Beat the heat
I type this semi-breathless as I inhale fumes from hell...
I was a little concerned about the effect of the hot weather on the ponds but I have to say, I needn't be. The terracotta pond does get warm but because of the massive surface area, it doesn't stay hot. Fish and plants are doing great. I removed 99% of the Callitriche stagnalis because it was losing its way and attracting a lot of algae. I've since replaced it with Duckweed which I very much like the look of - it hugs the margins in a very natural way.
The ground pond actually stays very cool, I think thanks to the ground itself and the depth of it, considering it doesn't have a large surface area ratio at all. I've not recorded temperatures above 22c. The fish are breeding and the plants have really gone to town!
I added an airstone to my widowsill pond which I have been running without any equipment for months until the hot weather came along. I've heard it helps with keeping temperatures down due to surface agitation. I think it has helped. This tank is in a South facing window so is most vulnerable!
It's also been subject to an aphid attack. My solution has been to just leave it be. I can win a war against aphids and so far there hasn't actually been too much damage. I've left some plants as sacrificial ones and that seems to have helped reduce the overall impact. The most noticeable effects are the curling of the leaves on the Lysimachia nummularia, the stagnation of the Houttuynia cordata and the occasional premature yellowing of a few leaves on the Oenanthe javanica.
Oh contraire...
Before keeping crystal shrimp in this pond, I researched the tried and true methods and came away thinking it might not actually happen for me. My setup went against all the advice, including from a very comprehensive guide here on UKAPS.
However, despite not following a fair few of the guides, the crystals
and cherry shrimp have had shrimplets in there. Same water, no tech, just plant power. One of the reasons I love this hobby is that we can push boundaries and find new ranges for both plant and livestock care.
The temperature ranges from 18-30 depending on weather (although it hasn't been through winter yet), the TDS is currently 88 (with evaporation) and both shrimps seem fine. Nitrate is almost always close to 0 unless I dose (which I do from time to time with TNC Complete). I feed them a few times a week with Fluval Bug Bites and top of with RO when the water evaporates.
I've also accepted that I now have a root carpet! I think it looks quite similar to dwarf hairgrass so mission accomplished! 😅
Apologies if this is incoherent 😅
