Water Movement For LPS...

[Archilles19]

I have a few hard corals in my tanks consisting of torches, octo...well....mostly....

I'm using 2 Tunze6080 for circulation & the return pump capacity is 6000 ltr/hr (of course at 0 head lah)

The problem is...when the MH turns on....the torches will expand fully & sway to the surge of the water....the pumps are not directed directly toward any of the corals but the direction of point causes the water movement in surge pattern....meaning....the torches tentacles will sway left then right slowly most of the time then at certain interval it will sway slightly vigorous due to the surge.....well thats for the torch corals

But the octo that I placed nearby, which place have the same surge pattern, does not seem to want to open fully....of course the torch & octo tentacles does not touch each other lah.....

I dopubt theres anything wrong with the water because my torch, clams will open fully during the MH time.....& water parameter is all okay leh

Does the octo require a more quiet place....like the sun coral...of course with adequate lighting lah.....

Anyone..???........

Hi Achilles19,

I am not an expert but this is what I would do. Place the octo in a quieter spot first and observe. If its a new specimen, it might be sick or not adapting to your tank environment. Keep it quiet for a few days until the tentacles come out, then see if it requires more flow. The previous LPSs I had did not appreciate tunzes- the flesh would be stretched out to near tearing. But yours might be a different situation.

Hope this helps.

i used to have torch. from i little experience, i find that torch will appreciate higher flow,compare to octo. octo need quiter place or their tenticals will extand very long ,not nice. and new octo do take some times to get use the tank. my coto don open fully in the begining, and after a week or so, it expand like no body buiness.

hope this will help ohh ya, i think sun need moderate flow too.

yeah, i experience similar.

interesting. I would like to have both of them again as they are in the office tank now.

i got both octo and frogspawn and after a series of different placement, i find that if u put them in generally higher flow than needed, they were be extended till quite high and can be unsightly. if under low flow, they will look just great..

If tyhe octo does not open fully, it means the flow is too great for it liao... better to change to another spot...

Think the best idea is to switch to lower flow area to check it out first. Cos LPS generally dun need that much current
