Wow that's pretty powerful, but tbh the wattage ratings seemed fairly high, I would be glad to turn it down, lower leccy but good water movement. In terms of co2 distribution these look like they would carry the CO2 to the substrate more efficiently. The actual models going to market are black, in my case it would suit, but not for everyone. I still struggle with plants getting covered in black GSA, I have upped phosphate dosing, light is subdued, but I was always insure about CO2 distribution bearing in mind my tank has a foot print of 8ft x 3ft. I wonder why they have not also marketed it for planted tanks, perhaps because it probably overkill at default levels plus it is the marine market that typically have £s.
Kirk, the tanks are still going, but very much more fern jungles, not so much aquascape masterpiece. Like I mentioned GSA is PITA in the big tank.
Thanks for the link Ollie.
