hi guys, so i havent used my ro filter in around 2 months, im just wondering if i should change the membrane etc or if its still good to be used. thanks

Hi Everyone, Some of you will know that I have taken an active interest in Cyanobacteria (aka BGA). The reason for this is simple - I have had several infestations of this unwelcome guest in my tanks over the years. So, I tend to avidly read any new research that I find on what I refer to as...

Hi Folks, In one of my tanks, I need to lower the water pH to around 6.5, i.e. slightly acidic. The current pH of this tank is 7.54 and alkalinity/carbonate hardness is 3.0 dKH. I'm wondering about using peat, something I've never done before. Can anyone suggest a suitable product? I would need...

Hi all, I will be setting up an ADA 60p over the next month or so. I am coming from a marine background and therefore have a spare RO unit knocking around. I can't decide what route to go down i.e. 100% remineralised RO water, RO water cut with tap water or just straight tap water. I've...

Hello, I would like to have the chemical explanation of why water taken out of a tank, in say a cup, will have its PH rise and be > to the PH of the water in the tank. This is assuming the following: The tank has some aquasoil that buffers PH. Co2 is not being injected at the moment water is...

Hi, I recently built a paludarium with water flowing down the back wall, pretty much the complete wall. Im looking for advice on plants that I can use. The back is all lava rock, so I need something that doesn't need to be fully submerged in water, is OK with flowing water over its roots...

Hi Folks, I very recently got myself a copy of Diana Walstad's book, Ecology of the Planted Aquarium. In this book, Diana Walstad discusses plants that are suitable for soft vs hard water. Plant requirements on plant labels may specify lighting, temperature and CO2 requirements. But, they don't...

Hey guys. About to create my first nature scape tank in a couple of weeks. Gathering my supplies. So I was wondering what everyone is doing to change the water? I see this python changer getting a lot of positivity in the USA. But what about the UK? My concern about the python is how much...

Hi Folks, Recently, I have been making good use of the UKAPS thread entitled Sodium And Plants. I would like to extend this beyond sodium and beyond plants. Hence this new thread. I have found it difficult obtaining information about freshwater aquarium electrolytes pertaining to all aquarium...

Good evening all, I've kept Tiger Shrimp a few years back in regular tap water and they lived for a year or so but didn't breed, and I want to do it right this time. My current setup has been running for a month and a half. It's a planted 40x40x30 filled up to about 12cm (18-20 litres) with...

Hi Folks, Haven't been on here for a very long time. I have a 125 litre tropical planted tank with custom LED lighting and CO2 injection. I currently use Seachem Flourish (+ Flourish N + Flourish P, as required) but I sometimes wonder if I should also be using root feeding in the substrate. In...

Hello! So, I've got the new tank planted and set up, just in the process of waiting for it to cycle (with seeded media.) I went for a tropica substrate capped with a 2-4mm rounded gravel on top, was going to go full biotope but did so much research that I eventually talked myself out of doing...

Morning all, my first post on this forum as I'm struggling to get a clear answer whilst doing my 'google' research! I've been running a couple of planted, 'low/ medium' tanks so far, a 46l and a 125l tropical. They have both seen good planting results with a seachem fluorite base on one and a...

Hallo! What do you think, what param of water in aquascpapes is optimal? Given that I will to use all products of ADA (MH - lightning, additivies, fertiliziers) I have RO\DI Spectrapure and I can to make anything parameters of water. I want to know dKh, dGh, pH (in the middle of the day, before...

Hi Folks, I would like to better understand the mechanisms by which aquatic plants take in nutrients. Firstly, are aquatic plants equally able to absorb nutrients through their roots and leaves? Which of these do they prefer? Some plants, e.g. Anubias, are normally grown on driftwood or rocks...

Hi all, I live down in Southampton and have stupidly hard water! I want to try and breed and raise discus and am struggling to get my parameters correct. I have a bare bottom 100l tank which I've setup with an air filter and air stone. I have put in some moss balls from another tank and there...

Hi Folks, In my tropical planted tank (including fish), I use RO water to which I add Tropic Marin Re-Mineral Tropic salts. I also add sodium bicarbonate to bring the KH and GH to 5°dH and 7°dH, respectively. In as little as 9 days, the KH has increased to 6.5°dH. When KH = 6.5°dH, pH varies...

Not that I like researching the hell of each item I buy for my tanks, but rather I want to make sure I am getting the right thing for the job and not buying cheap and end up buying twice. So with my new shrimp tank project just kicked off, a kind member suggested I get a TDS meter off ebay...
