620T LED Conversion

Recommended Posts

Looking at using 2 of these to replace the twin flouros in the hood of my Aqua One 620T tank.

http://www.ebay.com.au/itm/2X-LED-Flood-Light-30W-220V-warm-White-Wash-Light-Outdoor-Lighting-/201438662153?

Looks like I can connect them to switch individually and I can fit them neatly in the original hood after I strip all the old flouro stuff out.

Cool white, 6-6500k.

Any thoughts or suggestions?

Woah. That's way too much light for that size of tank.

Maybe one would be a better idea.

OK, my mistake I guess.

What would you suggest if I want to use 2 lights? 

The original flouros in this tank are 18w, but are reported to be too weak for plant growth, as well as notorious for bulb failure.

These lights come in 10 and 20w as well, maybe 2x 20w?

I would expect that while LED's are said to be brighter per watt than flouros, there'll be some "optimism" in the ratings given on ebay LEDs.

I should point out that while the tank is only 60cm wide, it is about 70cm deep.

I have an electrical/instrument license and can wire anything. I'd like to have 2 lights so as to use both switches and for versatility of how I light the tank.

I'm reading that cool white at 6000-6500k are the way to go for plant growth/freshwater?

I'd really appreciate some advice here, as I want to get this tank set up asap.

Cheers again

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.

      It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

      I believe these to be very rare in Australia so you may even consider making it a longer term plan and produce your own by starting with the best CRS you can get as that is where the pure lines started! Depends how patient and interested in the project you are, but would save money as well? If I recall correctly it takes from 8 generations of selective breeding? They sell them at micro aquatic shop but do not ship to Western Australia, but that means they are available in Australia. https://microaquaticshop.com.au/products/pure-red-line-grade-ss-shrimp Good luck and just maybe smeone on here may point you in the right direction or be able to supply you with some.
