You didn't mention anything about your lighting and CO2 use. Your water parameters would be useful too if you are using a calibrated test kit.
Adding more Flourish products depends on your lighting and CO2 use. Excel can be used to help with carbon needs and to kill or slow down algae.
The link that I gave you to the Seachem calculator says that if you want to dose more, just enter more gallons and you will be getting a higher dose. There's a lot of good info those two threads. If you get a chance, read them all.
The Seachem calculator and their chart are made for basically low light to moderate light low maintenance tanks, but it is very easily modified.
If you have high light and CO2, you might want to up the dosing so that you are dosing 20 to 30 ppm of NO3 per week and around 3 ppm of PO4 per week or even switching to dry ferts and dosing these amounts.
A word of advice though. Seachem F. Nitrogen is made of ammonium and nitrate (urae in the form of an iminium salt and potassium nitrate). When you test the water with a nitrate test kit, you will basically be measuring half of what nitrogen is in the aquarium. So, you double the measured amount of nitrate to approximate the actual nitrate level. This comes from Post #2:

If you are using Flourish Nitrogen to add nitrogen you should only expect your Nitrate reading to be half of what is suggested above. The reason is that half of the Flourish Nitrogen in in the ammoniacal form which most plants prefer. |
From the F. Nitrogen bottle or the directions:
http://www.seachem.com/products/prod...hNitrogen.html
"To target a specific nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons*, n=desired nitrogen increase (if using a “nitrate equivalent” value for “n” then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example to raise 20 gallons* by 0.20 mg/L nitrogen you would use: 0.25*20*0.20=1 mL."
You use 0.05 in the formula instead of 0.25 because you want to find the "nitrate equivalent" with your test kit. As an example, you want to raise 190 liters of water or 50.2 US gallons of water by 7 ppm of NO3. The formula is 0.05vn=m
nitrate equivalent = 0.05
v = 190 liters ÷ 3.785 US gallons per liter = 50.2 US gallons
nitrate increase wanted is 7 ppm
m = mL of F. Nitrogen to add
Then: 0.05vn = 0.05 x 50.2 x 7 = 17.57 mL of F. Nitrogen can be added to increase NO3 levels in 190 liters of water by 7 ppm.
Does all this jabber help you some, willow52?

Fertilator use question 
lovely algae which prompted me to look into the fertilizers and balance...
I had two ottos, but I think one of them may still be in there..
