Polyp extension

[Eniram]

Guys does high levels of MG bring up good polyp extensions?

If not what will bring up good polyps extensions other then lights and flow.

Share your experience

i'm currently boosting my mg from 1300 to 1600. pe has remained constant so far

Low phosphate levels will bring about good polyp extension. By looking at PE alone one can gauge the level of PO4 in their system.

Just my 2 cents!

O yar there is one more product if u are looking for a short term immediate polyp extension. Zeovit coral vitalizer. The best product out there for short term sps polyp extension.

When I dose Iodine I also see polyp extending slightly more.

Both of these are short term extension though. Great for house visits. Just dose before ur guest arrive!

feed your sps like oyster eggs....u will get polyp extension...low po4 plus lots of food floating around

Yo Jeremy. For me.. It'll be KH.

I observed that occasionally when my kh drops below 7, the polyps are usually not fully extended.

So now my lime green Millie is my visual kh "test kit"..

Thanks for the input guys. Lots of various methods to boost PE.

Foods / Feeding

Acropora Coral Feeding: In the wild, Acropora corals have developed several feeding strategies. Through a symbiotic relationship with a marine algae, known as zooxanthellae, they receive the majority of their nutrients. They also capture planktonic organisms and microscopic food particles from the water column and can absorb dissolved organic matter.

In captivity, feeding zooplankton once a week is the preferred choice. Copepods, Artemia, and nauplii are too large for them to ingest. But new forms of prey are being developed including invertebrate larvae and new strains of rotifers. Many feel that Acros in captivity need to be in a tank that has dissolved or solid organic matter to survive and thrive. Without this, they may seem fine for a while, but over a few months, without any visible indication, they may end up dead because of starvation. Signs of lack of food would be no new growth, polyps extending and some tissue recession.

Aquarium Care

Excellent and stable tank conditions are required to keep all Acropora spp. corals. Doing water changes of 10% every 2 weeks is needed, although it is suggested that doing 5% water changes once a week will bring about amazing results. Keep the nitrate levels low. Tanks should offer high calcium levels and strontium should be added. Suggested levels for Acropora species are:

•Calcium: 400 to 450 ppm (closer to 450). If the Acro does not have enough calcium, it will not grow. There will be no tissue recession, but the polyps will be extended.

•Alkalinity: 3.2 TO 4.5 MEQ/L (8 to 10 dKh - 10 is recommended)

•Phosphates: 0, zero. Phosphates are the worst of all and all corals hate them.

•Magnesium: 1350-1500. Magnesium makes calcium available, so if your calcium is low, check your magnesium levels before adding any more calcium.

•Strontium: 10
