    How do I influence, change and stabilize RO water

    So I made the decision to change to RO water because it can be used to create the perfect water levels for any fish you'd like. The problem is, it seems that to do so you have to know quite a bit about water chemistry. Hoping that the experts at TFF can help me out by telling me what kind of...

    CO2 and PH levels

    Hi all, I’m very new to the hobby and have just taken some test strips to check my levels. The Tetra app is telling me in need to buy a CO2 booster as my PH levels are too high and my CO2 levels are too low. I’ve attached the figures that the strips have given me. I also tested my Ammonia...

    Ph dropping significantly

    Hey all, We're beginning to run into a new problem. Over the past several weeks our ph has been slowly dropping, to where now it's about 6.8. A few weeks ago it was holding steady at about 7.6-7.8. I know that our fish prefer the lower ph so it isn't an issue at the moment, but we don't know...

    Conversion factor for Hardness and Alkalinity (K)

    Looking at our city's most recent water report they list the following: Avg pH 9.4, Range 8.5-9.9 Avg Total Hardness (as CaCO3) 189, Range 110-282 ppm Avg Total Alkalinity (as CaCO3) - 96, Range 47-138 ppm The scale the website where I buy fish from lists the KH (which I believe is the...

    Molly not quite right...?

    Hi all, I could do with some help with one of my platinum lyre tail mollies. We noticed today that he is sort of floating on the surface. I say sort of because he does swim around, albeit slowly. He has his mouth partially open, but doesn't open and close it. He also isn't eating. It almost...

    PH and driftwood

    Evening! Complete newby here. Joined a forum because of the false advice I keep getting given by aquarium shops (After failing my first tank from being told I can put a load of fish in a new tank after a few days). I'm now running a fully cycled 120litre stocked tank with no issues after a lot...

    What is so important about water hardness?

    Before I started my first aquarium I did about 2 months of research - mainly reading books. My needs were simple I wanted a peaceful community tank. But it's not all about the fish. Anyway - all the books and online articles had extensive information on how to cycle your tank so I was quite...

    DIY cement 3D background curing advice

    I have just recently attempted a DIY 3D background made from polystyrene and coated in cement, basically the same idea as you see here from the King of DIY. The construction went well and I am in the curing process but I am on week 6 and the pH is still rising. I let the cement cure for a few...

    Well water. R/O is still 7.6.

    Hi! So I've been trying to lower my ph in my tank from a staggering 8.4. I was wondering if i should use distilled water because I've been doing water changes with my R/O and some "api PH DOWN". It doesn't seem to be working that well I've done about 4 water changes with that method. Perhaps my...

    Using De-ionized Water to Lower pH

    Hello, I've been looking into keeping Apistogrammas however my local tap water has a high pH and is relatively hard. I understand Apistos prefer softer, acidic water so thought that I could achieve this by mixing my tap water and de-ionized water in a set ratio to reach a desired pH. I take A...

    Should I Replace the Aragonite in my 4 year old tank?

    Hi I've recently had an emergency in a relatively new 60 gallon tank of Africans. I have a 46 gallon acrylic tank that I set up about 4 years ago. It has about 40 lbs of fine aragonite sand. During the crisis in the 60 gal tank, I discovered my pH kit and the addition pH raising buffer were...

    If I were to use water direct from well.....

    I'm going to try and give the short version of my long story: I cycled a little 6 gallon Fluval Edge just over two years ago. I *thought* my water was hard because I'd tested the tap which was coming up 7.5ph. I stocked with 5 little male endlers. Tons of live plants. Over time I kept losing...
