I got a Diver in a trade and there were no instructions but I've followed the greek youtube vid on how to fill. I first had the Diver in a Phiniac tank and got dry hits. I now have it in a top fill prive clone. I filled from the top like the greek youtube guy did and it floods. I tried filling through the top fill hole and it floods. I filled it half way like instructed. I'm using 100% VG diluted with 5% distilled water. What could I be doing wrong?
