API Co2 Booster and (my) crypt(s)

Well, I believe its been three days with the API Co2 Booster.

Overall, its not a bad product, but the Crypt that I purchased at Petco is obviously not tolerant of it.

Within 4hrs of doing the recommended dosage the top 1" of a mature leaf was eaten away. Large necrotic spots had developed on several older leaves where potassium deficiency had made holes.

This morning I had noticed some crypt melt on some of the older leaves and started thinking and researching about what might have been going on. I had considered the API co2 Booster, but hadn't made any decisions.

I performed a 15% wc about 4 hrs ago to clean out powerheads that had been clogged and afterwards dosed 2ppm potassium and 3ml API Co2 Booster. Now the crypt is showing clear signs of melting I have concluded that it was the API Co2 Booster.

I will cease using this product on this and the 29g since they both have the same species of crypt.

BTW, I had used Seachem Excel and did not notice any melting of these crypts, but I also did not dose the recommended dose daily (I dosed 3x dosage after wc).

I don't think that product, or Excel, will harm Crypts. And, I don't recall reading any reports of such damage caused by Excel. Perhaps when you dosed the API CO2 Booster it helped increase the Crypt growth rate, but there wasn't enough other nutrients to support that growth rate, so the plant sacrificed some older leaves. (Just speculating.) I have used Excel with crypts and they did fine. CO2 Booster is almost the same stuff, so it should give the same result for the same dosing.

+1 ... I have a tank full of crypts (40+ plants) and I dose excel all the time. None of my crypts melted.

My Crypts stopped melting when I stopped dosing Excel... Pressurized CO2 FTW.

I have dosed Excel as much as 3x the recommended dosage without adverse affects on this species of crypts.

I dosed the recommended dose of API Co2 Booster yesterday and within hours it had destroyed several leaves. All of the leaves that melted started to melt where a potassium deficiency had created a hole. It appears the that the Co2 Booster got into the leaf and melted it.

Other leaves are completely unaffected, but those with holes show clear damage that spread well beyond the potassium hole within just a few hours.

Excel and crypt melt is a hit and miss case. It depends.... Anyway, crypt can melt for many reasons. I have my giant Wendti red melted couple of leaves just because I have uprooted a giant Amazon sword near it. I have been dosing excel using the recommended dosage for over a week without the initial dosage. I am getting some melt here and there. However, I am getting massive new growth as well. Those are doing fine.
