My litlle 250L garden.

Currently trying high dose of K (12grams K2SO4) whic gives me 25ppm in tank
How are you dosing this? 12g in one go? Over sometime?

Your plant mass is large now, and your flow will be affected, it could all be related to bad flow and CO2 and nutrients not getting to where they need to be, you still running the same filters?
 
Yes I dose 12g with 50% water change. But so far I haven't notice any benefits of doing this.
Still have 2 external filters aqua one 1200l/h
suply Co2 thru atomizer.
do u think I should split dosage of ferts?
 
What do you think LondonDragon?
I am planning to restart the tank on Sunday, in the mean time I reduce the light a little bit because I had over 0.86W/L
 
For a 250l tank you should start with the recommended dosage:

Macro:
2.90g KNO3 x 3 times a week
2.46g K2SO4 x 3 times a week
10g MgSO4 x 3 times a week

Micro:
1g Trace x 3 times a week

Dose Macro after 50% water change then alternate between Micro and Macro.

After a couple of week adjust if necessary, if you see deficiencies increase everything by 20%, monitor for two week and see again. That's how I do it and it never failed me.

Note as your plant mass grows you need to increase dosage as well and not keep it the same, CO2 needs to be tweaked also, and you have to watch out for changes in flow patterns due to plants growing in the way of flow, etc...
 
Hi

I notice you're not adding any phosphate, I reckon you need to be...could be a phosphate limited tank at the moment. Green spot algae also backs this up as is usually a tell tale sign of too low phosphate.

cheers

Do add PO4 and quite a lot, 1,2grams weekly, which gives me about 3ppm.

Any way tomorrow it is going to be very busy day as I am going to re-start my tank. This time I am planning to make some Aquascape so I will reduce mass of plants quite significantly creating some space for redmoor adn few dragon rocks.
 
fair play, good luck with the re work and figuring out your new tapwater... I look forward to seeing the changes as your last tank was great!
 
Hi Every one.
Restart is done.
This is the first time ever this tank is so low planted :-/
At the moment it looks like little desert :)
All I know aquascaping is not a easy think i seems like I am crap.

Come on guys no comments? Is it really that bad :(

I started using half of my lights 2 tubes only which gives me 0.43 w/l
a lot of co2 as always and testing new ferts from tropica.
at the moment spoted few holes in ludwigia leaves.
Lack of K I think.
 
whats the back center plant and also the very front plant? inbox me id be interested in a sample of you please Tom.
Many Thanks
Tom :)
 
Macro: 2.90g KNO3 x 3 times a week 2.46g K2SO4 x 3 times a week 10g MgSO4 x 3 times a week Micro: 1g Trace x 3 times a week


what are these chemicals and could you tell me where to buy them, view my tank, its 200l gimme some details please i want mine to grow good :)

can you tell me what they do, why i need them.
perks off having them.
thank you
Tom

that is P. Stellatus and on the front there are blyxa bushes and a bit of Hemianthus micranthemoide.

These are dry salts which we use in EI method.
You can get then from here: FluidsensorOnline.com, The Nutrient Solution

I ran my tank last few years using EI method but at the moment trying dosing TPN+
 
Hi guys,
Update after 3 weeks.
I have been using tropica Ferts premium, and I am not impress so far.
I haven't noticed any significant deficiencies on plants really. Only new leave of cryps seems to be a bit bright green and Eleocharis sp 'mini' doesn't at all..
Main problem are algaes, I noticed Green Dust Algae, some spot ones and Oedogonium.
I started with recommended dosage of 25ml for 250L tank, and last two weeks I increased dosage to 35ml.

Do you know guys what cause this?

Hi Thomas,
i think its looking pretty nice actually, with some promising new growth from the hairgrass and crypts and a vibrant and fresh feel with nice colour contrasts in planting, hardscape, substrate and fish choices :)
The old crypt leaves will most likely be emersed form so will not take on the submersed form and thus only the new leaves will look as they should. You could try trimming off some of the older leaves if you dont like the look of them, this will encourage more new growth. Some of your issues could be due to the fertilisers, not directly, but because you are using only the Tropica Premium type which does not contain the two main macro ingredients of N & P. High tech tanks will need these supplements to flourish so maybe consider the Tropica Specialised fertiliser to get the best from your set up. Tropica fertilisers are great in my opinion, but when cost is an issue, then EI is the way to go as you already know :)
The oedogonium algae may actually be the start of staghorn, and if your gda is limited to your rocks then a toothbrush and a bit of elbow grease will bring them back up......i suspect using a fertiliser containing all the macro and micro elements may well help rid you of these issues along with good tank maintenance :thumbup:
I notice you had started with only half your lighting abvailable of only 2 tubes, however if these are t5 ho and/or have reflectors this may still be high lighting in the early stages, especially if you are not supplementing macro fertilisers. If you feel c02 and distribution are optimised, i would think most of your issues could be attributed to your fertilisers, however you could try further reducing your lighting intensity too.
.....oh, and i think you should start a journal up ;)
Cheerio,
Ady.

Thank you for reply, Crypts coming from my old set up, they aren't emersed form.

Sorry I wrote wrongly about fert, I do use Tropica specialized which contain N and P
Sorry by that.

Yes, I reduced lightening to half because I was hoping to create low maintenance tank with slow growing plants :)
I cant be bother trim the plants every two weeks :)
At the moment I use two t5 39W tubes (865 and 880) with reflector, so do you think it still can be to much?
So should I replace one of them with arcadia grolux for instant?
Or leave it how it is now and remove reflectors only?

Will Elecharis grow with even less light?

mmm, well i got most of that wrong then ;)

with regards the lighting, i wouldnt worry too much about the spectrum, 2 x 39w also doesnt seem excessive on a 250l tank, but you could try going back to basics and removing the reflectors to help ensure good c02 availability.....that way any fert limitations will also be minimised due to slower growth and resultant reduced demands. Algae also indicates a high light issue compared with c02 availability....it sounds stupid, but even your light coloured substrate (of which there is still quite a lot uncovered) may be exaggerating your lighting by reflecting light back into the tank rather than absorbing it like darker ones.....i think im right in saying that....but dont quote me :p
How do you dose your fertilisers, all in one dose or do you split it into daily doses? I always found i had to at least double dose (daily doses) with the old tropica tpn+, so maybe these new ferts are the same and there is still a shortfall with your current set up....although you stated above that there are no particular deficiencies so maybe this is less likely the issue.....its most likely a light and c02 relationship.
I see you have moved away from spraybar configuration, is there a reason for this?
Cheerio,
Ady
