    Pentair Quad DE Filter - Do I need a Backwash valve?

    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...

    Woes and Tribulations of the IC60

    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...

    Woes and Tribulations of the IC60

    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...

    Woes and Tribulations of the IC60

    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...

    Conundrum regarding rust stain in 3yr old plaster pool

    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.

    Conundrum regarding rust stain in 3yr old plaster 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...

    Conundrum regarding rust stain in 3yr old plaster pool

    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...

    ic60 swg dying after just 2.5 years?

    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...

    Yet again, a robot question...

    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...

    Super large Pebble tec residential Robotic pool cleaner

    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...

    Looking at robotic cleaners and going nuts. help

    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...

    IntelliPH does not come on at all

    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...

    Heat pump users?

    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...

    adding stabilizer to pool

    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...

    Is it SUMMER Time yet?!!!!!!

    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.
