zsxking Posted August 24, 2016 Share Posted August 24, 2016 Just start with Jebao DP4. It's a complete dosing system for the price of a single dosing pump. If it doesn't work out for you, you will know why and what to look for for your next one. If it works out, then there you go. It's also pretty easy to test it's accuracy if you don't believe it.

tetraodon Posted August 24, 2016 Share Posted August 24, 2016 i use the DP4 its great, only flaw ive found is one pump has a back flow issue, so whatever you do, put a one way check valve on it. Link to comment
cruiZe Posted August 24, 2016 Share Posted August 24, 2016 BRS pumps - not cheap but they're amazing and built like a tank. Got discount in group buy ? Link to comment

I was think getting on of those Jebaos but kinda iffy about the dosing accuracy,but the price is tempting BRS pumps - not cheap but they're amazing and built like a tank. Got discount in group buy Maybe I'll get two of these,but I don't have a controller do you think i'll be as effective I just use a timer? Link to comment
cruiZe Posted August 25, 2016 Share Posted August 25, 2016 Guess it depends how accurate the timer is. The BRS pumps flow stops dead when it shuts off. I was running mine 30 seconds 5x a day - then changed to 25 seconds ... Are there timers that have a seconds adjustment? If you dose for 3 minutes or 4 minuets that's just a big difference Link to comment

cruiZe Posted August 25, 2016 Share Posted August 25, 2016 Okay yeah that's true,which timers are you using APEX Jr so I can adjust it any way. I have Calcium dosing 6x 25 seconds and Alk 5x 25 seconds per day. Yesterday I was at 465 Ca / 8.6 Alk after not testing for 2 weeks and making the change from 30 seconds each so I'm happy with that.

holy carp Posted August 25, 2016 Share Posted August 25, 2016 You can get simple digital outlet timers that can do seconds, and some are cheap. That said, I use an Apex to time my brs dosers. I kind of used the BRS dosers as the excuse to justify investing in the Apex. Link to comment
JavaJacketOC Posted August 25, 2016 Share Posted August 25, 2016 Just get the Jebao from an Amazon backed vendor. It's cost effective and it's pretty simple to use. If you have issues with it Amazon is really good about making sure the vendor handles it for you. Link to comment

cruiZe Posted August 26, 2016 Share Posted August 26, 2016 Yes. Apex control is on a website. Works great on my iPhone , Mac and even crappy work PC Link to comment
cruiZe Posted August 26, 2016 Share Posted August 26, 2016 Look how much fun you can have tracking test results! Lol Link to comment

It can dose a lot, not sure about the per min but you calibrate it by dosing 100ml and I want to say that took about 30 seconds Link to comment
Spencer8857 Posted August 27, 2016 Share Posted August 27, 2016 I just pulled the trigger on the Jebao. The cost for servo driven glorified plastic tube pinchers is insane. $250+ for 2 heads and a simple LED and micro controller with some very basic programming? No thanks, even if it is made in the US. I'll stick with the $62 DC pump from China. Place the unit below your tank and you'll have no issue with back siphoning. I have a 20g tank so the dosing amounts can be small but I'm only doing eight.four every other day with calcium and magnesium every 3rd day. I will say that one of my pump heads has binding issues. I only needed 3 of the 4 anyways. Yes, I could return for a new one but I have a spare head and could probably make that one work if I needed to so I didn't bother. Hope this helps. Link to comment
