Awesome
I took off the normal cf 23w bulb, and harvested about a gallon of chaeto.
Just installed the 3ow led and will report back in a week.
Excellent. I'll update with results (or lack thereof) of the h150.

Lol, I had to harvest today.. The bucket is with the two handfuls taken out.. Two buddies are starting their fuge and hopefully these will help them out.. Two weeks growth under sodium..
Wrong, wrong, wrong...I think that light will end up growing a lot of turf and other nuisance algae that will outcompete the chaeto for nutrients.![]()

Interesting discussion... from the reports I have seen on this board, HPS seems to be a winner. .
The take away should be more wattage grows more algea.
Yes spectrum plays a role as well.
But the perfect sprectrum in 10w CANNOT compete against 150W and a less then perfect spectrum
You cannot uncouple wattage from spectrum. 150 watts of 525 nm light certainly would be worse than 10 watts of 630 nm light. And the H150 is 40 watts (of what should be near-perfect spectrum for green algae), so we are not talking about a 10 watt CFL...
Keeping the chaeto moving would make it a non-issue. Although, I'd need to build a spray bar to do that.
I would certainly try to get it rotating. Either with a spray bar (the cheap route) or a gyre. (Haha, the idea of a gyre + a Kessil H160 to grow cheato is hilarious from a cost perspective). It'll both decrease trapped detritus and also make sure the far red is hitting the cheato uniformly (660 doesn't penetrate water very far).
That's the thing.. No one on here that I've seen really knows the right spectrum. I have talked to and with a few light mfg(including led) and they also have tested the spectrum that grows the best.. And it's not the common 5500k that most people are using.. And certainly not with common every day bulbs.. That was common, along with "red spectrum" being the other commonality..The take away should be more wattage grows more algea.

SO THE REAL TRICK here is matching your systems bio load to proper wattage while maximizing/fine tuning spectrum. This also means less wattage when using best spectrum/color

I do agree completely with the correct spectrum is key..
is what's in the water..
to try the sodium,
The rest, all low nm red from what I remember.. And this fixture is equivalent to 250 watts of light.
Mine doesn't tumble, never has..
Common knowledge among whom? Aquarists that use tiny bulbs? Those that can kill off cheato at the drop of a dime? The same people that say "a fuge is no good unless it's massive"? Being able to sustain a plant says just as much as the growth of the plant.. And you have to know something about plants to use very little nutrient and still maintain accelerated, or even regular growth.. Is not a basic thing that most can wrap their head around..5500-6500 is common knowledge. Changing to a different color will only effect growth slightly. It will not multiple growth
Changing wattage effects growth dramatically and can multiply growth in large amounts. Also note lum's is tied to wattage.
False.
I just grew a gallon in a week using a cheap old spiral 23w cf house light, that was old and of unknown spectrum
I said the opposite
Wattage is factually key. a 10w bulb with the best possible spectrum will not outgrow a 10k 175w MH light
I covered this fully.
Wattage needs to equal water quality.
A heavy feeder who doesn't change water much may need a 100w bulb.
A light feeder may exhaust the nutrients in the water in 3 weeks with a 27w bulb.
If your water is pristine, you mas kill chaeto due to lack of food and no lighting matters.
That's just it, high wattage bulbs like that work so well because the more wattage the faster the growth, combine with water quality, you will grow buckets.
So much wattage wasted on this weed lolguy could by some large water changes from electricity bill savings. Then the light would not be needed.
What I hate is being a light feeder, 6 years ago i do a few large water changes, and then it killed my chaeto not having any nutrients.
I'm trying again.
So true. Mine does not and grows fine now.
Power is not nearly everything
The tank you posted was full of hair algea in the display. Even in the sand
And having a dedicated fixture for growing cheato in the right spectrum with plenty of power is not a waste..
The quality of it says a ton
True, true...Haha. It is ludicrous when you think of it. I can imagine what people are thinking as they read this thread...150w hps, kessils, bml, gyre...lol [emoji38]
It's so damn good at exporting nutrients that you can't help but try to maximize growth at any cost.
Maybe I should have a solar tube installed over my fuge? Florida sun should be great for Chaeto. hahaha
After as it started to slide.

I see where you went wrong. There's no xenia.
Seriously though, old tanks are tough. The whole point of me growing Chaeto is to bring my 10 year old tank back after years and years of neglect. I also have "sandstone" under my rocks (both of which are probably loaded with phosphates).
It's getting there fast though. New r/o filters...found out my water has chloramines, and each water change was doing more harm than good. Lots of large sand vacuums. Removed the DSB in the fuge section of my sump. Bought a decent skimmer, newer dc pumps, new lights. Now growing Chaeto!
I now catch my teenage daughter and my girlfriend (of 18 years, lol) standing in front of it. The fish have names, and the tank is a member of the family again.
Your tank is like mine.
Every water change would give me GHA, I have rebuilt my RO station and went to dual membrane and all new filters hoping to stop this. Even added dual DI.
My DSB kept the tank clean and GHA free, but with age its stating to require more, so like you its chaeto time.
I really want to tear it down and flush the DSB and remove the sandstone.
was pricing rubbermaid stock tanks and thinking about acid washing my rocks.
