High Nitrate problem.
I think i talked about this in the past, but i am not able to find my old post or did i resolve the problem.
i am having High Nitrate problem on my new tank that I set up.
There is no live stock in the tank other than snails and one assassin snail. I am doing a water change every alternate day.
These are the Nitrate readings i see after like 80-90% water change
i see zero right after water change.
i see 20ppm nitrate in less than 3 hrs.
In 12 hrs it goes to 80ppm.
before next water change (which is every alternate day)nitrates are at 80+ppm.
i have tried 80% water change, then i thought i might be doing a full reset of all water parameters by doing so and starred trying 50% water change every alternate day. Still back to square one.
Tank is 30g and I am dosing using EI method.
have pressurized co2 with around 27-29 bubbles per 10 seconds.(cant get the exact count). so i would say 3 bps.
I checked my tap water and the nitrate is zero.
So this is for sure a problem inside my tank.
Tank is just 4 weeks old. have HC carpet growing on one side and Dwarf hair grass in foreground.
Have no problem with algae other than slight hair algae.
I am able to reach like 70% of my tank gravel to do a decent vacuum, but the 30% is out of reach.
Running a eheim canister and it was from old established tank. Cleaned it on the day i set up the tank and haven't cleaned it yet.
Running 2 60W equivalent CFL and 1 40W equivalent.
drop checker is slightly below greenish.
But it is not blue at the peak hours.
Ammonia is zero all the time. I guess the canister is holding pretty good. ph is around 7 to 7.2
What am i doing wrong?
I like the way plants are progressing, but i am tired of just looking at fishless tank :'(
Change to post for dosing questions:
EI dosing with macro and micro stock solution with GLA ferts.
