I actually covered all the slits with lava rock to prevent blocking. That has been working on my other tanks.
Why don't you just get a chiller for your HK tanks? I think that is mandatory with the hot Asian summers. I don't think any Bees or Tigers will do well with HK summer weather. I wouldn't risk expensive shrimps due to the lack of equipment.
If my tanks was in Asia....I would have a PRL or PBL tank for sure...
