hardness

Hey everyone, I've got a query that I'm struggling to solve about water chemistry. There are no fish in this tank, so it's not an urgent fix just looking to understand. It's a 180L (roughly 47 Gallon), 120cm/4ft long tank. Has been setup for 6 months as a daphnia/micro invert/plant tank but was...

Hi all, I recently had a good discussion on here about the minimum number that should be kept of particular species and during that discussion discovered that my tank may have some fish that may well be unsuited to the tanks water conditions , hence this new post to try and establish which...

So on the back of another thread I thought it would be worth sharing these reports on a separate thread as I believe that they show that the water hardness readings in this area increased significantly from 2020 to 2021. The 2020 water was on average 6.01 dH and within a range of 3.74 to 8.28...

Hey guys, I have been doing research on whether water softener systems in houses is safe for fish keeping. My original water in my area is well water with GH and Kh up in the areas of 15-18 (dgh and dkh) and the ph at 8.2. My family installed a water softener system (works with water crystals, i...

Hello! I have a 20 gallon with a male Betta, 6 rummy-nose Tetras, and a Nerite snail. I check my water regularly, and everything is fine, save for the hardness. My GH is weirdly low at 1.5 dGH, while my KH is very high at 15 dKH. I use API Proper pH 7.0 as a pH buffer, which claims to cause...

I'm keeping livebearers: platy, molly, guppies. The platy and guppy do ok, but the molly's always have issues. I lose fish every now and again to common livebearer diseases. My tank parameters have always been good. I use an Api kit. Ammonia: 0, Nitrite: 0, Nitrate: 5-10, Ph 7.8, temp 78. Water...

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...

I've decided to rehome my endlers, as I can get the PH where they like it but never the hardness. Shrimp seem to do well in my water...when the endlers aren't terrorizing them...which they have been lately... So, this weekend I'm driving them to a new home and will concentrate on my shrimp and...

Hi! I recently bought 2 juvenile golden dojo loaches. I'd identified them as tank-compatible in the past, but hadn't done much recent research and had to decide about the purchase on the spot. Now, for 2 things in particular, the internet seems to contain contradictory and even opposite...

Hey guys;   Thinking about getting a pair of German Blue Ram Cichlids. From what I've read, they require water that is on the softer side, with low pH (5-7). My municipal tap water is moderate on the hardness scale, but the pH is relatively high (~7.5).    Do you have any suggestions on how to...

Hello All - I'm new here. We have just bought a couple of nano tanks and we are both lucky enough to work in laboratories. This gives us unfettered access to grade II laboratory RO/DI water and water test kits, which is good given our local water isn't ideal for tropical tanks. We'd like to do...

I am setting up a black water biotope 50 gal aquarium, and a similar 35 litre quarantine or hospital tank. I ran the 35 litre tank with sand, bogwood, and almond leaves and the ph stabilised at 6.5, with GH at 3o DH. I then added Nutrafin Aqua+ to remove any chloramines, chlorine or heavy...
