They are grow lights that give off a very pink light, like an even pinker version of the Salvinia Grolux or Arcadia Original tropical florescent bulbs. They grow plants well but look very unnatural over an aquarium. You would also need a heat sink (ideally with a fan) or they are a bit of a...

"Good enough", yep! That's pretty low light, but shade loving slow growers like Anubias and Java fern and most aquatic mosses would do fantastic. The reduced CO2 demand from the slower growth will make things easy and you should have relativity little algae growth. Remember the plants will...

That certainly is cheap! They are sold as "freshwater shrimp" in Pets@Home for about £3.75 each here - so just under $5 each :lol:.

Careful with that "ghost shrimp", it's Macrobrachium lanchesteri rather than Palaemonetes paludosus which is usually sold ghost shrimp in the US. Proper ghost shrimp are smaller with weaker arms and claws and don't have the striped markings. M.lanchesteri is far more common in the UK as it is...

There are many threads and discussions about this if you do a search on this forum, I'd highly recommend you read some :). Basically there is no advantage from changing the colour of tube, unless you just prefer the new colour. I generally don't recommend florescent bulbs specifically sold for...

12000lph! That's a big wavemaker lol, I take it you previously used that on a marine tank larger than 120l? The NeWave 1600 is excellent, I use some of them too :). Sent from my iPhone using Tapatalk

What pump was it lol? Dis you try aiming it at the surface from the bottom of the tank? :)

Minimum additional flow would be something like a standard 400lph powerhead, but the bigger the better, more margin for error when plants start to grow and obstructing flow. Proper circulation pumps like those used on marine tanks are much better, its unlikely it would be too powerful IMO...

For a 120 litre tank you would be looking at 1200lph turnover or more if your going by the 10x guideline. The Fluval 405 uses a pump rated at 1300lph, but you will lose a lot of this due to media in the filter, gunk in the pipes, pumping up a height etc., so really its probably only ~800lph...

Light at the substrate level will be fine for carpeting plants, provided you keep trimming up to stop the stem plants from shading too much. Some prefer higher light than others but they will just grow slower, if you want a fast carpet effect, you might be interested the dry start method :)...

Should be great for your tank :thumbup:. The colour of the bulbs makes no difference to plants, it's just about personal taste as to what you prefer. The white 10000k bulb gives nice crisp effect and accentuates greens to my eyes, while the "growth lux" bulb is a red/pink coloured tube like...

Specific brands/models do not matter, plants don't really care much between the different spectrums of bulbs, it's only that marketing that tried to tell you it matters. I think a single T8 tubes would be fine, I have 2 x 58W T8 on my 150x60x60 cm and this is great for low/medium light plants...

Brand new T5 luminaires can be bought for under £70 delivered as you said and yes, thats including tubes :). A couple of advantages to T5 luminaires IMO is they are so easy to repair even if they do brake out of warranty (just replace the ballast for about £10) is and you can change the colour...

Depends why you are worrying! :) If your worried that you've cut your lighting in half - you have. You had 48w of fluorescent bulbs (I think the boyu has T5HO) over the tank, and you have downgraded to 23w . On top of being half the power, you mention its a cfl "spotlight", which IME are...
