You don't put water inside the diffuser!
That diffuser was probably on a timer and had been switched off..... and water has seeped into the chamber!
Best if you soak the new diffuser in water for a few hours this will help to let the Co2 out!
75....Will be far better for a 60 litre!!!
75 is pretty powerful.....I have one installed on a 35 Litre Denerelle Scapers Tank.!
I increase the flow to the max...every now and again, just to remove some crud on leaves and detritus....but it is like an old fashion upright washing machine...
Used one in this journal....you can always keep it as a backup if you run out of Fire extinguisher/cylinder Co2!
You mean the Bubble Counter!
Drop Checker goes in the aquarium to monitor Co2 levels;)
Those plastic check valves are not much good...they tend to fail.
Try moving the Check Valve just above the Bubble counter for the time being.
Purchase a couple of better quality valves like below.
Could be due to impurities as Filip stated....I'm sure the KNO3 I purchased way back did have a slight smell of cheese!
Containers are easily mixed up....especially if not marked up on both the lid and the bottom half of the vessel.
Your KNO3 could be another fertilizer...very similar in colour texture.....KNO3 has a blue cheesy smell to it I've read in the below article by Clive...
This bacteria is similar to the white film that grows on wood added to an aquarium.
Usually a combination of a New Set - Up Aquarium/Immature and unhappy plants!
Clean off the scum/film and do extra water changes a tad more surface agitation will help and it should disappear eventually.
Welcome to the UKaps👍
I like the option of these filters as the flow can be reduced very considerably.....from full power to a gentle cascade!
Yes I did add a Dennerele Nano heater but the temperature adjuster got stuck at 22 degrees..... so I replaced it with a
No issues with this heater 👍...
Yes, Ive used Tropica soil/powder it always lowers my hard tap and reduces the pH.
Eventually it loses its ability to lower KH/pH after a number of years!
Tropica Aquarium Soil is a Japanese natural volcanic granulate material. Aquarium Soil naturally reduces your KH and pH value and enhances...
You need to add Nitrate, Potassium, and Phosphate and in some cases Magnesium...also!
Plecos will rasp on plants and cause leaf damage!
The floating Amazon Frogbit looks pretty green so maybe lacking Potassium/Phosphate/Magnesium.
A few more details would help!
Could be Crypt Melt....or a Co2 distribution issue!
How long have the Crypts been planted?
Best if you remove all affected leaves as they will just add waste matter to the water...
Light coloured new leaves are normal in most plants, the leaves will darken with age!
5ppm is a tad Low in my opinion this may lead to distorted leaves.
Tropica Premium is a Micro/Trace fertilizer your missing out on NPK for the plants!
Probably better to switch to...
Hard water isn't a problem....Co2 is more of a issue if you want to grow some plants!
You can grow plants without Co2....like Microsorum/Anubias/Crypts/Vallisneria/Amazon Swords/Bucephalandra although these will grow slower.
Just like to say a few words regarding one of our sponsors Horizon Aquatics.
Placed an order on Sunday and received it today so a big thumbs up👍 on Delivery!
The rock looks great.
Packaging excellent, and the revised order was all shipped together :happy:
Thanks for that Nicole 👏
Don't worry too much about Nitrate as I say Co2 is far more important.
Never found having high nitrate causes plant issues......I have similar Nitrate ppm tapwater and very, very, hard water!
Lower Nitrate can cause growth issues with some plants.
I would increase lighting to encourage the...
Your tap water parameters won't cause any issues!
Stable Co2 is far more important.
You are aiming for a green drop checker colour before lights come on......6 hours light duration at the start.
Not sure of the fertilizer you listed can't find any information on that product!
Just dose an...
Your are actually using a Co2 in a Liquid form!
Use it as it describes on the bottle as per litres....up your fertilizer to full EI.
Direct flow down towards the base of the Java fern or move it nearer to where there is suffice flow around the fern......I would hard prune affected leaves....they...
Attach a small long bristled paint brush onto the tube with elastic bands/zip tie....use this to waft above the substrate and in amongst the plant stems!
This is the best method Ive found when removing gunk thats laying on top of Tropica Soil/Powder substrates.
You can't overdose with Mg......just add 1/4 Teaspoon once a week!
I would cut the top off the repens and replant the new growth.....bin the old remaining bottom half or use it in an emersed cointainer;)
Leaf degradation is usually due to low or poor Co2 distribution!
You are looking for a least 10x the volume of the aquarium 600 litres per hour to help move the Co2 to all areas.
You could consider upgrading the filter as the Dennerele is pretty feeble at only 150 Litres per hour.
