Look, idk if I’m the only one who loathes putting my entire arm up to the armpit in my tank to clean it, place corals, etc., but I can’t stand it. Not to mention, might be putting oils in it, soap, even sunscreen. So I thought about how my veterinarian checks my horses for pregnancy, and ordered these arm-length plastic gloves to use in my tank. They work perfectly and are $12. Winning!
