How do I care for and clean my test tubes?

Once the test has completed, it is important to rinse the test tube with water right away so that the contents don’t stay in the test tube. This will make sure that the reagents don’t cause anything to stick to the sides of the test tube, which could cause staining over time. 

Simply run the water, open the test tube gently (do not twist the cap), and allow the water to dilute and rinse the contents out of the test tube. Avoid getting the contents of the test tube on your skin.

If you find that you have forgotten reagent within your test tube for a long period and the color is sticking to the tube, you are able to use a small bottle brush (and some API Safe & Easy cleaning spray) to gently wash the inside of the tube. Avoid the use of soap, as soap residue could be introduced back into the aquarium when filling the test tube at next use, which is something that could be harmful to your fish.

Replacement test tubes are also available for purchase from online retailers, should you need additional test tubes.

How hard do I shake the test tube when performing the tests?

While it is important to shake the indicated reagent bottles very vigorously, you should be gentler when shaking the test tubes during testing. Before shaking, make sure that the cap is closed tight.  Place a finger or thumb on top of the cap, to make sure it cannot come undone during use.  The goal of this shaking step is to mix the contents of the tube together and this can be accomplished by simply inverting the test tube, back and forth every 1-2 seconds, for the indicated amount of time.

Works
Color: Mayday
A little does go a long way. It’s on the pricy side but it was worth it. It’s not something to be using all the time. But definitely a back up for whenever you do get sunburn

Really effective!
Color: Mayday
I was totally blown away by how effective this was on my recent burn, I wish I had taken pictures. So much so that I did a deep dive into the ingredients and formula (I'm a nerd). My takeaway is that this is a bargain for the quality of ingredients and the care of the formula. The product absorbs quickly, is non-greasy, and relatively moisturizing and most of all, really effective. I personally appreciate the lack of any real scent or fragrance. I'm a big fan!

Not the results I expected
Color: Mayday
I sooo wanted to love this product; however, the results were not as I expected. Especially at this price point. I have sensitive skin & actually broke out, so maybe I am allergic to one of the ingredients or applied the product too thickly. I’ve experienced better results with Coola’s Radical Recovery Organic After Sun Lotion which is only $32 for 5oz, so it’s definitely more cost effective & delivered better results in my opinion.

Could double as a sun safe Uruk-hai cosplay
Size: 5 Ounce (Pack of 1), Style: SPF 50+
This sunscreen is amazing. Was in the sun off and on all day. One thing though. Make sure you apply with a mirror in front of you or you may end up walking out the door looking like a Uruk-hai from LOTR. I was in an allfire, trying to get to the fun part of my day, and rushed putting it on. Just as I was about to leave the hotel room I caught myself in the mirror. Complete white hand print on my face where I hadn't rubbed it in well enough. So yeah, works amazing, no sunburn, and needs rubbed in well. LOL

The best sunscreen on the market
Size: 5 Ounce (Pack of 1), Style: SPF 50+
The best sunscreen I've ever used. I burn super easy, just 30 min outside without protection and I'll be a lobster the next day. I can apply this once in the morning and be protected all day. Pros: - Doesn't wear off quickly - Haven't had a single sunburn since I started using it - Doesn't have a strong chemical smell - A little goes a long way - Resists sweat well Cons: - Has a white cast so you really have to rub it in - It doesn't sit light, you can definitely feel it on your skin I would recommend this to anyone and everyone looking for sunscreen.
