Well, here's the deal. My mother and I bought this tank for my father for a Christmas gift (2003). He didn't do the best of job of upkeep on the tank and it looked terrible last October. Since I live next door to them, I took over.
The tank's base was CC
and the water was very green/yellow. Every weekend for several months I did a 50% water change, but within 2 days the water would be green again. The PH
/Ammonia/Nitrite levels were always fine, but the Nitrate and Phosphate were a little high. I came to the conclusion that the CC
was the culprit.
Two and a half weeks ago I decided to switch to a LS
base. I put all the fish in a holding-tank (Rubbermaid baby!) and drained the tank, removed the CC
. I left the water that was in the Canister filter as is, didn't clean it. I added 40lbs LS
and 10lbs of cleaned play sand purchased from my LFS
. I also added two 3lb LRs. Filled the tank and let it sit for about 6 hours. After checking the levels, everything was perfect, so I re-introduced the fish. I also added a skimmer.
I think my Mandarian Dragonette died to due being attacked and starvation because I didn't see him eating as much as he did when I had CC
. Feeding habits are identical.
I also think the rise in Ammonia is a mini-cycle. It did this after about the 3rd day of the new LS
base. As of yesterday evening (Sunday), here are my levels:
If the ammonia isn't back to 0 by this evening, I'll do a 20% water change.
