Hi.
Are some snails more reactive to CO2 than others?
I have 2 rabbit snails, and 2 horned nerite snails. On Monday I bought 2 red onion snails and 2 striped nerites. The striped nerites struggled with the CO2 and died. I have been calculating the CO2 levels by D/C and KH/PH measurements off of the chart. Admittedly I am just trying to find the right setting but the day before yesterday I kept the CO2 no higher than 22.6ppm, (KH 3, PH 6.6, (down from PH 7.7 before CO2 was turned on)). One snail died that day. Yesterday I was caught out for an hour as I hadn't realized the KH had risen to 4 overnight from the rocks in the tank I presume and the ph dropped to 6.5 so CO2 was 37.9 for an hour until I realized the problem.
The thing that I'm struggling with is my KH test only goes up in steps of 1. Is there a more accurate KH test out there as otherwise, you could be way out on the CO2 levels and not know it. My D/C always seems to be lime green and not yellow so I am not finding that much help. My plan is to keep it around 6.7-8 PH today which would put me in the 23.9-19 ppm range hopefully.
Either way are some snails more reactive or could it be that they came from a non-CO2 tank and needed more time to adjust? All of my other snails seem to be ok.
I know cheap test kits are frowned upon but I've included the details anyway. (NT labs test kit).
Tank 200L
4 weeks old although FX6 filter has been running for 2 months, (4 weeks with plants and no substrate).
Ammonia/Nitrite 0
Nitrate, 0ish. Pretty much running clear on the test with the very slightest pink hue if you strain your eyes.
KH 3-4
Tap/tank water 7.7ph
Dennerle Scapers soil
Mini Landscape Rocks
Temperature 23 degrees C
EI fertz, 40ml macro/micro on alternate days basic APF mix for the moment.
4ml of Glute
Only have the 6 snails which are mentioned above and tiny bladder snail invaders.
The only algae issue so far was some green thread algae spirogyra on some high up weeping moss. I removed the moss so I could blackout and nutrient starve it separately and that is all cleared up now and ready to put back in.
Lights are 2x 38w T5. for 6 hrs per day, for the moment. The front one has a reflector on it as my carpet plants needed more light.
Water changes have been 50% every other day for the last 2 weeks and every day before that.
Any tips welcome!
Thanks
Dave
