I started a new planted tank a couple weeks ago. Its my first time using aquasoil as a substrate. Since the first day it turned my water a murky yellow. I had been doing daily 50% water changes so I could at least see the back wall and so some light could reach the plants. I went out of town for 4 days this weekend and came back to a completely yellow tank, almost an orange tint. I couldn't even see an inch through the water. So I did a 100% water change and its back to its usual yellow color.

I figured it was the ammonia leeching from the AS but its now been 2 weeks and still just as yellow as the first day. The ammonia is reading 1ppm and nitrite is up to 4ppm. Almost all my HC has wilted away, probably from lack of light. However, the Riccia, HM, and dwarf hairgrass seem to be surviving.

Is this just the usual cycle or should I be doing something to take the yellow away? Will the color go away once the cycle completes? I have some purigen i intend on using once the cycle completes.

Yeah it's the tannins in the aquasoil. Mine was cloudy and yellow for a while. Just keeping doing wc's and the purigen will definitely help but you'll be recharging that sucker like crazy. I had to recharge mine about once a week when iwas using I to get of tannins from the AS and driftwood.

I'm also using aquasoil but I'm doing water changes every two days. This is my second week so far but I realized that the water is becoming less yellow two weeks later. Don't get me wrong, the water still gets a light yellow color but not as dark as the first week. I'll be using purigen the start of my third week for about a month.

Just keep up with the water changes and from what I was told in about a month or so it should clear up.

Well water is stilllllll yellow. Does everybody not have this problem. Is it just based on the citys water or the particular batch of aquasoil? I have seen several peoples new tanks on here started with aquasoil and their water is clear from day 1.

Also, I took the purigen pouch out of the filter. I noticed that the pH had gone up to 7.4 and before the purigen it was 6.5. Did the purigen cause this? I did bleach it once but I let is sit in water w/ seachem pH natural regulator for a day. Will the pH eventually go back down? I removed the purigen like 5 days ago but still get a pH reading of 7.4.

my 120g took more than 6-months to lose that yellow tinge. dont use purigen, cram your filter with carbon to help remove the color. also keep doing the 50% water changes. i thought my tank would never be clear, but does happen, just be patient. assuming your using AS 1, AS2 doesnt color the water at all IME. if its AS2, you have another issue instead of tannins.

If I don't use the purigen I still get a little hint of yellow in my tank by the end of the week. Just keep up with your weekly wc's (if your dosing and cycled) and keep up with the purigen and or carbon. AS is supreme in the way it grows plants but it's packed with peat so it'll take a while to get the tannins and staining out. Buy yourself another purigen pouch to swap in your filter while the is recharging.
