Is my tank suitable for corals?

[aquaruss]

Can anyone tell me what type of corals would do well in my tank?
Was thinking about a pulsing Xenia but was told they grow/spread real fast.

150L tank
Ehiem 2224 canister filter (should I remove all the mediums?)
1x Seio M1100
1x Seio M820
1x Seio M620
250w Metal Halide 10000K
1x Arcadia 42" 38w blue actinic
1x Arcadia 42" 38w Marine white
20kg Live Rock

Water quality:-

SG 1.027
PH 8.4
Ammonia 0.25
Nitrate 0.2
Nitrite 0.05
Alk 5.03
KH 14.1
Calcium 450
Oxygen 7.5

I bought the soft finger coral (below) at the weekend, I was told it's an easy one to look after & it's doing well at the moment. I'm feeding it Salifert Coral food, is this good?

What additional test kits should I be buying?

Thanks for your help :dance2:

No! You shouldn't have any detectable ammonia or nitrites! It doesn't sound like your tank is cycled and the coral probably won't do very well for very long!

Oh..... I see! :thud:

I do find it rather tricky to find the correct colour match with the salifert Amm test kit, can you recommend a better one?

Tank has been up & running with cured rock for 5 months, fish & inverts are happy & all has been good so far :confused:
I'm not sure if it's just me not reading the test results correctly :o

I also do 20L (14%) water changes weekly?

Thanks for helping max

hth and keep us posted it looks good.
p.s. keep an eye on that sea weed I think it's a variety of calupera and most of them can over take your sesile inverts.

Salifert is an excellent line of test kits and pretty much the norm among reefers.

I think I'll test again with salifert,this time I'll do it in daylight, usually only get the chance to test when it's dark due to work commitments.
Salifert do say it should be tested in diffuse daylight.

Thanks all.

Nitrate of .2 is nothing... I think mines around 15 right now and everythings fine (I don't want it there) but in buffalo we lost power for 5days last week and I didn't have a filter on my tank... and was still feeding fish.
