I've been having serious ammonia levels lately which i've tracked down to my tap water. Even when conditioned with Aquasafe or something like that, the ammonia levels are around .25 - .50. Worse still, the levels in my tank itself are off the chart, 5 to 7.5 8O
I've tried treating the tank with some ammonia de-tox, ,and doing water changes ever few days, but I just can't get the levels down. I'm amazed that my leopard spot puffer and blue spot puffer are still alive.
Today both fish looked really bad, so i pulled them out and put them in my 20gal long tank i usually use for letting newly mixed saltwater settle. ammonia in that tank is still .15 to .20 but much better than the main tank. I moved some LR
into that tank and both fish are looking much better.
As for my main tank, some background:
I inherited it from a friend that didn't want it. 46gal bowfront with UG filter and crushed coral substrate and fluval 203 canister.
I've since added much more LR
, better lighting, and a Magnum 350 canister with biowheels.
What i'm thinking of doing is tearing the tank down, using the 20gal tank to hold the LR
(and buckets if I have to) and getting the UG and crushed coral out of the tank and replacing it with a deep sand bed, then cycling the tank again.
Does this sound like a good idea or am i off my rocker? I've never been fond of the UG filter, and I figure this is a chance to get rid of it. I'm also planning on using RO
salt water from the local store for the new setup.
