Quad DE 100 filters do not need to be cleaned any more frequently than once every 6 months. You can actually go a full year if need to assuming not much falls into your pool. The problem is that these are big filters...they are a pain to clean. Yes, it's all nice and easy to take a part..but...

Thanks for all the feedback, especially from Jim and Philo. I should clarify that I do suspect there is a modest leak somewhere as I'm having to put in 1lb of CYA and 25 lbs of salt roughly every month for the last 6 months. In fact, the CYA has always been somewhat unstable...the longest I've...

Jim, The intellichem runs the IC60 at 100%. It just adjusts when the IC60 turns on/off based on a fixed cycle of 120 minutes on for every 20 minutes off, limited only by the pump on time -- currently 13hrs..but if I lower the pump speed, I might be able to get to 16hrs/day. FC oscilates...

One expects a certain amount of trials and maintenance when owning a pool, and to a certain extent....I've done alright with my 7.5 year old backyard in ground masterpiece.... But, the mysteries of keep chlorine at reasonable levels during summer months here in San Diego are a constant chore...

I sent an inquiry to our pool company regarding whether they installed a brodie valve and if the hydrostatic valve was automatic or if there was a way to test it before completely draining the pool.

We have a basin for water removed from the pool cover, and various drains drilled in the deck floor to keep the pool from overflowing when there is rain..but as far as I know nothing for groundwater or any associated pump. Thanks for the idea..I hadn't heard about that before. I'm...

Hello, Our pool was built ~3yrs ago and the builders comprehensive warranty for any issues is about to run out. Over the last six months we noticed a rust stain developing on a deep end wall nearest to a backyard hill. We've worried for awhile that there might be a water seepage issue with...

SWG installed in late January of 2012 for 24K gallon pool. In use with intellichem system. - Pump on 12hrs/day, Intellichem active 11hrs/day, SWG running at 100% for about 30 minutes out of every hour on average (much less in winter, much more in summer) - Have had SWG issues in past but always...

Dolphin marketing is horribly confusing, partly because they produce separate models for different geographic regions and/or resellers and then update them annually. It comes across as schizophrenic. Both dolphin and aquabot make high quality robots. I'd suggest identifying the closest robot...

Just stay away from the barracuda suction powered cleaners....there have been several reports of those not being nice to pebble tech. In your case, I'd recommend a dolphin robotic....aquabot would also likely work....the high quality robotic cleaners usually have a choice of brushes....just...

Dolphin deluxe 5 is a great robot -- you'll be happy with it. If taken good care of, should also last a long time with minimal repairs. Just be careful when taking it out of the pool, you have to manually grab the handle when it gets close to the surface (do not tug on the power cord) and it...

I'm familiar with intellichem and not intelliph but I thought both work roughly the same as they were both released about the same time and share common parts: Doesn't the intelliph have its own lcd interface? what does it show/say? As for interaction between intelliph and intellichlor, isn't...

Yep, unless you have very cheap electricity and regular high air temps and humidity, heat pumps don't really heat up water that fast or efficiently. But, they sure are easy, relatively inexpensive and safe way to provide a backup to a main heating system - and if your main heating system is...

Don't forget temp impacts how fast it dissolves...and at the start of the season, a large sock can surely take 5 days to dissolve...if you are starting from 0 cya, and multiple socks are needed, then you could be looking at a several weeks to get cya up to where you want. We did reverse osmosis...

Water temp reached 78 degrees today using just solar heating - I expect it to be 80 tomorrow since it has been gaining 1-2 degrees/day. Looks like our swimming season is effectively March-Nov.

Solar is the most effective heating, but it is very temperamental. Clouds/rainy periods can shut it down for weeks. Heat pump is a great backup for Solar and in general, should probably be considered part of most solar installs. I wouldn't use it for primary heating unless you have very cheap...

Re: Has anyone hooked a flow meter to a pool with an Intelli I actually have a digital flow meter installed on a dedicated long pipe after an intelliflow VS with a relatively new pool and large DE filter. All sorts of things impact efficiency of the pump, including how much inflow is coming...

Just as an update -- We've had the intellichem for over a year now and just had the first annual maintenance done. * PH meter has been super accurate, always staying within 0.1 of taylor and responding quickly in realtime to upticks from the SWG or changes from any other chems added to the...

A good solar company can do marvels by analyzing your current setup and tuning things. Unfortunately, from what I can tell, it appears that they are rather rare. We ended up in a dispute with the first company that did work and had a second company come in to fix what they did...and it was a...

Re: How much to worry about CSI after pool wtr reverse osmos K, I had been keeping CSI in a tight zone between 0 and -0.2 ever since the pool was first started up...glad to hear that -0.5 should be safe enough until the water temp increases. That is a lot of stress off my shoulders. In any...

Calcium in our pool reached our high threshold point earlier this month and we had reverse osmosis service performed to bring it down. And, yes, it brought nearly everything else down as well. PH dropped to 6.8, TA dropped from 120->50, Borates went to almost zero, salt to 800, CYA to under...

Just as a datapoint, we put in a quad de 100 for our 24K gallon pool. The pool is covered which removes most debris from entering it. The DE filter handles the rest and we find the water sparkingly clean and most visitors comment on how clean the pool is compared to others. The filter only...

We had a pentair tech out when we installed our intellichem to ensure all was installed properly, and we put the acid/flow return before the SWG and incoming after the filter but before the solar valve. It's worked fine. If you want, I can post a picture.

Hmm....the local san diego grocery store carries 20 mule team borax, I didn't even bother looking for other sources....

Thanks for the info! I assume TA reduction would also be a nice bonus. I'll give it a try for big storms going forward and try to collect my own data.

I guess the question is how much new water do I get with rain.....yes, that will depend on the weather and location.....we don't get a huge amount of annual rainfall here in San Diego, but we get at least a few days non stop here and there during the rainy months....even if I pumped out water...

Been awhile since I've last had to post, however the next pool season is almost here and our pool's CH has just crossed 500....and I checked the weather for this weekend, looks like almost two days straight of rain....and it's already started. Can I just open the auto cover and let new rain...

This week I had to switch the pool loadcenter/power to service briefly in order to restart the pump after finding that the kids had clogged the skimmer and the pump was sucking in air. After fixing things, restarting, and putting the system back into 'auto' mode -- everything seemed to startup...

I've been running an intellichem for ~10 months now. We had a one-time issue during the first 90 days where the pump and cabling was replaced. Since then, it has been running problem free. Never had pool water back flow into the tank, but then we were very careful with the setup. I don't see...

Minimum Target FC has been 7 with CYA 45-55, SWG usually kept in a 7-10 range. CYA deliberately kept around 50 as that is the highest level compatible with an ORP controller. No, I haven't tested ammonia as the test isn't included in the default tfp test kit, it doesn't appear to be a...
