Hammer coral and trumpet coral

[polarbear]

So I have a hammer coral and 2 types of trumpet corals. I currently have my hammer coral on the sand bed and my trumpet corals about mid way in the tank. My tank is a standard 90 gallon and I'm running 2x250w 20K MH fixtures. I was wondering where do you guys that run MH fixtures have your hammers and trumpet corals?

Low flow,

I think most people keep them towards the bottom, especially with high intensity light. Sounds like you have them placed well.

Hmm, I ran mine rather high in the tank when I had MH. The trumpets like a lot of light, especially the krytonite variety. Although not a hammer, I've had my Scuba Steve and Pink Tips high and low under MH with no ill affect to the coral. Flow is an issue though, if too much.

The MH that I used was 400, 250, and 150. I'd almost say that you can't get too much light (recognizing that this is not always the case), but fading of the coral is an obvious sign that you aren't getting enough light. I've seen this on the underside of the coral when light isn't penetrating all the way through the main body, or if it's too far from the light source.

I think a general rule of thumb with these kinds of coral is start off low. They are very forgiving should they not get enough light. On the opposite side of the spectrum... I've never been able to give them too much light, or I just haven't tried hard enough.

I run 2 250w MH and had my hammer coral about 24" below the water line (30" deep tank) and it grew from 2 heads to about 8 in a couple of months...trumpet corals, every time I try to keep them they die or just never grow no matter where I place them in the tank...For flow, I just run a big tunze wavebox on my tank so I'd say the hammer and trumpets were in moderate flow

Thanks for the advice. I was only worried as I noticed a part of my hammer coral dieing. I have it on the sand bed in the middle of the tank. I have an MP40 which causes a left to right constant flow on the bottom of the tank. I'm thinking about attaching the hammer coral to a rock on the left side of the tank which is opposite the MP 40

That's what I do. My rocks are scaped to hide my big frogspawn behind the flow, I'm sure they would love next to zero flow.

I've found that if the head is on the sand bed, the head will die. I've always thought that this had something to do with sand ending up in the soft tissue and skeleton.

i have a krypto, hammer and frogspawn, the krypto and hammer are probably mid way down, a 24 in tall tank, also there both right next to a koralia powerheah. At first the hammer didnt seem to like the flow but it has adjusted and growing. krypto seems to like it and keeps splitting heads. I run a 250mh 14k ushio bulb
