Gutter guard. TM.


In front of the weir. Worked awesome on the 50G setup. Not 100% sure how I'll be attaching it yet...

That's sweeeeeet. Thanks for all the photo updates. I'm really looking forward to seeing this come together in its final location.

Tx! Picking up the last plumbing bits on the way home tonight, water test tonight, book the move tonight. Woot. This weekend is Thanksgiving, so really hoping to get it moved Thursday.

Due to the weight of the stand and the ext.overflow making that end of the tank awkward, this will require four of us.

Oh, side note...this is the LED fixture we'll probably be getting...

The 72" model with the optional dimmer. Not cheap, but should pay for itself within a few years compared to running dual 2-bulb 36" T5-HO fixtures.

I talked to one of the guys from buildmyled.com at MACNA and he seemed to be a pretty straightforward and helpful guy. Meaning he actually took the time to talk to me when I mentioned planted tanks at a reef keeper's convention.

Yeah, not only have I yet to run across a legitimate negative review (usually pebkac), but saw a positive review indicating favourable shipping to Canada. If they could do the combined duties/shipping fees, I'd buy it today!

After more research might even go to the 13000k unit over 10000k. Hm.

Why would you choose to go that blue?

Pretty fishies. PAR levels are still pretty much the same as the 10000k, so plant growth should not be affected...does that sound right?

Filling up for the final test...


Rawr


Siphon break
After minor adjustment, it is silent.


No leaks!! Gave it a good five minutes, nary a drop!


Why you glue fittings


Used the adhesive silicone this time


Operating water level in ExOF


Sump seal fix part 1



A few buddies are coming over tomorrow night to help move it all downstairs!


Hm...it's full of water right now... ruh roh shaggy

Have you ran the system with the full siphon open to the surface? Generally you want it downward facing AND a few inches under the waters surface. If not, given decent flow, you'll be prone to a 'slurp'...... 'slurp' ..... sound.

PS: why not use unions under the bulkheads if you're concerned about needing to move the system?

fishyboy, yep, system has been run like that - no noise - and there is a problem with 'a few inches'. This is a 125G tank...a few inches = 10-20 gallons being sent, unfiltered, back down the returns, into the pumps, and into the sump.

Also, the concern was not about moving, but about re-using the bulkheads in future. Kind of a silly point on my behalf, since it'd be pretty terrible practice to re-use a key failure point in the system - especially since the cost, relative to the risk, was so low.

More reading on the BML site articles confirms that PAR is PAR, colour spectrum does not affect plant growth as long as the right PAR levels are present. So 10k, 13k, same thing. I think there's a 5-10PAR difference between those two at 18-24", and when the lower of the two values is still 70-80PAR...haha, we good.

List of stuff still left to do, fabrication-wise:
  1. Sump: cut rubber sheet to fit around drains
  2. Sump: duct tape for seams
  3. Stand: paint/trim the 2x6 hose holder
  4. Return: figure out best way to secure piping
  5. Drains: lid for external overflow box
  6. Stand: electrical...ummm....cut hole for wiring?

Crazy,

Color rating doesn't affect the amount of growth as long as PAR is equal. It does, however, affect growth habit in my experience. Blue light tends to encourage leggier growth and red light tends to encourage more compact, bushier, growth. In the end it's a personal aesthetic choice and judgement call. As long as the plants are growing, the fish look good, and you're happy, who cares?!

But PRETTY FISHIES! ...

Hm...compact and bushy is good. Got any sources on that? That's a new line of thought I've not heard yet.

I don't have any sources I can link online. I'd send you a couple of my botany/plant physiology books, but that would be expensive. The general premise is that during early seasons/germination time more blue light gets to the ground and plants see that as a clue to grow up. Come late spring and summer the angle of the sun to the earth is more direct so a higher proportion of red light hits the plants. This is the season they grow "out", put on mass, and flower/make fruit. This is mostly a temperate zone phenomenon. In the tropics more blue light passes through the canopy so anything growing in the understory gets hit with blue light which encourages them to grow up toward the sun so they can get full light. Similar things can be seen in clear/slightly turbid water.

You could probably encourage bushier growth (relative to the light) with trimming too.
