Today, I changed out the 5 year old membrane in my RO/DI system. And while I was at it, I decided to document the process, so that anyone that has one of my RO/DI systems will now know how to change the membrane.
It is definitely time for an update.

Regarding Reefcast: The podcast is a hobby, and we do it as time permits. Evan's job devours Monday through Friday, and his weekends are pretty busy as well. Weekends are really the only time we can record, and DFWMAS (my club) has taken up many of them this year (planning and execution of our Next Wave conference, and now the complete rewrite of the club's bylaws). I just talked to him yesterday about how we recorded back on Feb 10th and on March 18th the show was still undone.
A new page has been added to the site:
How to change the filters in an RO/DI unit.
For a long time, I hated the returns on my tank. InterAmerican drills the return hole in the overflow box, below the teeth. On a larger tank like mine, a couple of inches equals a lot of water in the sump. So I solved it by adding twice as much locline, and had it shaped in an arch. At the apex of the arch, I drilled three holes in the underside to break the siphon and stop draining so much water. This worked great, until about 6 months ago when I soaked the locline in muriatic acid, which cracked the joints and allowed more water to seep out quietly.
I've been running the new VorTech pump in my tank for the past three weeks. I'd like to thank VorTech for letting beta-testers speak publicly about our impressions finally.
When I opened my box, I swear I heard angels in the heavens singing. 
A few days ago, I heard a loud "pop!" but couldn't find the source. Since then, some random corals in my tank have not been doing well, and I couldn't figure out why since others were perfectly fine. I found the source.
MaxiJet Modification
If you'll take 10 minutes and a couple of common tools, you can alter a Maxijet to increase the flow in the tank quite a bit. I was told how to do this, and finally decided to try it out. It worked!
Using a hacksaw, I cut off the jet off the impellar cover.
After using Phosbuster Pro probably about 30 days ago, I'm still seeing cyano bacteria in my reef tank. I decided to go ahead and dose the tank with ChemiClean to erradicate this stuff so the corals don't risk getting smothered. I waited patiently but it isn't going away quickly enough.
During treatment, the skimmer is turned off for 48 hours. Time to make another 55g for a water change. The label states to change 20
