Slash Posted February 7, 2021 Share Posted February 7, 2021 When I started my 29 Gallon tank at the end of the summer I got a Cryptocoryne Wendtii red. It really became one of my favorite plants, my Pygmy Corydoras love resting in it’s leaves and my Kuhli Loaches also rest near the bottom of it, hiding in the plant. I have small rounded river stones over some special plant eco complete substrate. Recently I made a few changes in my aquarium and suddenly the Crypt started melting like crazy. It’s been depressing to see how bad it has suddenly gotten compared to how vibrant and lush it used to be, Note it’s a red Wendettii but is mostly green, that’s because I don’t dose Easy Iron, just Easy Green. I had decided it wasn’t worth adding iron for just that plant, and my understanding was that the plant would be fine it would just be mainly green instead of red if it didn’t get enough iron. -Past parameters (About 3 weeks ago): Ammonia: 0 Nitrites: 0 Nitrates: 0 PH: 7 KH: 40 GH: 60 -Current parameters (Today): Ammonia: 0 Nitrites: 0 Nitrates: 0 PH: 7 KH: 0 GH: 30 The attached pictures show the progression: 1. After first planting in the end of the summer of 2020, 2. Two to three months later 3. Sometime after I added a sandbed near it and it started to melt, 4. Today after I removed all the leaves that melted off. That’s some Val grass on the right of it. I have had an algae problem for a while and I’m finally getting some Easy Carbon to add once the shipment arrives. (Half dosage so as to not kill the Val) NOW - Why is my Crypt melting? I think it’s because of the addition of some sand substrate but here are some possible culprits: -I recently dosed Fritz Paracleanse in the tank then did a 25% water change afterwards. None of the fish looked or seemed sick, I just did it as a precaution. -Fish overuse it. I have pygmy corydoras and kuhli loaches, a huge mystery snail that is always getting on it and pushing the leaves down with its weight. The Kuhli loaches may sometimes disrupt the top parts of the roots. -I haven’t added any new Easy Root Tabs in over 4 months. Now the main culprit and probably only culprit is the new sand substrate, my KH is 0, down from 40. The Ph is still 7 though. I got some Habrosus Corydoras a few weeks back and felt they would prefer some sand substrate to rummage for food in, and they do sure love it! I only added a small patch. I would have added it in the corner where the Crypt is but I didn’t want to disturb it! So I added it just by it in a small flat area that was clear of plants.. The sand I got is “CaribSea Super Naturals Moonlight Freshwater Sand” I see now that it said on the bag that this sand was a “Perfect way to detoxify metals” I’m wondering if that is what lead to the drop in the KH? Any plant experts would have any guesses or think that is definitely what happened? Will it ever recover? Should I add crushed coral or wondershell now so i don’t get a sudden PH drop?
