I’ve been working really hard for the last weeks to get the co2 system running perfectly. Ista co2
reactor was a nightmare to figure out. Lots of issues but the main problem was that my 400 GPH return pump was not strong enough. I replaced it with a 800 GPH pump that I had on hand. It’s noisy but acceptable. Maybe I’ll get a DC one later as need this one sometimes for moving water.
Lots of noise issue as well so I removed the top impeller (kept the other one so the central part would hold in place) and filled the container with small ceramic biomedia. The goal was to dissolve the co2 without the noisy moving parts. After lots of adjustments and testing, it works better that the original one as far as co2 injection goes. For cutting bubbles, it works 80% as well but the bubbles are few and very tiny. Only noticeable if you look very close.
I could try to get rid of them by adding coarse sponge to the Ista but it would be a real pita and take a long time. I’m tired of fiddling with it and it’s going to stay how it is. I’m satisfied for now.
Fish are doing well. The festivum is very shy and only starting to come out a bit. He ate with the others yesterday for the fist time but sudden movements will send him flying away. I went back to my twice a day feeding routine and I alternate frozen and pellets, as I realize feeding frozen to 40 fish twice a day will require a whole different budget…
A few days ago I noticed the royal acara had a few
ich spots so I turned on the UV. I waited 2 days but he was starting to have more (7-8 spots instead of 3-4) so I researched medications that wouldn’t stain the
silicone in the tank but could not find any that was available in Canada. So I called my LFS and they recommended Korden Ick-attack that was a natural, non-staining product.
Spots were significantly less the day after the first treatment and there are none today, after the second treatment. I’ll treat 3 more days as per instructions and keep the UV on for month.
TDS was 149 today (starting TDS was 106 but I’m dosing Thrive + now) so I measured
nitrates and they are still 1-2 ppm. I’m surprised they are staying low with all the heavy feeding but I guess the 6.7% daily WC is doing its job.
I’m happy to finally be catching a break with the co2 system and hoping it stays this way.
Now I need to figure out the plants…
