Lighting

Hi,
I've just been reading a post on here which explained that you need to supply 2-3watts per gallon of lighting to grow plants successfully.
I have a 13 gallon aquarium with just 15watts of lighting (1.15watts per Gallon) and my plants are growing fine :-)
I did have some Brown algae, so I added a reflecter to my newish bulb and upped the photo period. Added couple of Oto's and in just a few weeks the tank was as clean as a whistle :-)
Since then however I get a black hair like algae appearing on the Crypts and Swords.
I always thought most algae did best in high lighting? so what is going on in my tank?

Tank Details.

54l/13gallons
Internal filter capable of cleaning twice the water volume.

Ferts.

Seachem products used
Dosing 1mg excell daily, 1mg Iron daily, 2mg Pottasium weekly and 1mg of Comprehensive weekly. The root tabs I use are added monthly as recommended.

Plants.
2 Amazon Swords
2 Crypts
2 Anubias
Small bunch of Cabomba (not sure about the spelling)
2 Java Fern
6 small dwarf Sag
Bit of Java Moss.

Substrate is sand

Fish.

8 Cardinals
8 Harlequins
11 Rummy nose
3 Panda Corys
2 Endler Guppys
2 Otocinclus

Feeding.
Once daily, small pinch of micro Hikari pellets which gets eaten.
A few small catfish pellets for the Corys, which gets eaten.
Every few days a small pinch of Tetra Pro.
I alternate the pellets with with frozen Bloodworm and Daphnia.
Every 3 days I drop in an Algae wafer.


Lighting.
Single tube F8 'Dayglow' bulb 15watts.
I was running for 9hrs until the black hair algae appeared, so cut it down to 7hrs for the last 3 weeks. BHA keeps coming at me!

What do you think I'm doing wrong?

I'm going away for a week. I'm going to subdue the lights to 4hrs a day. The black hair algae is slowly turning white but is still active in places. Hopefully when I get back only a little Brown algae is present.
I'm going to leave the fish a Tetra Holiday block to munch on.

I am I doing the right thing? I leave in 3 days

One of the first things I learned in the hobby is that much of the information is either so wrong it is useless or it needed major rework to fit my tanks. From there, the feeling has grown to the point that I trust what I see in my tank far more than the generic advise that I often read. I find almost everything needs to be thought over, tried, and adjusted to fit.

One of those adjustment is not to worry about feeding if only gone for a week. The fish will do quite well. Many shippers stop feeding several days before shipping fish to reduce waste in the bags. healthy fish rarely starve but may clean the tank a bit closer.

Forget the watts per gallon rule, it's totally useless. Water depth is much more of a factor. Since you have a long tank you need less "watts per gallon," you don't need the extra brightness to reach the depth of your tank.

If you want hard calculations you need to look into lumens and lux and all that good stuff.

Don't know anything about BHA.
