Est-ce normal si la vapeur vient de mes cheveux quand je utiliser un spray de protection thermique avant que je le redresser?
J'ai été en utilisant un spray de protection thermique récents à cause de mon endommagé cheveux. Mais, lorsque le produit i elle que de renforcer la vapeur / fumées sort est-ce normal ou dois-je obtenir une pulvérisation différentes?
Il est parfaitement normal, cela signifie juste que le redresseur est en contact avec le spray. La protection contre la chaleur fait son travail et créant une barrière entre vos cheveux et le lisseur. Pas de soucis. Je ne vous inquiétez pas si vous n'avez pas utilisé un protecteur et vous remarqué de la fumée crachent de vos cheveux-qui ne serait pas bon

What can I substitute for pool chemicals, chlorine, alkalinity, ph etc?
I have had my above ground 15,000 gallon pool up for 2 weeks now. I have already spent 200 bucks on chemicals. Is there anything that I can substitute these chemicals with that is cheaper. Chlorine, alkalinity, ph, flock and I know i am forgetting some stuff oh yeah algaside 60 that kills algae.
Ozone is the best choice. Ozone is a “green” alternative to Chlorine or other toxic chemicals that people ignorantly expose themselves to every day. Chlorine has been proven to cause cancer in many studies, and when it reacts with food, you get toxic byproducts that create cancer (see sources below) Ozone on the other hand can even rid your pool water of pharma drugs which are now in almost all municipal water supplies! Ozone breaks up the bonds to pharma drugs, making them harmless.
You’ll need to spend around $400 on an ozone system that can handle a 15K gallon pool. You will be able to eliminate Chlorine and only shock the water every now and then with a non-chlorine shock agent like potassium monopersulphate.

Can I use Pavestone Pool Filter Sand for my aquarium?
I went to the Home Depot, and got a 50 pound (well I think its 50 pounds) of Pool Filter Sand for my fresh water aquarium (55 gallon), about 5.88 bucks. Its Pavestone brand. And the bag pretty much says nothing of useful info.
It just says “Pavestone Pool Filter Sand” and something about being great for pool Filters, and that its .5 Cu. Ft. What does that mean??
It does not state if it contains chemicals or if its silica or that other one. Has any one tried this brand of Pool Filter Sand for their aquarium? ANd Is it 50 punds??
I just started washing this stuff, and the grains look crystal-ish, with some specs of brown and black, but when I started the wash, the water turned brownish and the sand looks brownish, I thought Pool Filter sand was supposed to look white? Since I been looking for pics about it online, most of it looks white, mine is brownish? Is this sand OK?
As far as I know, Pavestone Pool filter sand is mostly silica.
Being great for pool filters means, well, that you can use it in a swimming pool filter.
.5 cu. ft. means the bag contains one-half cubic foot of sand. A cubic foot is a unit of volume that is one foot wide, one foot long, and one foot high. A cubic foot of sand would fill a box that size. .5 cubic foot of sand would fill a container with inside measurements one foot wide, one foot long, and one-half foot (six inches) high. One cubic foot is about 28.3 liters, or 29.9 quarts, so .5 cubic foot is about 14.15 liters, or 14.95 quarts.
I would expect .5 cu. ft. of sand to weigh something more than 50 pounds, but it depends on the kind of sand, and in any case, .5 cu. ft. is a measurement of volume, not weight, so the weight might vary a little from one sack to the next.
Pool Filter Sand is generally safe to use in an aquarium, but it is not the best substrate in my opinion, mostly because it is too fine for most aquarium purposes. It will tend to compact in the aquarium, trapping organic wastes that then decompose into toxic gases. It also will go up the siphon hose if you try to vacuum the bottom of the tank.
Edit: Lots of sand looks more or less white when it is dry, but brown or tan when it is wet. This is true, for example, of the beaches near me in Texas (which might even be where Pavestone gets its sand). I don’t think the color is anything to be concerned about, unless your design for your tank requires white sand, in which case you need a different kind of sand. What is important, in the washing phase, is to get out all the dirt and fine dust that the sand may contain.
