I just got my subtank mini today. I washed it right after I opened it rubbed each piece in hot water and dishsoap then soaked in a bowl with hot water and dish soap then rinsed and soaked in hot water couple hours. So hopefully its clean lol. Atm its drying been 3-4 hours. Seams dry already but I wanna make sure theres no water left in airflow base. So this is my first sub tank. I only use rda drippers. I heard you need to prime them it says on packaging to put a few drops in coil head and then let it sit with tank full for few min.. ill probably give it half hour atleast. Also heard to start at low power. Its .5 coils i have. So should i start at like 15 20 watts.. and slowly go up. But at what pace.. should I up it say 5 watts every few min or wait much longer. Just wondering how you guys that have sub ohm tanks do it to prolong coil life.
