My incoming TDS is about 250, RO membrane takes it down to 2-3, but a brs canister of DI media only lasts a month before im getting 2-3 TDS out of the DI again. Don't see anything funny on a ICP analysis, so how long should it last and what can I do better? System has 2 x 75 gpd membranes, auto...

Does anyone have a good source for a NIST tracable seawater standard? I've recently installed a neptune trident, and the reported values after calibration are very different from my hanna checkers. The hanna checkers have been tested against the hanna standards and are in range for the test...

Does anyone have an auto flush valve that operates off of a tds reading? I'd like to have my system auto flush intelligently. ie, flush until tds drops to a certain level. Thanks Sent from my SM-N950U using Tapatalk

How many gallons do most of you get from a single canister of di resin? I have a brs 6 stage RO system, 150 GPD water saver, with booster pump and 500 mL/min auto flush. Tank is 46 gallon, and evaporates 4 gal per day which is replaced by ato. 15 gal water change every two weeks. So, I go...

What is the groups opinion on one vs the other of these? BRS has a video claiming the phosphorus checker is better, but needs a conversion factor to phosphate. Neptune apex does the conversion automatically, so that's negligible. My phosphate checker broke (fell and cracked) and I have...

Wondering if anyone in the western burbs has a blue velvet nudibranch that needs to be fed. I've had a flatworm infestation that I can't kill off. I've been trying flatworm exit and it seems to work but they keep coming back. Maybe a naturAl predator will get rid of them? If someone has a...

Hi, I have a reef octopus 110 int skimmer that uses an aqua trace 100 pump. I snapped the impeller shaft when removing the impeller to clean. I can get a new pinwheel impeller for this pump, but I'd love to use the spare jebao dc3000 I have sitting around. Has anyone converted the dc 30.0 to...

What is the general consensus on age of a tank to add a clam? I'm running a 46 gallon zero edge with 2 ai vega color led about 12 inches above the tank. LED's are at 40% power. Tank has been running 4 months, but was heavily seeded from my old tank that was 6 years old. Nitrates 0 Nitrates 0...

I have two eheim Jager 10 heaters in my 46 gallon tank, 66 gallon with sump. Heaters are installed on two separate digital aquatics pc4 units, both on channel 1. One of my pc4's reads 1.6 amps when the heater is on, the other does not show an amperage reading, so that feature may be bad on...

Does anyone use these for a quick and dirty check? Granted a titration or colorimetric test is more accurate, but what are the groups thoughts on a simple dip stick test for following a tank cycle, or routine testing supplemented with a less frequent and more accurate test? Just wondering, thanks.

Well, my wife got me this for my birthday, so it's her fault if I disappear into the basement now, right? This is a used Zero Edge 46 gallon, three sided aquarium. It had most of the parts, but a few replacements needed. Got a Jaebo DC3000 to keep it flowing, still thinking about what to do...

I'm looking for some ideas on what I could coat the inside of my stand with to contain spills. I was going to try spray rubber, but that's a lot of solvent to evaporate off in my basement. There are also rubberized roofing paints, and adhesive roofing sheets. Has anyone used any of these, any...

I'd like to setup my RODI system to turn off automatically when my float switch trips. Has anyone used a solenoid based system go shut of the feed line to an RODI system? If so, would you be willing to share the system design and source of materials? Thanks, Kyle

This is my first thread and I hope to document the build of a new tank my wife bought me for my birthday. Arriving today is a 46 gallon zero edge aquarium with sump and cabinet. This is a used tank so still needs a few components. I'm looking for some recommendations on a good, quiet return...
