Wow it's pretty much 6 months later and I'm still at it with this tank. Update time!
Still no luck sourcing the RSM replacement fans locally in SA. May be forced to import them. Have tried a few different after market 50mm fans (hard size to come by) with varying results. Some are nice and quiet but at the expense of airflow and others are just the opposite. The RSM fans seem to be a good balance of noise and airflow. In the meantime though I've added some Sunon fans in there which are real loud but move a lot of air. Everything works perfect!
Been real busy fixing up the new house and that's delayed the tank a bit since I needed to finish up and make room for the mixing station. Finishing with painting at the moment so I won't have to move the tank once running.
Have made quite a bit of progress on the various mods and the tank has been cleaned and leak tested. RO source hopefully being installed this weekend and can start the cycle soon...fun times ahead!
My return pump plans have been realized and I've got my hands on a Jebao DC2000 that fits the chamber of death perfectly!
Some thoughts on my intended filtration setup:
-Have an InTank media rack now
-Planning on running purigen and matrix in there along with nitra guard biocubes to finish the rack off.
-Have the rack paired up with a tunze 9002 skimmer I picked up a while back.
-Also picked up a bubble magus mini 60 reactor a while ago that I knew would fit perfectly in the 130D. Plan on running some GFH in there eventually once the cubes have reached a good balance.
Ok enough talk. Here's what you guys came for...
Holes in the hood from the previous evaporative cooling setup needed to be mended
Used these pvc lids to fill the holes
A bit of silicone and spray paint later
