Liz Pool

Thanks for your response. The basic question I am asking is: What method can be used to measure living things in the water that are harmful to bathers?

What tests or instrumentation are used to measure the level of sanitation or safety in a spa which uses no chlorine or bromine? What method can be used to measure living things in the water that are harmful to bathers?

I have a 1000 gal therapy pool that I use for my daughter with cerebral palsy. She is allergic to chlorine and we had to stop going in for the last few months. I am trying an alternative sanitation system sold by CUZU Water Systems. It is a 4" sponge like disk that is claimed to provide sanitation without chlorine. Has anyone tried this product? I am currently testing a fresh fill.

We posted for the first time a few weeks ago and now are ready to fill. We have a vinyl therapy pool (6' x 6' x 51' interior) for our daughter who has cerebral palsy. Reading the information on the internet and this forum, we have opted to follow the Dichlor/Bleach Method. Our therapy tub/pool holds 1000 gals of water and we will heat it to body temperature, ie 98-99 deg F. There are no jets, just suction and return lines. We are putting it in an insulated garage that never fails below freezing on concrete. We have a Waterway 1/8 HP circulation pump (30GPM) with a 25 sq ft cartridge filter and a raypak electric heater 11KW. We will use it daily, 2-3 people total to support her in the pool, she cannot stand but benefits from the hydrostatic pressure, buoyancy and warmth. We would like to use minimum chemicals since we will be using it daily. We purchased the Taylor K-2006 as suggested and measured the tap water. We have city water which is rated very good nationally. The results of the tests are as follows: PH 7.8 TA 110 FC 0.8 CC 0.3 CH 75 CYA 0/trace We have purchased the dichlor, bleach, muriatic acid, baking soda and are not sure on the borax. The CH is a little low but we have read the posts on the forum and a little low is ok. So do we fill, then turn on the pump, filter and heater AND add the 10 ppm shock of dichlor all at the same time? When do we adjust the PH with the muriatic acid? We don't want to damage any of the equipment.

We have a question on the proper placement of suction and return fittings both 1 1/2" dia. The body of water is a 7' x 7' x 50" vinyl therapy pool. Do you put the suction near the top surface of the water? What about the return? The pool will be heated to body temperature.

Thanks to all who posted replys! It is a little overwhelming to absorb all that must be learned to manage the therapy pool environment. Our goal was to use as few chemicals as possible since Liz would be in the pool everyday. We have read the previous forum posts regarding mineral bacteria control but it requires the use of a sanitizer anyway. Same thing as with an ozonator. So we will try the chlorine method suggested. We have ordered the K2006 test kit and will get some Dichlor from the local supply store (Chicago area). We tested the tap water with test strips and can see that they are not very accurate. We picked out a pump/filter package that will filter 30GPM. Now we are looking at electric heaters and two seem like good choices. Raypak 11022 11KW and Hayward CSPAXI11 11KW. Both will require 240VAC, 60 AMP circuit. Raypak is about $75 more. Any suggestions welcome. When the pool arrives, we will need to cut round openings for the suction and drain fittings. We are curious what is the best height for the return/drain line? There are NO jets, just the two lines to and from the pump/filter/heater. Would more than one return line, e.g. one close to the bottom and one about half way up be better? The cover we ordered is a bubble pack type we plan to attach to a sheet of ridgid insulation and lay the bubble pack side against the water. The thought here is to keep the cover in place to reduce heat loss. More insulation on top of the pool and sides may be necessary as the weather cools even though the garage(faces South) is insulated, R40 ceiling, R22 walls, and R8 doors. We are also working on an entry/exit system that will be safe for carrying Liz in and out of the pool. A lot to think about! P.S. To footie. After 30 years with a CP child nothing offends us anymore. Liz has a number of serious motor problems that prevent her from speaking, walking, standing or sitting without support but so far she has excellent bowl/bladder control. Her muscle spasms are reduced with the warm water pool.

We have a 1500 gal therapy pool and are shopping for a heater. If you have experience with Hayward CSPAXI11 or Raypak ELS 11022, both are 11KW heaters, we would like to hear your about your experience.

We have recently ordered a therapy pool (7' x 7' x 54' vinyl) for our daughter who has cerebral palsy. Reading the information on the internet and this forum, we are confused which chemistry we fit into. Is it a pool or a hot tub? The spas seem to have water volume limits around 600 gals and the pools are 10,000+gals. Our therapy tub/pool holds 1500 gals of water and we will heat it to body temperature, ie 97-98 deg F. There are no jets, just suction and return lines. We are putting it in an insulated garage that never fails below freezing on concrete. We have ordered a Waterway 1/8 HP circulation pump (30GPM) with a 25 sq ft cartridge filter and a raypak electric heater 5.5KW. We will use it daily, 2-3 people to support her in the pool, she cannot stand but benefits from the hydrostatic pressure, buoyancy and warmth. We would like to use minimum chemicals since we will be using it daily. All suggestions welcome.
