May have killed bio filter - what to do?
This past week I was away on vacation for the first time since setting up my tank, at some point my intake pipe got completely clogged and no water was making it to the canister filter. The filter itself was also devoid of water - I'm guessing the CO2 pressure in my reactor played a role in that meaning filter media was in a CO2 rich environment.
After fixing the issue with the filter the tank ran ~24 hours with no other changes then next day I did a 2/3rds water change. Before this I wasn't even thinking about damage to the biofilter until I saw the ammonia levels after the water change were at .25 to .5 (previously always zero), nitrite 0, nitrates ~20ppm.
If the tank is no longer cycled what are some alternatives to speed it up or how long should I give it to see if it will reestablish on its own? Found one article that suggested doing small (~10%) water changes daily till tank gets cycled again.
I'm counting my blessings at this point as I haven't lost any life stock yet (including CRS) and the filter still works even after running dry for unknown period of time +1 to Eheim.
Any suggestions on what to do next would be great (and yes have already fixed intake pipe so this won't happen again).
