My aquarium plants just do not grow...or very..very..slowly....

100 gallon tank

4 HO T5 tubes above it
(now at 7 hours)

Just introduced Co2 a month ago
(trying to keep it above 25 ppm)

Seachem flourish
1 1/2 of recommended dosage

50% water change weekly



Amazon sword (grows a bit)
A. Reineckii. (tiny few new leaves...)

Staurogyne repens (kind of trying to grow..but not much)

Ludwigia glandulosa (very..very slow)

Vallisneria spiralis ( so..so)

The only plant which seems to grow ok in this tank is
Ludwigia repens
java moss..

Black and brown algae here and there
Green algae on glass..if I go beyond 8 hours of lights

It might be low nitrates....
Nitrate levels are very low....
0-5ppm

Just wanted to ask on this forum..thanks

You're doing big water changes with a really diluted fertilizer. I would recommend switching to mixing your own dry ferts. It's cheaper, especially since you need a high dose of a liquid fert (basically water) in such a large tank. Your low nitrates indicate a macronutrient shortage, and flourish contains really insignificant amounts of macros.

Great thank you...I was trying to look at some supply sources of dry fertilizers.....most of them in USA..shipping costs double the cost of those ferts..and they will not ship KNO3...or...Mg(NO3)2....over the border....there is guy in Winnipeg who sells smaller amounts of these dry fertilizer....but the amounts in his packages are like half of greenleaf aquariums ones?!.....maybe I should try some farmers around..haha

Try root tabs like @Niaa said.

I've heard great things about the Osmocote Root Tabs (for sale on amazon by the hundreds).

Also dose Flourish a day or two after doing the water change, the reason being that most dechlorinators also remove nutrients in the Flourish as well. The dechlorinators are still in effect until about a day after they are added, so add the Flourish after that so that the dechlorinator won't neutralize the Flourish.
