Is it ok to have spare saltwater mixing all the time?

[blue_eyes53813]

OK silly question. I once read somewhere that there is a possibility or that calcium or ect. will evaporate out of saltwater that is mixed or not used within 2-3 weeks. Reason I am asking is that I have two big drums that hold fifty gallons each. One is for R.O topoff water and one is for mixing saltwater. My boyfriend wanted to have the saltwater drum full at all times and mixing the pre saltwater for water changes..... OF COURSE we got in a huge arguement , Is it true that saltwater mixing in the drum will eventually lose or evaporate the good elements in the mix? I change 25 gallon every two weeks or of course 50 gallons monthly.... Can saltwater me mixed that far in advance?

Only h2o evaporates leaving behind the salt/minerals, etc. Keep a check on the salinity (using a refractometer) and add fresh water as needed.

BTW... arguments are fun... well, the making up is anyway

[Witfull]

make sure they dont leach phosphates. mix up some water and let sit for a few days and test. some plastics leach PO4. also keep the water moving to avoid stagnation.

Use good food-grade mixing barrels, and you should be fine. I kept 30-50 gallons mixed at all times, and the same in RO/DI water. Did so for MANY years, and never had ANY problems with either.

Descriptions
Polyethylene Terephthalate (PET, PETE). PET is clear, tough, and has good gas and moisture barrier properties. Commonly used in soft drink bottles and many injection molded consumer product containers. Other applications include strapping and both food and non-food containers. Cleaned, recycled PET flakes and pellets are in great demand for spinning fiber for carpet yarns, producing fiberfill and geo-textiles. Nickname: Polyester.

Properties
Clarity, strength, toughness, barrier to gas and moisture, resistance to heat

Packaging applications
Plastic soft drink, water, sports drink, beer, mouthwash, catsup and salad dressing bottles. Peanut butter, pickle, jelly and jam jars. Ovenable film and ovenable prepared food trays.

Descriptions
High Density Polyethylene (HDPE). HDPE is used to make bottles for milk, juice, water and laundry products. Unpigmented bottles are translucent, have good barrier properties and stiffness, and are well suited to packaging products with a short shelf life such as milk. Because HDPE has good chemical resistance, it is used for packaging many household and industrial chemicals such as detergents and bleach. Pigmented HDPE bottles have better stress crack resistance than unpigmented HDPE bottles.

Properties
Stiffness, strength, toughness, resistance to chemicals and moisture, permeability to gas, ease of processing, and ease of forming.

Packaging applications
Milk, water, juice, cosmetic, shampoo, dish and laundry detergent bottles; yogurt and margarine tubs; cereal box liners; grocery, trash and retail bags.

Descriptions
Vinyl (Polyvinyl Chloride or PVC): In addition to its stable physical properties, PVC has excellent chemical resistance, good weatherability, flow characteristics and stable electrical properties. The diverse slate of vinyl products can be broadly divided into rigid and flexible materials. Bottles and packaging sheet are major rigid markets, but it is also widely used in the construction market for such applications as pipes and fittings, siding, carpet backing and windows. Flexible vinyl is used in wire and cable insulation, film and sheet, floor coverings synthetic leather products, coatings, blood bags, medical tubing and many other applications.

Properties
Versatility, clarity, ease of blending, strength, toughness, resistance to grease, oil and chemicals.

Packaging applications
Clear food and non-food packaging, medical tubing, wire and cable insulation, film and sheet, construction products such as pipes, fittings, siding, floor tiles, carpet backing and window frames.

Descriptions
Low Density Polyethylene (LDPE).Used predominately in film applications due to its toughness, flexibility and relative transparency, making it popular for use in applications where heat sealing is necessary. LDPE is also used to manufacture some flexible lids and bottles and it is used in wire and cable applications.

Properties
Ease of processing, strength, toughness, flexibility, ease of sealing, barrier to moisture.

Packaging applications
Dry cleaning, bread and frozen food bags, squeezable bottles, e.g. honey, mustard.

Storring RO/DI Water

[Newt]

Great info! Thanks Doni

[mps9506]

We keep 40 gallons mixing all the time.

[blue_eyes53813]

Thanks all for the info.... Im not gonna tell him I was wrong lol , I use to keep my water in a rubbermaid trashcan before. I must have been thinking about that container not the big drums, Im still not gonna tell him

[Woodstock]

LOL~~ Come on... you can say it.... "I was wrong dear"

[blue_eyes53813]

lol I will try , I WAS NNT wrong dear,, sorry doesnt work. lol

[nigle]

Oi!

So Woodstock have I told you I love you lately, OK I haven't so......I love you!

I looked at my 31 gal Rubbermaid covered containers that I'm using and they are #5 PP,
so I guess I did a good thing Martha? I'm using them because the other slate gray
Rubbermaid's that I had that were more flexible sprung leaks, and I wasn't home at the
time [so typical] so I arrived with freshly mix salt water and top off water all over the
floor, [well one advantage was that I FINALLY did a good cleaning of the floor, HA!].

Your posts with the # was great, tanks!

Cheers!
