More Lighting

[hollanda88]

I have jsut installed another 15W light (T8) to my 90L tank bring the total now to 3 15W t8 bulbs. I have done this because i thought the lighting wasn't great. The leaven on the plants were developing holes in them and black dots which were turning into holes.

Do you think the extra lighting will help?

I do 50% water changes weekly, have a fluval u3 and 305 totaling 1500L per hour, i dose feproll about weekly

sounds like a nutrient defficiency. The extra lighting will mean the plants will need even more now! I dont think ferropol contains N or P so upgrading to a better fert like TPN+ or seachem flourish would be a good start. Then, dose more often.
