Hi Vadimshevchuk,

The purpose of the 50% water change weekly is to remove excess nutrients. Just because you are dosing 1/2 normal doesn't mean that you won't have excess nutrients, I would still do 50% weekly water changes. BTW, 50% weekly water changes help fish grow faster and larger as well!

Keep in mind that your 29 gallon tank is not really 29 gallons. After adding substrate and hardscape you probably have 20 - 25 gallons of water so dose accordingly. Here is the EI dosing schedule:

10- 20 Gallon Aquariums
+/- 1/8 tsp KNO3 (N) 3x a week
+/- 1/32 tsp KH2PO4 (P) 3x a week
+/- 1/4 tsp GH booster once a week(water change only)
+/- 1/32 tsp (2ml) Trace Elements 3x a week
50% weekly water change


20-40 Gallon Aquariums
+/- ¼ tsp KN03 3x a week
+/- 1/16 tsp KH2P04 3x a week
+/- 1/2 tsp GH booster once a week(water change only)
+/- 1/16 tsp (5ml) Trace Elements 3x a week
50% weekly water change

Hair algae could be a sign of too much light and GSA is typically a sign of too little phosphate. Hope this helps!

my light is only on for 6 hrs. i think i get it from dosing leaf zone cuz when i stop it dissapears

noob question... waht are trace elements?

Hi Vadimshevchuk,

Plants need three basic (macro) nutrients: Nitrogen (Nitrates);
Potassium; and Phosphorus

Plants also need other nutrients in smaller amounts (micro nutrients or trace elements) for proper growth: Iron, Magnesium, Maganese, zinc, copper, boron, Molybdenum, and calcium.

LOL.....aren't you glad you asked??!!

Vadimshevchuk

Yea! thanks seattle aquarist!

Vadimshevchuk

well i got and added the top three to my cart, what do i add for trace elements?

Vadimshevchuk

Load up with more plants, stems if you can. That will do more to get rid of your algae issues than ferts will.

Just order KH2PO4 and KNO3 (and CSM+B if you do not have anything else for micros). You'll get enough Potassium from those too and do not need to dose it separately. If your water is hard you should not need any GH Booster. And really do not need iron, there should be enough in the CSM+B but some people like to dose extra anyway.

Hi Vadimshevchuk,

I use the following: KNO3; K2SO4; KH2PO4; CSM+B; and Chelated Iron. A half a pound will probably last you a year or more, if it is available that way get it. I use small plastic bottles for my everyday needs and store my "extra" ferts in a cool, dry, location. You should not need a GH/DH booster if you have average or hard water.

Vadimshevchuk

alright thanks everyone. I am not excited for 50% water changes each week =/
