Hi all
I have a ATI sunpower unit that holds 8x54w tubes, two of which are actinic
I intend to change all the bulbs that are currently in place as they were used for a marine setup ... I have trawled the net for advice on combinations of tubes to use for a high spec planted tank but most advice relates to marine setups

The information I did find recommended aqua flora tubes combined with midday 6000 ..and some used purple, blue specials, and a 10,000k bulb ....

I wondered if anyone has any advice on the best combination to use for both plants and fish

Are the tubes mentioned above a good mix? And how many of each would people recommend
As a guide I wrote down the following:
1 blue special
2 purple
3 aqua flora
4 midday 6000
5 midday 6000
6 aqua flora
7 10,000k
8 blue special

Obviously these were just my first thoughts so any help would be much appreciated
Cheers
Mike

The color temperatures of the bulbs has nothing to do with how much light you will get from that 8 bulb light. I suggest starting by using only 2 of the bulbs, or, at most 4 of them - the front two and the back two, to keep them well separated. That could still be more light than you can live with.

i have that same tank (120g) and you have way too much light. i just bought a new ATI 6x54 to replace my 8x54 tek that i used for 7 years. with good reflectors (both tek and ati have them) you can get away with only 4 bulbs. and even then you need good co2 and ferts or its algae ville. i bought the ati for its dimming capability and timer functions. even suspended 8-12 inches or more its alot of light at 100%. run 4 bulbs and see if you get the results you want. all 8 is way too much for fw planted IME.

Agreed.

I run 2x54 of T5HO over my low tech 90gal (tank on the right in my signature). And it's on the cusp of needing CO2.

Hi all
Thanks for the input .... I will probably go with using 4 tubes
.. and look at using two aquaflora and two midday till I can manage to replace the unit with a more specific one for a planted tank
