Little experience as I just set up my 10 gallon last month. Now have a 30 gallon with no one problem yet. YOU DO NOT HAVE TO FOLLOW, THIS IS A LITTLE DIFFERENT THEN OTHER GUIDES.
Step 1:
Fully set-up aquarium with everything. (ie. Heater, Filter, Gravel, Decorations.) No live plants at this time.
Wait a couple days (2-3). Then add your live plants, and chemicals.( ie. Aquaclear, PlantGro, Cycle.)
Step 2:
Once everything has been running for about 5-7 days, test your levels.(pH & Nitrates). If they are good to go.
Step 3:
Go out and purchase your fish add them into the aquarium slowly, follow the correct procedure. And then keep an eye on the levels of the aquarium. Make sure your water temp is around 74-78 degrees before adding fish. ( inlease they are guppies or goldfish.)
Step 4:
Continue to keep an eye on water temp. pH levels, and nitrate levels to make sure all is running good.
I did this and my aquarium is working out amazing. Haven't lost a fish yet. My plants are growing so fast. And it is a beautiful set-up.!
Good Luck*thumbsups
