Is there a chemical way to lower cyaneric acid (stabilizer) in a pool ? I remember seeing an add in a pool publication for a chemical to reduce cyaneric acid in pools. Does any know where it can be found and what is it?

If you are heading to Hawaii, make a quick stop in San Diego to pick me up and then we'll have 10 days to talk!
I go your VM late last night, and I will give you a call later today. You may be in the air and I may hit your VM, so give me a call back at your convenience if that occurs.
Talk to you soon; have a great time in Hawaii!
Hi Bruce
I am heading to Hawaii on Thursday to do cpo class. I will be there ten days.
I have been visiting with several of the pool service companies.
Trichlor is chemical of choice.and CYA build up is a real problem over there.
As a green alternitive to drain and fill . I thought your system would an ideal fit.
I am looking to promote your unit on a commision bacis..

Hi John-
I do not know of anyone who is packaging a unit in the production sense. We initially were going to partner with a company out of Phoenix, but that did not work out (nobody's fault on either side, just not quite ready for what we all wanted to do at that time), so we built our own. I have been in the water business for a very long time, and in the swimming pool industry for nearly 20 years, and I knew a very good RO man. It took quite a bit of convincing to get him to build the RO portion of our rig, and it operates better than any of us had expected. We've made a few tweaks since we first built it (it calls our phone when it is done, and we can remote start and stop it via texts, for example), and we continue to improve it.
We have several rigs out to bid currently, and would be happy to do the same for you. Call me direct (760.535.8411) if you like and we can talk!
Thank you Bruce
How much does a setup like that cost to put together?
Does some one alresdy have a package put to gether?
Just finished up a 16,000 gallon pool today that we did our RO process on. We started with TDS of 5,700 (of which 3,790 was salt), CH of 640 and CYA of 90 ppm. Ending numbers were 870 TDS, 608 salt, 130 CH and no CYA. The cost to the customer was $400.00, right in line with the cost to do a drain and refill in this area. The big difference is that they most likely would have received about 300-350 CH from our tap water, had they drained and refilled.
A benefit from this is also that this water will require lower chemical levels to maintain, something which does not seem to be taken into consideration when doing a drain and refill. I doubt that we will have to see these folks again for another 3 years or so, as their water will stay low in calcium for quite a while, as opposed to how quickly it rises when starting with high CH water.

Thank you Bruce for reminding us about Reverse Osmosis (RO). Yes, that is a very effective way of lowering the CYA level. Depending on the availability and cost of water, RO can be reasonably priced if it is available in your area. From my recollection of posts at TFP, however, I didn't think it was less expensive than partial drain/refill except in areas where one had to truck in water. Note that RO will reduce other chemicals as well so is also effective at reducing Calcium Hardness (CH).
Some melamine products were on the market many years ago. Most if not all are gone now. As Richard stated they created a huge mess in the pool. I worked for a chemical company in the eighties that tried to launch a melamine based CYA remover and we got pallets returned because of customer dis-satisfaction. The RO sounds interesting. Most proven method is drain and dilution on a maintenance basis to keep level consistent. 30 - 50 ppm.
RO, reverse osmosis filtering of the pool will remove it for much less than a drain and refill
There was a product called Clor-Mor Cyanuric Acid Reducer, but I don't know if it is still available. I believe it was melamine and it makes a cloudy mess of the pool, similar to what happens in the CYA test. You then need to filter out the precipitate, possibly using a clarifier to help, but there will be dissolved melamine-cyanurate leftover so if the CYA rises again there will likely be some additional cloudiness.
In short, there is no good way to reduce CYA except by partial drain/refill.
