tried my hand at a couple of DIYs, but this took me 3 weeks to make. someone couldve made it it in a couple of hours. despite the flaws, it was the look i wanted for my tank.
it would be hard to pick one piece of equip let's face it they all kinda go together but in the spirit of diy mine would be my kalk top off that I made from a 1 gal sterilite container some airline tubing & a dripper that is used for drip irrigation works great was super cheap thought this give away was kinda silly till I looked at melevs set up & it was like a lightbulb went off.... duh... what a great idea & really looks soooo good
My most relied on piece of equipment has to be my controller. I use it for everything from photo period to heat control to dosing time to ATO. That one piece of equipment keeps my tank running and stable and without it I would not have the success that I have had in this hobby.
