Other then the extra tabs (which i do occasionally add) i have been doing the "oliverira" method for years without knowing it. :) That is exactly how i would prep the soil between scapes. Although it in this case had been dried and stored in the dark before cleaning and reuse. This weeks...

I've not seen the specific filipe method. these have been dried and stored. then before reuse the "fines" extensively rinsed. Then capped with newer soils.

It is trying.... with a single tank you would just restart and hope it goes away but the slog of having it in all the tanks, different ages, does just kick it out of you. Todays water changes on the remaining 5. The two at the end (oldest of the scapes) have run a course of GDA treatment and...

We do have the same "tank on the hill" it's just the run from our shared stop cocks to the hall and my house is different pipes, and their internal pipework is older than mine and not used often. Hence the elevated copper, lead and zinc readings. All due to the corrosion of pipework from the...

I've been in this property for 6 years now and did a good few scapes in the house while finishing the room outside. (note the mini landscaping rock in this may have buffered my kh for me) Happy growth... Even the first 6 months in the room were probably ok.... some interesting growth in...

yeah i went through the stuff on metal toxicity while narrowing down that as an option but as i mentioned the testing of the water for the room actually didn't show the same silly readings from the hall. i've done 2 and 4 of your list :)

From the hall. Now i can actually get my supply tested for free as part of a scottish government scheme to improve private supplies to aim to get a grant to fit an acid neutraliser. But really i don't expect ours to be anywhere as high in copper/lead/zinc as the halls next door in the...

I've actually got some analysis done for the water due to the potential of lead and copper in the supply in the community hall near by. We are on the same bit of the supply. The lab tests there were pretty scary but at the same time really only represented the addition of metals from the...

The ph of 4 ish was recorded on a blackwater breeding project I did for Rocket Panchanx last year. I don't recall any test strip tests showing that low ph in the main room however. I do admit that i wasn't obsessively testing stuff until the last 6 months while trying to get to the bottom of...

Alas i do enjoy Happi's posts but this must have been early on in his scaping.... by page 4 he's recounted (been corrected on APF) the idea that NO3 is converted to NH4 by bacteria that are not present enough in low ph tanks. Thought that sounded a little bit too elegant. Certainly think my low...

Certainly the amount of GDA that occurs is almost directly proportional to the level of fert dosing (ie NO3) but obviously in my case this is also somewhat dictated by the energy and fert needs of each tank.

I think i've skim read this one and chatted to Tom B about it before. This does ring true - ". i also discovered low PH water is Prone to GDA when using EI dosing, why? because when using KNO3, Bacteria have to convert NO3 back to NH4 for the plants, plants are normally covered with Bacteria...

about 6.4 but no natural hardness. i reminerlize with TNC GH booster and seachem alkaline buffer for KH. Aiming for 5 dGH and about 3 dKH currently. Although that was all over the place a few months back.

Indeed. They are mounted deliberately higher and then dialled down. With the PAR meter used to check for dark spots. Thanks man, It is actually only that single tank that is hardscape heavy which also runs pretty low light and lean ferts. The rest of 90 - 100% planted. I've leaned away from...

Thanks man, Alas it now makes me somewhat sad going in there. Hopefully soon i'll perk up a bit. I'm going to shift to emersed growth and riparium set ups for a change. Hopefully the lower energy/plant mass in the water and associated water column dosing will not recreate the same diatom and...

Alas it looked it's best back then and plant health has been declining for the reasons above since that time. In various tanks at certain times.

Thanks replies so far guys, alas i'm not sure any "golden bullet" answers so far. I have kind of gone through everything i can think of in the last year trying to nail this. I'm a little rushed just now for more specific answers but here is a photo of the room last March. Before I filled a...

silicate test for freshwater comes out at low levels i tried using water from my dehumidifier in a tank for a while to see if it would help.... alas no.

generally i've turned most of the kessils down and mounted them high. I've got a PAR meter and the worst tanks are split both high and low end. 35 - 80ish mols. Admittedly there are lots of lights in the same room and there was some differences in the timers on the different wall runs. Amended...

Possibly, but i've also addressed the flow in the lower flow tanks with additional powerheads and pumps. Still diatoms. In one tank they started off on the Bolbitis which was directly in the flow from a 1800 lph filter in a 150L tank! Another thing i'd been chasing around recently is that I...

The gravel vaccing was increased as a response to the diatoms tbh. I instigated some deeper cleans of the older aquasoils too. Which were recommended tbh by experts and i've done with sucess in the past too. Because it's effecting all the tanks to some degree I was trying to cover all room...

Hi man, Long time no speak. :) Don't think the overdosing of Mg would be a problem. I'd agree that it hadn't caused an issue as such as Mg isn't going to hurt the plants/fish etc but I ended up with readings of dGH of 10+ in cases with dKH 0/1.... I did plenty of reading around and chatted to...

Hi Folks, It's taken me a while to come query this online as i've been trying to get to the bottom of it myself for the last year. This post is to tap into anyone's experience of similar or opinions on base causes. As you may notice from my sig and possibly remember me i'm somewhat of an old...

Hi man, Any updates with your journey through this? I'm coming back to the forum to detail my issues with GDA on multiple tanks and found your thread. I'm a bit short of time to fully go into it now but i'm also coming from a spring water remineralised angle. I'd also been massively overdoing...

what is this magic you put before me!!?! are you in league with the moss satan! :)

These are tiny tiny species so cuttings is kind of hard. and manually removing bba etc will probably remove a fair amount of the growth hidden within.

I was actually planning on moving the fish out of the tank it's in anyway now the big tank is up and running so I'll give it a shot. It's been a long while since i've od'ed easy carbo. shall i just run 3.5x until it clears up or a week? It may be impossible to split some of the types as the...

Hey hey, Due to some bad maintenance a while back some rare fissidens types I've been nurturing have ended up with a variety of algae on them. I've only got tiny amounts of each but I really want to dip/treat the whole branch but am very uncertain of which method to use to avoid accidentally...

beyond the water changes mentioned above you could also try a small internal UV filter for the duration of the outbreak. I always keep one handy in the rare circumstance that I get a green water algae issue and don't want to black out the tank. Best Regards, John

lots to cover in this.... i'll chip in with an initial warning to be careful with easy carbo and vallis. this is one of the plants that doesnt react well to liquid carbon. it may have been a combination of maxing out the fert supply when you were neglecting it, lack of overall cleaning, slowing...

interesting read. vitamin s :) i've never heard of anyone using it thou. Does it work on BBA?

i noticed that too. :)

it's a bacterial bloom probably caused by the floss in the reactor since it started when i installed that. it also reduced flow to my filter ALOT. i've switched it out to bioballs now and the filter flow is alot better but i still have the cloudy water. I'm going to try a water change daily for...

Hi, Just seeking a little confirmation on this one. I'm getting cloudy water on my corner tank, a new one for me. Am i correct in saying this is due to too low filtration? I added an external reactor with "floss" media in it which is reducing my filter output quite a bit. I compensated with an...

Hi, After my first year stumbling into planted tanks I learned a bit more about the chemistry of what I was doing and put some requests into my water board for the exact make up of my tap water. Low and behold the low KH GH i knew about was actually compounded by a almost total lack of Mg. I...

Hi George, How about the very rare "my flatmate was left in charge of feeding the fish for two weeks while i was at a music festival in Serbia" algae? :D Best Regards, John

Hi, I had managed to nail all the algae in my main tank http://www.ukaps.org/forum/viewtopic.php?f=35&t=3898&start=20#p52875 except Green Spot on the leaves of my slower growing plants. I knew the phosphates were not the issue as the levels in my tap water are between 5ppm and 9ppm, i was...

this is basically sums it up. blackouts would have worked for me if i had got them right and long enough, by the time i had nailed the params (Nitrates up to a decent level constantly) i had the Erythromycin and used it in combination with the blackout (4 days blackout, 7 days dosing) and have...

tumteetum.... 8) took 4 attempts from different online retailers, eventually got 2 orders through. The supplier was asked to "vaguely" label on one occasion. someone i met in the pub that is, not me, i'd never do anything that dodgy. honest. worked a treat thou. lost one amano thou. best...
