I started this tank 3.5 weeks ago on Jun 6.
My equipment is:
Glass 37 gallon aquarium 30"x12"x22"
2x 65W 6700K compact fluorescent lights (On for 6 hours per day)
Pressurized CO2 with Milwaukee regulator
Nano Koralia powerhead (on for 30 min, off for 1 hour cycle when lights are on)
Flora and Fauna
5 neon tetras
10 rummynose tetras
8 amano shrimp
1 hillstream loach
1 crown tail betta
here is a picture of the tank on the first day. I was given an established tank by a friend, so the neon tetras were in the tank from day 1.
The HC started to pearl and fill in nicely for a week or so
Now, it looks like diatoms have taken over parts of my tank.
My water parameters today are
Phos - <0.1ppm
Fe- 0.25 ppm
CO2- 2.5 bubbles per second
I would appreciate advice on killing these diatoms. I have been trying manual removal and sucking it up during water changes.
I have dry fertilizers, but have not gotten into a good dosing schedule because I have been doing so many frequent small water changes to suck up diatoms.
I am thinking about doing a large water change tomorrow and starting to dose with the EI method. I am also thinking about increasing the light cycle because I am reading that diatoms don't like strong light.
