Best investment purchase you have made in the hobby.

Rollermat. I went with AquaMaxx. So happy not to have to deal with filter socks again!

Not sure what the best is. I can make a much better list of things I’ve wasted a ton of money on though

ATO / Auto water change system & RODI & Mixing station.

I need to end up buying one of those!

Some of the best purchases are absolute requirements, like an ATO or RODI system. I can't imagine even trying this without those.

However, the first thing I thought of when I saw the thread was the Neptune Apex/Trident systems. I don't control a whole like with them yet but I monitor the heck out of my system and manually dose the alk based on the results.

Number 1 is my ATS. Although it's a DIY it was not a cheap investment. I took me to a new level.

Number 2 without a doubt is a filter roller.

Life insurance, for when I do something stupid in a tank or the wife has had enough of my hobby shenanigans!

Seriously though, RODI unit hands down.

In the 90s I grew lots of acans And sticks. bought a bunch of cole Parmer pumps for ato and kalk reactor, calcium reactor, water changes etc. years later when they came out with reliable aquarium grade devices I sold some of these pumps off and probably pocketed at least $15000 bucks After reselling them did the same with some toledo mettler gear. It I consider almost every hobby brand purchase to be a straight up loss but by buying lab grade equipment it lasts longer and retains its resell ability.
