Honestly, I wish we could show your hubby what it's like with weird backgrounds and such

I have decided that if he keeps working weekends (flooring contractor) that I am going to paint the tank when he's at work.

I think it a bit unwise that he leave us (our three-year-old and myself) to our own devices on a weekend.

I've purchased the paint already. He hasn't noticed it sitting there, yet.

On the plus side, the snails and herms are doing a nice job of keeping the DT fairly clean

I've been messing with the MP10 settings and placement and am happy so far with the detritus situation

Where did you place the MP10s? I'm very interested in their placement, as I'm undecided over using them. Your tank is 12 inches longer and 5 inches taller, so if they work for you they should work for us.

Our 2 x MP10wES are centered about 30% from the front ( to center )
I had them about 25% down from the top ( to center ), and that was great for surface agitation, but not for detritus settling
Currently they are about 40% down
I set a mild wave ( less than 1/2" total travel ) in Short Pulse and am now running them in Nutrient Transport Mode @ 80% ( 10 of 12 LEDs )
This gives me a wave with about 1/4" travel
So far so good

If you do decide on a pair, you'd be able to turn them down low enough in that tank that I doubt you'd hear them

[Enigma]

Wow! I'm surprised you have them cranked up to 80%. That's 1260 gph for each pump (unless the change is logaritmic . . . which it might be). 1260x2/75=33.6 . . . so that's 33.6 times the tank volume per hour. 20 is recommended for SPS. Does that mean that the flow seems quite gentle?

[gregzz4]

It may seem like a lot of flow if you look at it that way. I'm sure I'll have to change things once I start adding softies and LPS
I'm only basing my settings right now on the amount of snail poop that settles on the sand
Until you make your mind up about buying some, you could ask around if someone would let you see their's running

They way mine are set right now, they pulse left - right - left - right
It's about a 3/4 second pulse each side, back and forth. This creates the wave. On the setting I'm currently using, they run this way for about 1/2hr or so, then there's a big surge. It's supposed to mix everything up and then flush it out the overflow

BTW, every tank is different, so where you start off with them placement-wise is up to you
I just raised mine back up closer to the top by about an inch as I didn't like the dust that was collecting on the surface in some areas
I'm still going to have to fool around with them until I'm happy

[Enigma]

I could be lookin' at it totally the wrong way. The change in the gph could be logarithmic, or the wave patterns could effect it. I'm trying to figure out if I could get away with a pair of MP40s (already thinking about the next tank ). I don't think I can twist the numbers in a way to convince myself that I could. In looking at the flow diagrams I prefer the 40.

Scape can have a huge impact on the flow, too.

[gregzz4]

I don't think you're lookin' at it the wrong way
Just keep in mind that it takes the pumps running full speed to acheive maximum flow

There's nothing wrong with you buying 40s if you're gonna use them for an upgrade later. You would just run them very low speed-wise on your 40b

Keep in mind ...
40s cost a fair bit more and cost lots more for replacement and repair parts
Good thing about them is the wet-side parts are available separately

[gregzz4]

Nothing exciting lately

Just did a WC on the curing LR
I had the rock in a covered rubbermaid while cleaning out the main one and decided to inspect it all again
Found another fireworm and, stupid me, grabbed it with my bare fingers
Looks like all my years of manual labor has toughened my skin enough to protect me
I broke the bugger, so I took the rock to the sink. I turkey-basted hot water into the hole a bunch of times and the worm oozed some black stuff
I broke away some rock around the hole and, when I grabbed it with tweezers, it came right out
