Thank you for sharing this process! I'm building a sump and will be implementing your design elements on my new sump. I'll add one compartment between the drain and K1 baffles for seeding which I'll use later for mechanical filtration.
Thank you for your nice compliments! Most encouraging!
@glamit - have fun in Manila but make sure to hit the beaches of boracay and palawan!
@Boydo - trying my best to stay on top of things! And loving it!
Thanks, Chen! Yes, it is from Pang Long and roughly about 12"-13". He's eating very well and chumps pretty much anything I throw in the tank. Its just the rays and the aro in this tank.
