I too have a copy of the HP remedy but haven't plucked up the courage to use it yet as in previous threads discussions have been quite heated about it. Some have had great results from it and others are quite against it. I am still really open to trying it so will be really keen to see what results you get. At the moment I am giving my girls mashed pumpkin in their feed once a week and that seems to be helping them to pass the sand. I tried the psyllium husk treatment for a few months but both my mare and filly had to be drenched still (mare about 4 weeks ago and filly last Tues). I have only been using the pumpkin for about a week but can definitely see the results from it.
It is so hard deciding as to what method of sand prevention treatment to use as everyone has a different opinion on each method and all horses are individuals. I am at the moment just trying to find out what works best for our two and finding out as much info on all methods as possible. I will be watching this thread with interest.

I've purchased the recipe and also used it with fantastic results. Having said that, my horses came down with colic 3 weeks ago. I should have given him the recipe just as the new rains came to contend with the new grass. Have now marked on the calender to do him just before summer, and then just before winter again so twice yearly.
You can only give it a try? If it works it's MUCH cheaper than a vet!
I went to John O'Leary's website and really his very own best advice to avoid sand colic was just good horse management - mainly feeding LOADS of hay. At least 6 biscuits a day! So I don't see why you need to buy a special product too - even from him!
Also there's a study (sorry can't find link right now) showing hay beats psyllium in shifting sand out of guts. Haven't seen research checking out pumpkin mash tho. It's hard to tell what has worked or if you've been lucky, unless you have a big trial to compare treatments with. There's so much sand colic in Perth I wonder somebody hasn't run a trial on prevention (any vet/equine studies honour students- looking for a topic?)
I see heaps of people underfeeding hay (can't help being nosy) and often these are the first to get hit this time of year. The horses are eating little sand castles with each mouthful of new grass.
Caroline - rolls of hay and he's still eating sand? What a naughty boy! I also have a QH X gelding and he grubs in the sand like a little piggy - always after the oats So far he's lucky and never had colic (though am touching wood right now!!)
Like people - they have different table manners, some dainty and others sloppy and throw back roots and all. But at the moment it's extra hard for any to pick grass from roots. I've heard windsuckers do it tuff cause if front teeth are worn it's all hoovered down (is this true?)
