Quite a nice find, can never find any for sale when I have the space for them.

Chasing PH can be quite tiring, if you're not trying to use some sort of additive to your water when you do water changes or something similar to lower the PH, you can add some organic matter that will lower the PH slightly. Things like botanicals, wood, organic based substrate all lower your PH to some degree and if you don't do massive water changes frequently you could lower it a bit. On a side note, I'm not familiar with your tank and what its used for so you might not really need to change the PH.

such high PH isn't great for most plants, but as mentioned if you're looking for iron supplaments look for DPTA as that would be the cheapest option you have that still somewhat works at that PH. EDDHA is the best option for your PH but is very expensive so that probably isn't something you want to use.

Had something similar in mind as emails to the company haven't been too helpful. I guess its time to see how long one will last for science.

As mentioned in the title, I was wondering if anyone knows how well air pumps(the aquatop for example) work in high humidity environments, up to high 80s and low 90s. I've got a greenhouse near one of my outdoor miniponds that has high humidity at night and drops to the mid 50s during the day. and temperatures ranging from 10 to 20(and possibly more) Fahrenheit above outside temps according to the time of day.

From what was mentioned, the cooling system for the light is using the aquarium water so there wont be too many issues with chemicals going into the water if something breaks, the only issue would be occasionally going in and cleaning the tubes of any buildup to prevent clogging.

I recently came across a few videos from a YouTube channel by the name of Tech Ingredients and there were three that caught my attention. The three were videos where about DIY fridges, freezers and aquarium lights. Though in all three videos one thing caught my attention, the use of liquid cooling to divert heat from the appliances to warm another location, and in the case of the aquarium light video, heating the aquarium itself. I was wondering if anyone had any experience with similar attempts at heating your aquariums to cut the costs of heaters and issues with heater failure, or even the possibility of using said liquid heaters to somewhat heat outdoor mini ponds.
