ppm tds

:help: My normal water change is 15-20 gal twice a week. My procedure is fill my 44 gal brut with RODI on one day Next day heat up water. Next add salt. All the time mixing with pumps. Then I'm set for the week, 15-20 gal change on Wednesday and 15-20 on Sunday. Sometimes I switch it up...

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...

I just bought a HM Digital TDS Meter from Russ @ Buckeye Field Supply... so I know I have a great quality device. My tapwater after its been thru my wholehouse filter plus the watersoftener reads about 175ppm leading into my RODI. The RODI water coming straight-off my unit is reading 0.5ppm...

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??

Asking for a friend, I'm still looking at crossing over to the salty side He has a 30g SW that will end up a reef tank. Its been set-up for about 6 weeks and has a few fish in it (one's a tang, which I need to talk him into getting rid of). Any way, He had a few pieces of base rock and a few...

I am looking into gettin an RO/DI unit and have been doing some research. my only concern is the amount of waster water and i have read something on this forum about pumps that push the waste water back through the filter again and decrease waste by 80%. wondering how many people have had...

Hey all, I have a Kent Marine Maxxima 35GPD unit with dual TDS meter. I have my meter set up to read the water going into the DI cartridge, and the water coming out of the DI cartridge. I just got all new filters (DI cartridge, Carbon block, and Sediment filter). My reading after the DI...

Ok my reading going in is about 240 and now coming out is 33. It used to come out at 5 or below. Does this sound right for that high coming in? Are does this mean something needs to be replaced?

Well, I've had a "BB" tank for 2 years now, but it's only in the past month that I actually had a real BB tank. That is because (i feel) I had too much rock, poor flow patterns, and def. not enough fish, or skimming. Here was my tank at it's...

Question 1: My tap water is horrible here I have been going to the grocery store and buying 5 gallons at a time of "purified" water from the fill it yourself dispenser. At $.20/gallon I would rather go to the store once a week and buy water rather than pay 150-200 for a RO-DI system. Does anyone...

Ive freshwater dipped a few sps before with no real negative effects.......but check this out. I treated my tank with Interdeptor last week and tried to save a few acrocrabs......so i FW dipped a couple corals in an effort to get them to jump so i could save them. Well it worked......BUT...

this will be the new site for the reefzilla thread. once i get new pictures from bill i will post all the pictures in a row all at once. that way there is a huge batch if picture in a row for every one to see. bill will be able to post here on this site. please dont post here until we get all...

Alright, last time I was running a RODI system here the pressure seemed really low, I was thinking this time when I buy a new setup about getting a pump to go along with it. Any info I should know about this? or isn't it worth it? I'm not on city, I am on well water.

I have been having some problems with my newer (almost three months old) tank with hair algae so I picked up a TDS meter to check my RO unit. I have a 5 stage RO/DI unit that I picked up off of ebay. The TDS mete reads that my tap water is at 30 however my RO water reads 15-18 depending on how...

I know jack about these.....so which to get?:help: :help: I would say anything around 60 GPD.......would be plenty. I also plan to use it as drinking water, not just for filling the tank! So which to get?:eek: There are so many and I want to be sure I get a "reputable" one and all I need...

Ok so here is my deal. I had less trouble with phosphates before I bought a R/O unit (8weeks ago). I tested the water from my unit after I noticed the increase in algee in my tank. the readings where 344ppm with a friends TDS meter. My tap water is 294ppm. I checked the water before the DI...

just received a tds pen and some calibration fluid. on the packaging it says 800 ppm tds solution and then I guess its got a chart of different ppms at different temperatures. So do I dump this fluid somewhere and get the tds pen set to 800? heres the solution...

Hey guys! Hope everyone is well! We've had so much rain lately I was wondering.....has anyone used rainwater in their tank? I probably could have collected at least 5 gallons this last week.

My TDS PPM is 032 before Di and 003 after Di, Do I really need RO/DI unit or is my DI unit enough?? Does DI remove clorine or is it the RO or A. Carbon that does? Thanks :agree:

My local water supplyer carries purity water and R.O. water. The R.O water is ran through a 12 filtration system. And the Purity water is ran through the filtration system twice. the percentage is the cleaness of the water: Purity water 97-98.99% R.O. water 85-93% If I switch to...
