I've had a dp4 or whatever it is running for like 8 years! Ive only replaced the heads once. I have an apex DOS here that I'm going to install sometime but I have not felt the rush to do so yet.cheap jebao dosing pump that get's a "don't buy it, it will break" rating on most reefing forums
i purchased two, one to keep as a spare, haven't needed the spare yet.
been running 3 years now.
hope i didn't jinx myself with this post LOL

One of my other best buys was some cheap $12 powerheads off of ebay. I threw one in my mixing barrel and one in the sump to mix up things that get dosed and those things have been running for 5/6/7 years too. Sometimes cheap stuff breaks - sometimes it doesn't.
Sicce return pumps are also amazing. I had a couple running my main system for at least 5 years, probably more. I rarely cleaned them and they still started up every time. Definitely can't go wrong with them. I still have them as backups, just switched to fancy DCs like everyone else lol.
