Thanks for the info. I've got a lot to think through and adjustments to make.
the Hob filter is indeed there for flow. I'm not convinced theres enuf circulation with out it. The spray bar moves the surface a bit, but the hob gives me more. All the plants seem to sway lightly in the current.
Do I add something inline at the end of the co2 diffuser?
That's my diffuser, the white mess on the right. The black mess on the left is a UV sterilizer that I removed, and never used.
Water enters the top post filter, then out and up to the tank. The filter is a fluval 405.
Reading aquaticfan & willknowitalls comments, I realize how flawed my diffuser is. The placement of the probe is shown there too. The probe is 3" above the co2 injection point. That runs at about 1.5 bps.
The thing is, I don't understand e correlation between co2 & ph.
I understand st is drop checker continuously shows ph visually and responds to changes quickly, but what's the point, might I suddenly dump extra co2 to control a spike in ph? what do I do with the data?
I use API mater test kit (ph, ammonia, nitrate & nitrite.) Liquid test kit from 5ml water samples. No test strips. I check before a water change.
There was a small spike in nitrates of 7-8ppm nitrate on 2/17. I had added 8 fish and 8 snails on 2/16. At that time the tank was 6 week old, I had 3 soldiers (tetras) for 2 weeks prior.
I do use flourish.
Tell me more about these ferts? Where do I get em? How do I test nutrients in the tank?
How do you termine how much co2 is in the water?
The light is a Deep Blue, solarmax ho model. 2- 36" t5ho bulbs.
I don't introduce new fish correctly at all. I really did kill those cardinals, it wasnt the LFS fault at all. Ill have let them keep the money.
I don't turn the co2 off at night. I'd expect the ph controller to turn off the co2 if it reached 6.8ph, the set point. That thing wa calibrated the 1st week of feb.
Should that be on a timer too?
I'll turn off the co2' and see if it changes the co2 as suggested. Man I hope I don't have to abandon that reactor. Poooooop.
Thanks a lot for he help.
