Even though just an FO
tank, good water flow is still very important. With the XP I'm assuming there was no sump? If so, was the tank covered with a glass lid?
issues are often caused by improper gas exchange and insufficient GPH
moreso than chem deficiencies. I PH
and the filstar will not come close. The XP2 runs at 300 GPH
when emptyand once media is placed in it the flow will be cut by about 1/3. What kind of PH
What I would suggest is once you get the LR
in the tank, completely recycle it as it where a new tank. You can read up on fishless cycling in the articles section
. The LR
will cause a small spike in the readings but unless uncured will not be enough to properly fuel a cycle. Once the tank is properly cycled and with the addition of the LR
, you should have less NO3
problems. You may also wish to lose the sponge filter pads in the canister. They can reduce the flow a fair amount and the LR
should handle your bio filtration. I use mine mainly for carbon and a poly filter.
How was the skimmer performing and how often did you rinse the media in the Filstar?
