Dual 250 gallon Marineland Monterey Deep Dimension build

Blue star polyps will spread like wild fire. They send out something that spreads everywhere. They will literally be on every square inch of your rock
very true. I have a friend that lost a lot of corals due to them. The only way I know to get rid of the is fluke tabs once they start spreading. My LFS just broke down their big display tank cause it got over run by em.

Your tanks are beautiful btw
 
That won't help. I tried that I knew that they spread like crazy, so I left them in frag tank hoping for the best. Hope didn't help. Blue star polyps send something into water column. They ended up stairs in my display.
 
I re-mounted my eight (8) Photon 24's using 24" Incra T-Tracks. The units are mounted inside the canopy of both my Marineland DD 250's. The two units in the back hang about 2" lower than the from two units. I can slide them in and out for service/reprogramming. I installed a stop at the rear of each track to prevent someone from pushing them through.

Biggest challenge was disassembling each unit to replace the mounting bolts with stainless steel hardware. Took about 20 minutes each, this became a full afternoon project yesterday.

The tanks are cloudy because I just finished a major cleaning and stirred up the sand bed.

My right hand side tank almost crashed from a horrible outbreak of some type of snot diatom. Covered everything and smothered most of my polyps. I tried everything, and it only has just cleared up when I installed a Reef Octopus BiChurn 170INT reactor. Things are now returning to normal, although I will need to rebuild my soft coral stocks.

Funny thing, all during the outbreak, my nitrates, phosphates and silicates were almost undetectable. Even stranger given the high bioload on this tank. I suspect they were tied up in the algae.
 
My new Passer Angel. I haven't had one of these in over 20 years. He's been in QT for ten days now, only 20 more to go before he joins the other large fish in the right side tank. He started eating like a pig on day one, and feeds heavily on NLS pellets.

Sump updates

Sump updates

I did a lot of work this morning cleaning up and organizing my sumps. I wanted to clean the impellers of all the return pumps, and cleaned up some of the salt spray that has built up over the last 18 months or so. I also double checked the bulkhead fittings, and straightened out the cords.

You can see my new Reef Octopus Biochurns in the photos as well. I installed a 170INT on the right side tank (bigger fish, higher bioload) and a smaller 120 INT on the left side tank.

This is the sump on my left side tank, I call it the Tang Tank:

Neptune Apex controller

Neptune Apex controller

Adding an Apex controller to both tanks. Spent most of the day working on configuring. Pictures soon, but somewhat frustrating.
 
Beautiful tanks you have there.
On the Tang tank, how many yellowtail damsels do you have in there? How long have you have them? Do they kill each other at all?

thanks

I have eleven (11) yellowtail damsels, and have had them since I started the tank approximately 20 months ago. I haven't noticed that they are killing each other off, but each one seems to have selected its own little portion of the reef to call home.

I did start with about a half dozen blue devil damsels, but they all died one by one. I had about ten reef chromis, and they battled down to the two that are left.

Thank you

Neptune Apex

Two weeks ago I started installing an Apex controller for both tanks. I had the left side fully automated last weekend, and tackled the right side tank this weekend. Everything is now fully installed as follows:

WXM - Controller for Vortechs in both tanks
PM2 - Conductivity meters in both tanks
PM1 - pH and ORP monitors for both tanks
ALD - I have two (2) Automatic Leak Detectors, with five (5) leak sensors, two (2) inside each stand and one between both tanks
BOB - One breakout box for each tanks, which controls my ATO (2nd float with is an emergency shutoff), and a fill sensor float switch on my skimmer waste container to shut off the skimmer when the waste container fills.
Auto feeder - Right now I only have one auto feeder on the left tank. The right tank is fishless because of another Ich outbreak (more on that later). I will install a autofeeeder once the tank completes a fallow period.

Programming was something of a PITA. I eventually got the hang of it.

Enjoy the pictures. I installed it by mounting it on 8020.

This is the right side tank. The wiring is a little cluttered, as I ran out of 8020 connectors.

wish mine looked as nice and clean as yours

David - Thanks. My right tank got hit with Ich (again). In addition to wrapping up the Apex installation on Saturday, I had to net everyone out. I suspect it was my PBT, although everyone goes through an 8 week QT. Everyone is now in holding tanks or brute trash cans undergoing a cupramine treatment. the right side DT will remain fallow for 11 weeks. Any advice on ridding PBT's from Ich?
