Re: New keeper : Q : When do I use all these products in the tank? #51
The water conditioner removes chlorine/chloramine and neutralises heavy metals. It should be used on the first fill, at every water change and whenever you top up. The biological enhancer adds beneficial bacteria. You can add a dose to help your fishless cycle to establish, at the same time as you add your first dose of ammonia (see fishless cycling article here: https://www.fishkeeping.co.uk/articles ... hless-cycling-article.htm ). The biological cleaner is a pointless chemical and I would not use it. The final bottle seems to be plant food - use it as directed if you have plants.

New keeper : Q : When do I use all these products in the tank? #52
I have a new Fluval Roma 240 tank and I plan on having a community tank. I am trying to read up and watch as many videos as I can before putting any water in the tank and learning about hardscaping.

I have most items and I believe this is correct?

(no fish in tank yet)

Put water in and add...... er.... I have these Fluval products but not sure when, how much or how often I should be putting them in. Can anybody advise me? I thought it was fill tank add a product (ot sure which one) leave for a week then change 50% water and repeat weekly for a month.

Not sure what to add as stated, how much or when, and how often to use Master test kit.

Any help appreciated.

Re: Plant & algae woes #53
I wish I could help but unfortunately, although some thoughts strike me, I don't have sufficient plant knowledge/experience to be able to help you comprehensively and so I hope a plant-keeper may be able to offer their views.

Re: Too much ammonia #54
You can add it, but don't do a water change as you need the ammonia for the bacteria to feed on.

Re: Too much ammonia #55
Done another test tonight. Ammonia reading at 3 but nitrite has increased to 8.

I’ve had a my delivery of Dr Tim’s once and only which says reduces ammonia & nitrite naturally whilst adding the good bacteria.

Worth just adding this or do you think best to do a partial water change then add it??

Plant & algae woes #56
Hi all, long time lurker, first post!

I've had a 40L tank for 5+ years now (small flat so can't go bigger).
I've always struggled to keep plants. A few months ago I did a complete overhaul - new Tetra complete substrate, gravel, new Interpet PF2 filter, new decorations, Echinodorus plants & moss balls.

Unfortunately the plants are dying off and I am getting cyanobacteria & brown algae on the gravel.
API test kit results are all fine.

I dose API leaf zone (5ml) weekly & API CO2 boost daily (1ml).

Light wise, I have a LED tube suction mounted internally on lid (can't use any side mounts).
Experimented with just a few hours of light to all-day, seems to make no difference. No direct sunlight.

Not sure what else to do really, its super frustrating.
Currently only have a couple of tetras in there, looking to get a few more and couple of corydoras in due course.

Any advice welcomed!

Re: Too much ammonia #57
Either will work - personally I let it drop to close to 0 before topping up.

Too much ammonia #58
Been following the instructions of the cycling article

3) The following day use the ammonia test kit to measure the ammonia in the tank.If it’s below 3ppm (parts per million) use the ammonia calculator below to calculate how much ammonia to add to bring the level back to 3ppm. It may take several days before you see a significant drop.
4) Repeat step 3 every day. This process is to start the cycle off (the initial bacterial growth) and keep the bacteria alive by feeding them ammonia at the correct concentrations in the tank water.
5) After about a week you can start to test for nitrite in the water. Ammonia is converted to Nitrite in the first part of the cycle so when you can detect it, it means the cycle has started.
6) Continue testing for ammonia every day. Whenever it drops below 3ppm add enough ammonia to bring the level back up to 3ppm using the calculator to obtain the correct dose. Also test for nitrite every other day. You should see nitrite rise and then start falling after a few weeks

got a healthy ammonia reading of between 3/4ppm and yesterday nitrite was at a reading of 4.

Reading other posts there is conflicting information as to whether to follow the above instructions and every time the ammonia drops below the 3ppm to top it up whereas other posts have said don't top up until the ammonia goes down to 0.

feeling rather confused.

Re: I don't know what I need to do next with my fishless cycling! #59
It seems to be progressing as expected. The nitrite rising is what you see when ammonia goes down. You won't see nitrate rise until nitrite starts to go down which is usually a week or so after ammonia has started dropping regularly. Until then nitrite will continue to rise, way beyond the level the test kit can read. Your first indication that it's dropping will be a rise in nitrate.

Re: I don't know what I need to do next with my fishless cycling! #60
So we have SOME progress (I think!)

I turned the temp up yesterday to 28 degrees (i didn't do a water change because i wanted to wait and see what happened) I have tested the water today and have the following:

Ammonia - gone down to 0ppm! yay!!

Nitrites seem to be between 2-5ppm which seems like a good sign to me.

but.... nitrates are coming up as 0ppm..... that seems odd to me? with the ammonia going down i would have expected to see some nitrates?

sooo.... does it seem like i'm going in the right direction at least?

now ammonia is at 0 i'm going to dose it to 2ppm this evening and will test it all again tomorrow.
