Acropora Propogation Tips

Postby Adam007 » Fri 15 May, 2009 11:25 am

What are some handy tips you have for propagating Acropora ?

The only one I can think of is with the frag plugs, give the top of the plug a good scrape with a pocket knife or similar to remove the rough surface, seems to let the frags attach a bit more easier!

When mounting frags, horizontal is better than vertical. You'll find they encrust quicker, and more polyps will convert to become axial corallites (growth tips), and lead to faster branching and growth.
If mounted vertically, at least to start with until it gets a move on, you'll only have the one growth tip.

I use white marble blocks that I got from the local headstone manufacturers as "frag blocks".

They charged me $20 for a bag full as they were just going to throw them away.
As they are pure calcium carbonate (same as what acro's are made of) they are perfect for the purpose.

They were happy to cut them in to the size I want (8cm x 5cm) and the good thing is they are nice and heavy and dont get pushed around by my pumps.

Go to any Monumental Works - you know the places
that make headstones for cemetries.

I would recommend you go for pure white.

great Idea, or you could get lots of them and sell them? I would be happy to pay you for a few

I also like to make frag plugs using pool dust and some super glue. Same effect as the white marble blocks but you can put them in an egg crate rack.

The Eric Borneman vid had lots of good propagation tips.

Great thread.

I use the coral cradles (PVC) that slot into eggcrate.
39cents each from Ausfrags.
I prefer to use a small blob of selley's Aquakneadit to attach the frags, sometimes, as a second resort superglue.

firstly, i cut all my frags into a small bucket of tank water, then i make sure all the frags have a flat base, and making sure all frags are growth tips, of at least one inch of length, for maximum survival rates.

Secondly, with my pre-kneaded aquakneadit, i use a small 5cent piece ball size blob of the putty, (or similar amount of reefgel or superglue) and push that into the dry plug to be used.

Thirdly, i firmly push the frags into the putty, and mold the putty around the base of the frag.

Fourthly, i leave the frag plugs OUT OF WATER for say 2-3 minutes, to allow the putty to cure in air. I sometimes dribble some water over the fragplugs as they cure.
I then carefully put them in position in eggcrate magracks, as the putty (or reefgel or superglue) may still be a bit soft, as it (putty) takes 5-10 mins to fully harden.

One thing i have noticed with this technique.... DO NOT attach your frags and then put them in a bucket of tank water to cure, the small quantity of water must become slightly toxic, due to the curing putty or superglue, as i have noticed poor survival rates when doing this.
It is far preferrable to let attached frags cure in air or in display tank.

I also use these and find them great due to the fact they are very secure in the egg crate unlike the frag plugs.

What I have tried experimenting with is actually super glueing pool dust onto the plastic first before gluing the frag on to try and increase encrusting rates (Eric seemed to suggest encrusting was quicker on a marble substrate). Unfortunately I have no evidence if this helped with encrusting as I moved my tank :(

Yeah I reckon they would be popular.

When I told the guys at the Monumental Works they were quite
interested.

I might look in to getting a bulk order and a price if there is any interest.
The only downside is they are quite heavy for the size.

I reckon 5cm x 5cm would be about the right size but obviously this
could vary depending on individual requirements.

I have had some in my prop system for a couple of months and they are
covering over nicely with coraline and the acro's are encrusting on to them.

Thanks

David
