Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl rather than seawater) and at a temperature of 15oC59 0F rather than 25oC77 0F.

  This will make 1 year that I bought these gloves and they are still in service. For maintenance, water + soap. Very nice quality product. Attention if you're an XL, buy a L, it size very very big! Good jock-strap, effective maintenance, the correct cup, unbeatable price, what more to ask? IN addition, tthe size ordered was size received, so no worries. I would have preferred a belt that is less wide, but the fabric is flawless, to see with successive washings.. and the delivery was very fast, faster than expected.. 6 days instead of the 15 planned. the slip is very well it is a pity that there is not the shell with, so for now this serves me nothing. very good pair of gloves, well worn.... adapt the sport for what I order. I recommend themKeeper glove soccer for children. Because it tears easily. I'm a little disappointed. But its worth the priceDelivery super fast (under 2 days after the order), packing nickel, good quality fabrics.

But in any case, a XL Large!!!!!! Unusable disappointing... You know now!!!!!! I am Unhappy!!!!! Set of football bought for a christmas gift! The set is of good quality and the fast shipping. Happy with the product. What to say about these gloves, they are the satisfaction of my grandson; Resistant, what more can we say; correct Packaging and fast delivery. I do not regret my purchase. My son is very happy with this purchase! The gloves look solid but as they are white they are more messy! As usual the delivery was fast and neat. Thank you AMAZON ;) Nice quality. Held thick and well finished. It stands up to the loons on land in grass and synthetic. Held top-of-range compared to other brands. Good gloves football use from time to time to the house in moderate use but not in a club! There is already a hole in one of the gloves it is the foam that goes underneath.

  Otherwise courteous service from the seller and fast delivery.. I had chosen a size M. I find myself with a section labelled M, but in reality too large for me. I order another in S. apart from this appreciation of the sizes quite extensive, this jockstrap is of good quality and comfortable. my 9 year old son has adorésle problem it is the white, but these are gloves for football, so it is made to be color grass/terresemble resistant, to see on the longer termBeautiful bat cricket, we use to play rounders with our children. Suitable for adults and children from 7-8 years of age, otherwise it may be better to choose a size down due to the weight of the object. Only downside : gets dirty quite quickly. Good quality/price ratio, the gloves are of quality, the seller is serious and fast. The expedition is neat. Attention : the gloves tend to smell bad, it is necessary to wash them often. a little wide but not the elastic band. am not sure I am going to put bcp.... The pull is not in line with the announcement. Pay attention there is an error in the ad, this is not a "1%" acrylic 100% acrylic!!! Super my son is super happy, but a pity it spoils too fast... It was still a nice gift. We are happy with the cricket set. It's what we hoped. Perfect for playing with children in the garden. The Product matches the description seller. I recommend it as a low-cost and of good quality. Very good productShell practice for combat activities. Good protection. I recommend to take the slip or another to be able to put in place and ensure a good protection..
