So in an attempt to be sure my TDS' are as low as possible I have noted the following. *Water produced by my RO/DI unit reads at 000 PPM *This same water sat in my mixing bucket for 2 days and remained at 000 PPM *I placed my heater and power-head in the mixing bucket and the TDS immediately...

I just started getting concerned about TDS readings, trying to get a feel for if I need an RO/DI unit or not. Here's my question.....What should the water in the tank be reading on the TDS meter? Ours seem awful high! Our tap water comes out to about 150-160ppm.

So about a month ago I had a major diatom bloom when at the same time I added new bulbs and a phosphate reactor. Not sure what sparked it. Anyway, after wiping the silly glass clean everyday for a month I was getting so sick of it. I let the diatoms build up for a week first. While cleaning...

Alright let me first say that our water sucks. 400 TDS!! I have been using my RO/DI for about 2 - 3 months and I have tested the water coming out of it many times in the past week and I keep getting different readings. Previously it was at 7-9, which I can live with considering where its coming...

Hi all...I have a RO/DI system that I got through ebay (very similar to this one): http://cgi.ebay.com/AQUASAFE-MAXIMUS-COMBO-REVERSE-OSMOSIS-WATER-FILTER_W0QQitemZ160243447351QQihZ006QQcategoryZ20684QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Question is...I have had it for about 2 years and I...

Originally, my plans were to buy the lights and filtration system off of the 120 setup to put on my 90G tank. I ended up buying the entire setup. This is a picture of the Dining Room they are sitting in. The 120 is on the right, the 90 is on the black stand. When I first got it, I intended...

Can a test kit go out of date? No matter how many and what percentage water changes I do my test kit reads 80ppm on the nitrates in my tank. I just did a 20 percent on friday and sat morn I still read the same. what is causing this? any help would be greatly appreciated!

So it seems I've contracted some type of parasite in my tank. I have lost a couple of chromis, but all the other fish seem to being doing pretty well. Whatever it is I don't see much on the fish (I think maybe oodinium) but some of the fish are still scratching. I've been doing all the "in-tank"...

Hello all ,I have a question about my water system .It is a six stage system with 3 di canisters and is only like 2 months old and everything has been fine till my last bunch of water I made my tds was up like 25 I wouldnt think the filters need changing yet. What the question is how long and...

I was wondering how many of You have replaced the RO membrane in your RO units in the past. Not the other Cartridges just the Ro membrane

Alright, so I got the tank today! Its about 190 gallons. Its going to take a while to finish, since we have a wedding in September, and will probably be moving back to Fresno to buy a house. So this isnt going to be quick, but hopefully will be worth while. The tank is 60" long, 36" deep...

Hell again, I have a quick question about tds meter should I get a inline meter or hand held unit? I know the inline is better but will the hand held one be good enough?

Hello Lady and Gents I am very new to the saltwater hobby I am crossing over from Freshwater. I just got a 110 gallon tank. I have a sump, and overflow. What should I do to get started and what else do I need in my tank???

Where is the best place to get water in town...or do you make your own? I have an ro/di unit but I would have to buy new filters and I'm trying to decide if it is worth the investment or not. It's nice to have my own filter, but the filters are expensive, and I have to pay for water in my...

Is a TDS reading of 75 acceptable without an ro unit. I have a unit and it registered 5-9 on the meter but... what if I didn't use it??

Does anyone know if HD, Lowes or any other stores sell the wrenches used to remove the filters from RO/DI units? My wife accidentally threw my wrench away.

For just under a year, I've been stalking the forums to learn as much as possible before building my first reef tank. What began as a 72G bow has been revised to a 30g nano after learning of a job change that will move me across the country. I just finished the tank and stand two weeks ago, so I...

I use the same brute cans to store my ro/di water as I do for mixing saltwater. Once I"m done mixing I rinse with freshwater then go back to storing fresh water in it for TO water. Could the fact that the can has had salt in it skew my TDS readings by a lot? Coming out of the ro/di I'm reading...

Well, I have had my RO/DI unit for about 4 years, and no matter how I dial it in, or replace the cartidges, I can't get a TDS reading below 34 anymore. So it was suggested the the membrane is starting to go bad. If it is the membrane going bad, it was also suggested that in some cases, it is...

I'm having a bit of an algea problem. Also seems to be just this layer of junk on my live rock... I know I need more snails, so i have about 20 turbo snails for my 65g. How many should I get? Also what are the best snails that'll really do a good cleaning job? I was thinking maybe a Queen Conch...
