    How safe is the putty you get from the LFS to stick coral?
    Was swearing and cursing a few minutes ago.
    Had a frag stuck to a piece of rock few minutes before.
    Thought I'd be clever and detach it from the rock and stick it to my LR - except the "£$%ing putty broke apart and started dissolving.
    So my water turned pink and theres little bits of putty all over the show!
    Plus the poor SPS received far too much bad handling than he should have.
    Is the putty safe in my water (will it be removed by the filter) and will my SPS be OK or is it cause for a bit of concern?

    It's reef safe but use Pratleys putty which is a thousand times cheaper than the stuff from theLFS. Use the quickset and you can add a drop of pink food colouring so it's not white in the tank. Mix it up and leave it for five minutes so it starts setting then place your corals. Remember to turn all your powerheads off so they don't move the coral frags

    Thanks Tony I'll get some Pratley's.
    So it's safe to assume the dissolved putty won't affect my water quality?

    The reef putty seems to do that, it always breaks up. I've found the trick is to put the mixed puty in the microwave for about 10 seconds after you have mixed it. This makes it softer and stops it from breaking up. Also once you put it in the water it is best to try and touch it as little as possible, the more you fiddle with it, the more that white powder stuff comes out. Also putting it the microwave makes it harden much quicker...

    I just use pratley putty now, works much better and have found my sps corals encrust over it more quickly than the proper reef putty...

    It skims out all the powdery stuff released by the putty in the curing process...

    Guys, the best would be to use Pratley's "Normal set" white putty. It sets much stronger under water, and does not "dissolve" into "mud" when broken up at a later stage. It does take about 6-8 hours to set properly, though, and during this time the frag should be supported, and the water flow should also be reduced drastically to ensure that the putty sets without being disturbed.

    Platley's "Quick set" putty works quite well, and I have used it on many occasions, but id does not set very strongly under water. It also appears to lose strength over time (years...) and tends to "powder" more when broken up. It does set within a few minutes, though, and this makes it very tempting to use, especially in difficult places.

    Personally, I would not add any colouring to the putty, as it will weaken it. It is also unnecessary, as the putty plug will be overgrown by the coral in question, or by coralline algae, within a few months.

    also think we must be careful with the amount of putty used.... obviously if just for a frag the amount is small, but I feel that if someone uses the entire pack of putty once off (perhaps to secure a rock in place) this can be dangerous to life in tank ... or am I wrong ?

    i would agree with you on this in general .... but it would depend very much on the size and age of the system and the filtration capabilities of the tank !

    There have been times when I glued a whole lot of frags down and used about half the box without any ill effects except for the skimmer going mad

    They say it is not toxic at all. I use Pratley and no ill effect whatsoever. The marine putty the LFS sell is way more expensive as well. :razz:
