Two weeks in and I think the tanks are back on an even keel.
The first port of call was lowering the the light intensity by 10%, then my main focus has been trying to keep things stable, water changes have been more frequent but at smaller volumes. The first week following the bba outbreak involved daily 15 ~ 20% changes for a week and a 30% change at the weekend. The second week I was changing 10 ~ 15% every other day followed by another 30% change yesterday. I've also been doing weekly filter cleans. I'll probably continue with 2x 15% and 1x 30% for a few more weeks and see how I get on.
Any badly effected leaves were removed and the remaining lesser infested ones got spot dosed with excel 6ml daily for the first week and every other day for the last week. The plan is to reduce this to once or twice a week and then hopefully stop it altogether.
Fertiliser wise the main changes have been ditching the urea and increasing the Po4. K, No3 and Mg have increased slightly and Fe reduced slightly.
New dosing levels are:
Added with the weekly water change 2.27ppm Ca & 1.85ppm Mg.
Then via macro - micro dosing p/w:
No3 11.6 ppm
Po4 2.91 ppm
K 8.52 ppm
Mg 0.89 ppm
Fe 0.31 ppm from csm+b
Fe 0.11 ppm Dtpa.
Still have a small amount of bba but its definitely reducing. Gsa is still present on some older leaves, new growth appears free of it. The plants in general are doing well and the new growth is no longer stunted or twisted.
I've no idea what caused these issues or what part of my new regime is curing it. I can only think stability is helping out to some extent.
Still struggling to take half decent fts pics but here they are.
Last week I added 4 more horned nerite snails and 3 amano shrimp to each tank. Also spotted a couple more black otocinclus at aqualife in Leyland. I'd originally thought these were Otothyropsis Piribebuy but I'm now leaning towards Hisonotus notatus any thoughts appreciated @Conort2
Not sure if the snails will eat the remnants of bba...
Cryptocoryne spiralis red lost 2 leaves to melt when it first went in the tank but is now putting out new leaves, not sure if the green vein is normal in this plant but it looks stunning in the flesh. Photo doesn't do it justice.
I should have done a before and after shot of the echinodorus, 2 weeks ago the edges of these leaves were covered in bba.
Got a big bag of leaves and alder cones from @dw1305 last week and added a small amount to each tank yesterday, I usually scald any leaves that get added to the tank to stop them floating and getting sucked into the wave maker/gyre.
Was mightily impressed with the effect that 3 alder cones and 5 Hornbeam leaves (I think) made on the jug water after 40 mins. By contrast half a dozen catappa leaves would only add a slight tint to this water.
Lastly and sadly it's not all good news. My dwarf snowball plec that had been struggling for some time died 2 weeks ago. I think their timid nature probably makes them less than suited to active fish tanks and maybe that's the reason it perished. I do however suspect my tinkering with this tank has in some way contributed to its demise and that's something that sits heavy on my conscience.
