Whats You'r Single Best Investment

[don_chuwish]

Best: Apex Lite - it has been very extendable with a low entry price, growing with me in the hobby
Worst: Used 120G with no center brace - fixing it proved folly

Continuous automated water changes

By far the @Hanna Instruments checkers. Alk, phosphate, ph/temp handheld and now copper. Next would be the apex to control it all.

Note. I’m color blind so doing test color comparisons requires me to get help from my lovely bride. The Hanna makes it easier for me to do tests when she’s not here

for me it was my glass aquarium, before that i had nothing to hold my water and expensive rocks.

Best thing I ever bought for my tank was a CaRx in 1998. Still got it. Not an investment though LOL.

I couldn't live without my Apex controlling my remote ATO and automatic water changes feeding water from the mixing station & RO/DI tank in my garage to my tank in the living room. I haven't had to carry a bucket or drag a hose into the house since the first day I filled my tank.

Patterson certified calibrated thermometer.
Every temperature related piece of equipment including my heaters, inkbird and seneye have always read differently. Finally I know the true temperature.

good tip, thanks

I have no idea what any of this stuff is, or why you would need any of it. Maybe it's me.

Excedrin. The big bottle.

My Kessil H380. I been fighting with nitrates and phosphates . Within a week the cheato was growing so fast the nitrate and phosphate cane right down and in line

Single item would have to be my Apex. I would not set up another aquarium without one.
