I've been debating for quite a while, is that a picture/painting or a really nice public aquarium?

great page.

Great info.

My clam is in the bpottom corner of our 180.
the lighting is 1600 watts of 20k, metal halides.
The clam has grown quite large since we aquired it from a x-reefer.

So any one of these clams will survive in my tank?
Lighting: power compact 65W 50/50
Depth: 9"

In this condition, will it be fine to place the clam up on the highest point of my live rock(that will be 3" right under the lighting)?

I would not attempt to keep any Maxima or Crocea under that lighting chjy69, and a tank that is only 9" deep will not house one of the other larger, less lighting needy clams.

Alright, well you didn't say your tank was only 9" deep, (typo).
Honestly, one of the larger less lighting needy clams will quickly outgrow a 20 gallon, and quickly soak up nutrients such as calcium.
If you really want to try it, get a 150 watt HQI, look into either a viper k2 clamp lamp, by JBJ. Or a pendant, such as the outerorbit with luner lights.

How about a Current Nova T5? Could I keep a crocea 3" away from that successfully in a 20 gallon standard??

ezcompany · #60 10/07/2007, 07:38 PM

it should be fine. novas aren't single reflectors though but still put out more light than regular pcs.

First question, is this a crocea?

Second question, is this a good position:

(mid-right next to leather)

Its a 150 watt sunpod MH light. 20 gallon tank. I feed phyto once every 3 days.

ezcompany · #62 11/26/2007, 12:42 PM

1. Yes it is most likely a crocea.
2. Yes that is the perfect spot because a.) they are rock boring clams and b.) good light in that spot

Tank looks relatively new. do you have a calcium / alk dosing regimen?

Musho3210 · #63 11/26/2007, 05:29 PM

tank is 5 1/2 months old, weekly water changes. Calcium and alk hasnt been a problem yet so i dont have a dosing regimen.

ezcompany · #64 11/27/2007, 08:15 PM

If you plan to add more stony corals and clams, you will need a dosing regimen for your nano. phyto is not necessary for the health of your clam. as long as you are feeding your corals/fish, it should get enough nutrients for its needs.

Musho3210 · #65 11/28/2007, 06:08 PM

Well i already have a jar of phyto from a while ago, hate to see it go to waste so i might as well feed it...

Clams arent as picky as some people make them out to be.

The rule of thumb was always "needs lots of light" because they are usually kept in tanks with halides, yes. But often, they are on the sand anyways, and years ago when that standpoint was developed, sure, it took alot of watts to get the light needed.

Now we have better reflectors, more efficient bulbs (and in many bluer colors), and better ballasts. Yet we still think they need alot.

Okay, so I have been doing PAR readings of clams for a while now in fellow reefers tanks. I found that a vast majority of maximas and croceas are in only 100-130 MicroMol/m2/s intensity light, and doing awesome.

Can they take more? Of course. But do they need it?... no. Sure, they were kept in tanks with high-intensity, but that doesnt mean they are kept themselves in that high intensity light. They are often in the sand. Considering how crappy reflectors were 6-10 years ago in this hobby, I would imagine it would take alot of light to get that 100-130 down on the sand. Now though... its easy. T5s can easily do that.
