It doesn't seem to bother the clams....yet.... 
Thanks.
Thanks.
Randy, what type of venturi are you planning to use? I've been thinking about something similar. Feed the tubing with a maxijet venturi adapter or a true venturi?
I set up the ozone/air and water into the 100' of 3/4" HDPE tubing today. The flow is about where I want it (a little under 1 gallon per min; about 45 seconds of contact time), but the venturi is not sucking at that flow rate. If I remove the air line to it, water spurts out.

That long of a line is probably making too much backpressure. On this setup are you pumping air through the ozone or trying to use the draw from the venturi only? Could just be the gph vs. the venturi size. I'm sure there is a physics formula to use to determine the minimum gph for venturi action. I know a mj1200 will passivly pull air into my salt mix bucket but that would require a lot more tubing length to get the contact time.
I'm using an air pump, so it is going in just fine. From the look of the tubing it is about 1/4-1/3 air inside. The venturi is just a way to introduce the pressurized air.

Do you ever test the parameters? 21 fish in 350 gallons of water, 4 refugia, lit by 65 watt flood lamps and 1 skimmer. Feed your fish 2 times a day, 5 cubes at night and and a light snack in the morning.
Im wondering, how do you do it! :lol:
How deep is the sand bed, and how much macro algae is there? Just 4 little clumps of chaeto, or more like 4 big clumps? Im trying to visualize size and impact of filtration.
What would you say is keeping this tank in prime condition?

I just got some more fish. yellow clown goby. green clown goby, two honey damsels, and three more blue damsels (only 1 survived in QT from the first batch). The honey damsels went into the 90 where there is little to aggravate.
I don't think the number of fish is high for that large of a total volume.

where is the huge sps you had from your old tank? That was sweet!
I only transferred a small piece, but it is growing nicely. It is the piece that has a bunch of fingers stretching up from above the yellow leather:

Nice anemone.
What happens to the leathers?

You said you could not keep yellow leathers. What happens to them?

Oh they get that disease where they rot. The longest I have kept one is about a month. They sory of lose their strength and can't stand up, and shrink or curl-up. Then I guess they don't get enough flow on one side or underneath them and they start to rot away. Its happened to probably 6 of them. All other corals I can keep, just not these. I wonder what it is?

The XM bulbs look fine to me, but need actinics to get the various green mushrooms to pop. I just searched around and saw that most folks concluded they were a bright white bulb. I don't like too blue or yellow of a look. I forget the exact PAR, but they and the ballasts were a high combo.
Sorry, jer, I was off on vacation. I don't know why you would have problems with just leathers. Maybe just a source/condition problem?
