Yes, I connected through USB and used PLED. Did get the regular "usb connected" sound from Windows. Then I tried to upload the new time scheme or synchronize timing but all failed.

I was able to connect the TC420 and get it to work but it seems my TC420 USB function is DOA ... :( Will have to try again later.

Hi all I recently purchased a Twinstar RGB lighting kit, looks awesome and functions perfectly. I have found out that it is in fact dimmable with a simple in-line dimmer. However, I would like to create a sunrise / sunset effect using a TC420. Can anyone tell me how to do it? The Twinstar uses...

These are excellent indeed. The fact you can easily dim the LEDs is a huge advantage when battling algae. Also, the Superfish nano tanks are great. The standard filter pump is pretty powerful (I think it's like 200l/h for a 10 liter aquarium!), easily adjustable and water is filtered from the...

Hi mate HC is very sensitive to CO2, a fancy LED light won't fix that problem. If you want to grow a lush HC carpet, you're better off investing in a good CO2 setup :) Cheers Gilles

Excellent, thanks. I'll be getting one then! Cheers, Gilles

Question is: do Reuben & Ian have low light setup like ours or high light? @ Reuben: how did you lower intensity, are you using a dimmer?

Hi I have exactly the same problem: I'm setting up a 90cm low light - low CO2 aquarium and I'm interested in using the Grobeam 600. However, I'm not sure whether I should use the single or dual for a low light setup. Ian, you recommend using 2 for this size then? Cheers, Gilles

The tank is about 150x50x50cm so more like 400 liters. We'll be keeping crypts, java ferns and vallisneria. The problem is that my father is on a low budget (I can spend 100€ on plants and probably 50€ on equipment ...)

Hi guys I'm rescaping my dad's tank which will be a 500 liters non-CO2 aquarium. At this moment he has 2x 36w T8 (no reflectors). I know non-CO2 need low light to keep algae at bay but I have the impression that his current light setup will be too low for the plants? Any advice? Should I...

I'd buy a luminaire which can hold 2 T5's though, in case you want to upgrade to a high light tank. But it's always better to start with low-medium light ...

I use one 24w t5 over the same volume

Make sure the bulbs aren't "tandem-switched" before buying the Arcadia set. I used to have a Ferplast tank and if you removed one bulb the other one wouldn't work ...

Yes, but for such a low price I want to know how precise it is :D I know that there's a formula to calculate the PAR based on Lux so maybe they are using that (not so precise) formula instead of a "real" PAR meter.

Radik, are you able to obtain a professional PAR meter from someone and compare the results to those of the Seneye?

No one? I'm just wondering if this sudden change in lighting (I have 1 T5 atm for 6h) might cause an algae explosion. I know algae can easily adapt to sudden changes, easier than "normal" plants. Maybe I should buy some very easy plants for the 2xT5 lighting, get my CO2 and EI up and running as...

Wouldn't it be better to start with 6 hours of 1 T5 and then each week add one hour of extra T5? Then after a month I can start adding more hours. I really want to avoid algae ...

Thanks, will try that. Flow is even throughout the entire tank since I'm using a spraybar. CO2 bubbles can be seen at substrate level at the front (not at the back though due to heavier planting & stem plants). EI = 30-40ppm NO3, 3-4ppm PO4, 15ml Profito and 2ppm Fe dosed in 3 parts/week. I'll...

The tank is now without plants due to CO2 problems (broke my old system, new one arrived but I didn't have the right equipment etc ...). Should I start immediately with 2x24w and CO2 or will this cause algae problems?

Hi guys I have a 60x40x40cm tank, heavily planted, EI and pressurized CO2 with DC. I was using one 24w (I think) T5 with reflector (not sure about the quality of it, non-branded) but my Hemianthius Callitrichoides didn't want to grow at all and became leggy. My DC used to be lime green and I...
