in two for variety... Is one cube too much?

Hi again Doug.
Just rechecked your stock.

I would drop your feeding to half a frozen cube a day and no more than that. 
Going without a feed for a couple of days will do them good.

The RedSea link I posted was not to recommend their test kits lol, although I do use them but was as a source of information on Reef Chemistry and the importance of having a balanced system.
