Hi Spirit HawkHave had another try with siphon went better lol! How do I put a pic on here? I need to reduce the ammonia level and I'm changing 1 percent of the water each day for a few days, as per instructions from staff at Pet store. Do I need to clean the filter each water change? Fish seem OK.
When you change water it helps to look at things this way.
If you have 1ppm of ammonia then 1% of a water change will remove 1% of the ammonia leaving you with .99ppm of ammonia. Your tank is going to produce it way faster than that.
Instead, I don't even bother with doing less than a 50% water change anymore. Each 50% watch change will reduce ammonia by half. Since a 0.25ppm ammonia level is considered safe for fish, that means you would need to make 2 50% water changes in a single day to make the water safe for your fish. It sounds like a lot of work, which it is. However, after the tank cycles then it's easy sailing from that point forward.
What size tank is this and what fish do you have?
Are you using the app or the website?
Some things I would recommend:
Reading this :
I just learned about cycling but I already have fish. What now?! - Aquarium Advice
(Super important) Buying this :
http://www.amazon.com/API-Freshwater-Master-Test-Kit/dp/B000255NCI
These test kits last a very very long time.
One of these will help with water changes immensely if you have anything larger than a 20g tank.

Lastly, if the LFS (Local fish Store) you went to really told you to change 1% of your water daily for an ammonia spike... please please don't ever listen to any advice they offer you again.
