I have 2 Superfish Aqua Flow filters. One part has a sponge containing carbon. One part has sort of Hula Hoops in a net bag which collect the beneficial bacteria (this is called CrystalMax). Does anyone know 1. How to remove the carbon, if using meds, without losing physical filtration? 2. How...

That is such a brilliant idea from your wife! I would love to do something similar - even have a suitable window - but how are you managing the temperature difference between the outside wall of the tank and inside wall of it?

Well, that exhausts my knowledge and ideas! I hope someone else can solve it for you 🤞

I have always assumed that all contacts of the person with the app had to isolate too? The rules are mad, and Track and Trace are/were an expensive joke. And not paying those who are forced to be part of the awful gig economy for time off work to isolate is barmy. I agree with you NannaLou.

I've not seen any of these things in the UK. We must have different regulations or something.

Three!

Maybe they have no fish???

I just checked. High phosphates can cause algal blooms.

Could you have a problem with another parameter like phosphates?? I know silicates increase the risk of diatoms but have a feeling I read phosphates can influence things like algae too.

That's a really good point. I suppose the problem arises when we try to mix fish from different ecosystems.

That's brilliant. I gave up on dwarf gouramis because of their health issues but honey gouramis are beautiful too. I'll watch out for food issues. Thanks for the tip!

Would these fish mix well in a tank?

I think I have a long hose I could use for that. For refilling I bought a small fountain pump in the end. That way I can make sure I'm pumping warm water back into the tank from a bucket. I'm not sure how I could do that from a tap as my hot water supply contains heavy metals from the loft tank...

Costs a bomb in water bills, unless you can catch the wasted water for another use. We have meters over here and water is expensive.:(

I feel very envious of those members abroad who can live in huge houses, have huge garages and have huge tanks! The UK just lacks space :/

Am I right in thinking that if you replace water this way you should include some hot, boiled water to warm it up close to the tank temperature?

Perhaps you could try using long tweezers, e.g. aquascaping ones, to take food lower in the tank? Or distract the sword tails with food one end of the tank while feeding the others at the opposite end.

They add phosphorus.

Absolutely certain. I have tested and retested with a liquid kit.

My KH has risen to 7 and my pH is somewhere between 8 and 8.5. Perfect!

If you haven't had it before then chances are it is due to nitrates building up while you were away, hence water changes should help.

Thank you Essjay. I'll do that now!

My tank seems to be cycling (my ammonia has dropped from approx. 3 or 4 to 2 in 3 days, and my nitrites increased from between 0.3 and 0.8 to 1.6 in the same time) but my KH is only between 1 and 2 dH, as is my tap water. Will such a low KH stop the cycling or just slow it? Does it interfere...

A number seem to require more tank length than I have, but the Glowlight and Pretty tetras look promising.

I'll look them up!

I've tested my tap water and hunted for appropriate fish, but I'm having problems. My tap water parameters, as checked with the Tetra water test set, are: GH 3 KH 1 or 2 pH somewhere between 7.5 and 8.0 (my water supplier quotes 7.4 to 8.8) I have an 80l, 60cm long tank which is planted and...

I found some online here in UK. My lfs doesn't stock it, only the marine kit for £117! I'm glad I'm doing freshwater fishkeeping. Thanks Avel1896. I'll get some if Salifert doesn't do the trick since I have already ordered it.

Hello Avel1896. Thanks for the advice. I took a look at JBL and would consider it in future, but for now it is ammonia testing that I really need and the JBL kit doesn't cover it, sadly. Still, it's a fascinating way of testing.

I've gone for Salifert ammonia and nitrates. I'd love to try Hanna testers but have just received a £900 bill for car repairs so I'm skint for now! Thanks again for your advice.

Yes, the Salifert is repeatedly reported as underestimating the ammonia levels, which is rather worrying. I usually assume 5% of 1 star reviews is average but the Salifert has many more than that on the website I checked (I don't know which that was now). If I start collecting more tanks I'll...

Hello! I think there is a good amount of info. here on plants so it should be the right place.

Sadly, a lot of the reviews are quite poor.

Ouch! The Hanna is a bit expensive at £81 with only 10 tests. My diabetes gear is cheaper! But the Salifert looks good. Thank you for the suggestion. I'm off to buy some :)

It's a liquid kit.

I already have a Tetra master kit covering nitrite and pH. I've seen that NT labs do an ammonia test kit that might be promising.

Hi Tacocat. Yes, my kit is the single test from API. I suppose the master kit might be more sensitive for some reason. Is yours?

Hi all. I'm cycling my tank but have a problem in that my dipstick test will measure 3 ppm but they are known not to be very accurate, however my test drops measure either 2 or 4 ppm rather than 3. In order to achieve the 3 ppm test could anyone recommend a testing kit, preferably one available...

Regarding the stocking, have you looked on seriouslyfish.com to see recommendations for tank dimensions and size for different fish? I suspect your tank may be a little small for your ideas, although I don't know all the fish you are considering. The website will help. And your English seemed...

Hello. I'm not quite sure what you mean when discussing the 2 options for layout, but I thought I'd suggest that adding CO2 might help your Alternanthera, although it might make little difference without sufficient light. It could be worth a try. However, it will probably alter your pH and KH so...

I have some Eriocaulon cinereum that I love, but I have no idea if I can keep it alive. It's new, like me. It should at least flower before it dies!
