@mysiak:
I’ve seen the helialux but in my opinion, a Rio180 is too small to invest so much money in.. 😛
Since I got the aquarium from 2nd hand website, the light would cost me 3times more than the aquarium ahah
But I don’t deny that it would be an amazing thing to have, I woud just prefer to use it on a bigger tank, maybe when I upgrade to a Rio 400? 😄

But what do you think of the classic LED tubes? Since I’m at 90W T5, would it change something if I change to 46W LED but from the multilux range? According to Tropica’s label, Thaianums need 0.25W/L.

Also, I’m considering the Roots Sticks from EasyLife, you said you use them, are you satisfied with the results? Are you breaking the sticks to spead around a plant’s roots?

I agree but here we talk pure Aquascaping, if I were to have a nicely aquascaped tank with proper soil and a nice variety of plants, I wouldn't mind exploding the budget but the aim here is to have a nice looking fishtank without breaking the piggy bank.. :P

Browsing on Juwel website, I found this: "The MultiLux LED features a higher light intensity while saving up to 50 % of energy compared to conventional T5 technology. Further advantages of the MultiLux LED include a longer service life of the LED tubes, and durable light quality compared to T5 fluorescent tubes."
Does it mean that for my plants it will still be too itense light that it would keep "burning" them? And that in the end the only difference would be money saving on tubes replacement and energy bills?

@Luigi - if you want to use MultiLux LED tubes, you must buy MultiLex LED light unit/fixture. If I'm not mistaken, price for MultiLux and Helialux (old version) is the same. So you won't save any money in this regard. Light output of T5 and MultiLux LED lights will be roughly the same as well, so you won't "fix" anything. If your only goal is to make lights dimmer, buy universal T5 reflectors and turn them upside down so they partially block the tubes. This will cost you a very little money and it's a "no hassle" solution.

EasyLife root sticks are IMHO very good. I break them in half and stick them into the substrate around big plants every ~3 months. Plant growth is a good indicator, once I notice extremely slow growth of Echinodorus or Cryptocorynes, I add sticks.

Hi mysiak,
I think I will try out your idea of using the reflectors upside down!
Do you think it could be usefull to drill the reflectors so I'm still letting some light pass through? I'm thinking of maybe doing a few small holes 2-3mm here and there.
Don't you think that if I'm not drilling, all the light will be reflected to the top and I would lose most brightness? Or it will just then partially fall back into the aquarium?
Would you buy full length reflectors or shorter ones?
Thanks for your feedback,
Luigi

Mounting them literally upside down will be probably an overkill, but I would try mounting them sideways, blocking maybe 50% of the tubes and redirecting the rest of the light towards back or front of the tank. Just turn the reflectors around until you find a desired light level in the tank. This way you won't have to play with drilling. Having covered 100% length of the tubes will give you more control, but you will be probably limited to plastic Juwel reflectors as they have non standard length of tubes. Metal reflectors can be bent to almost any shape, so you could have stronger light in the front part of the tank, low in the back etc.

You could still use floating plants in the corners, they naturally gather there (and they will lower your nitrates, which is a nice bonus in a cichlids tank). Also you can keep them in place with fishing line or airline tube. Many options out there

Btw. if you use reflectors in the "normal" way, you can easily gain about 50% more of light if you ever decide to.

If you put a single layer of window screen (insect screen) between the light and the tank, you will reduce the light intensity by about 40%. Add a second layer and you reduce the light by a total of 64%. This is true for the gray fiberglas screen I bought at Home Depot. I don't know if the screen you could buy would be the same, but it would probably be similar.

Good idea. Windows screen tint film (used mostly for car windows) would work as well and there are several strengths available. Those can be bought from eBay very cheap and can be stacked as well.

I wouldn't use film for this purpose, because it changes the spectrum of the light that gets through the film. https://www.homedepot.com/p/Saint-Go...41-M/100245818 is what I tested.

Those films should be neutral density types (they filter all visible wavelengths equally), but obviously doesn't have to be 100% true and it's hard to confirm without a spectroscope. I use them to dim my digital bedside clock..

Just curious - how did you attach the insect screen to the lights? Do you happen to have a photo? In a Juwel tank it would require either wrapping the tubes directly which I suppose can be dangerous due to overheating, or a bit of glue/silicone to hold the mesh in place.
