    Is my pH too high? Help please

    Hello :) I have a planted 24l tank with four male fancy guppies. The pH in the tank is 8.2, I have read that guppies like it between 6.8 and 7.6. I have a bottle of API pH adjuster, it says 1ml for 38l but it doesn't say how much that actually lowers the water by. I know that sudden changes in...

    pH out of wack

    Hello, I’m very new to the hobby and it was an emergency rehoming situation to which I obtained the fish. Long story short, I have the fish in a 54 litre but I am currently cycling a 105 litre for them. The 54 litre with the fish is currently cycling too The problem is my pH levels are not...

    KH and GH - chemistry advice please 👩‍🔬

    SO there have been a couple threads on here that I’ve found really interesting about water chemistry (I thinks that’s how you would refer to it) such as KH, GH, ph and water sources. I feel I was originally misled by my LPS (classic) as he said “all my fish are in the same water as you have so...

    Ph from tap reads 7.5 but in tank reads 8.2

    Just like the title says; my ph with the API master kit gives me a 7.5 ph reading (using the high range ph) and when I measure my tank I get 8.2. The tank is 5 gallons, has a sponge filter, houses one batta and has fluval stratum capped with sand. I read that aeration causes ph readings to go...

The ammonia was high, come to find out it was rocks that we separated and separately test and each had ammonia. I did a water change last night the ph...

    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...

    Rosy Cloud Rocks...Thoughts?

    Hey all! I'm setting up a 10g nano tank right now and found these beauuuutiful looking rocks called "Rosy Cloud Rocks" from Petco, brought them home, rinsed them well in hot water and just plopped them in my tank. I'm really new to this hobby so I didn't even know that rocks can change pH and...

    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...

    Cuttlebone for nerite and ph

    Hello everyone. I have a 20 gal tall with 6 Bleeding Heart Tetras, 6 Emerald Corys, and 2 Nerite snails. I have soft water and my ph generally stays at about 7.0. I have lots of plants as well. I am wondering if it would be safe to add a cuttlebone for the snails or if I even have to? My gh is...

    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...
