So what has happened since the 1 year mark? Honestly, nothing good.
Unchanged: The hair algae is still a major problem. I slowly lost all of the corals I had added with the exception of the torch and hammer but those aren't in good shape either. :headwally:
Changed: I added a RDSB in a bucket to the system back in April. So far I'm not sure that it has helped but I plan to leave it in the system as it isn't hurting anything either. I added a bunch of turbo snails, Nassarius snails, and hermit crabs to the display and have since noticed bare patches of LR where the snails have done their thing.
Major Change: Last night I changed out the MD7 return pump for a RLSS DC6000 and added a Tunze 6065 to the two MP40s and MP10 that were already in the system. The Tunze went into the back corner and is pushing water the length of the tank. Its amazing how much junk can get stirred up when you change the flow patterns in a tank.
Adding the DC6000 caused me a bunch of heartburn for a very unexpected reason. Installing it was a snap as the outlet for the US version is 1" NPT and my return manifold is all 1". Considering the difference in flow I was amazed to find that the MD7 and DC6000 are almost exactly the same size. All I had to do was get a 1" threaded union, install the o-ring half to the new pump, and replace one with the other at the union. :bounce3: That was the easy part. The problem came when I turned it on I couldn't seem to get my Bean Animal overflow siphon to start. To make matters worse, the siphon tube in the overflow box was stuck in place. :angryfire: It took a long wire tie loop and some "persuasion" to finally knock the fittings out of the bulkhead in the overflow box. Turning it over I found the culprit, a Turbo wedged into the elbow. :debi: With the "obstruction" removed and returned to the tank, I was finally able to balance the drains to the new return pump.
With the changes made last night, I'm now going to wait and let things settle out. With the increased flow I hope to see the two surviving corals opening up more and maybe the anemone will be a little happier. If the algae disappears I may rework the lights back to T5s and consider doing corals again. For the time being, not loosing ground would be an accomplishment.
