Well I have bitten the bullet this weekend. I have bought some no-frills topsoil which is currently soaking in a big bucket in the garden, I'll be changing the water every two or three days to leech out as many nutrients as possible before it goes in as the first layer of substrate.
I'm planning on making my smaller Rena 80 litre tank the guinea pig so in 2-3 weeks I will empty it, mix one part soil with 2 parts silica sand and then add a further layer of sand over the top. I will then be checking pH, ammonia, nitrite and nitrates very closely for about two weeks. If all is good there then I will add the rest of the soil (which will have had a couple of weeks extra soaking to the main Juwel tank). I have picked up some dorset pea gravel (3mm) for the top layer in the Juwel as suggested in Diana Walstad's very thorough book. It arrived on Friday morning and I was engrossed in it for a couple of hours, looking mainly at the substrate section. I'll look at it in more detail as the soil is soaking but I think I get the basics.
In the meantime, I have had a rescape of my tank. I've been suffering from an algae problem, the tank is fairly recently cycled, I've gone through the brown diatom phase and, by looking at Jamesc's website, I think I'm suffering from an outbreak of black brush algae. The algae has coated the rock background but mainly at the height of the filter outlet (fast flow area). It is also all over the leaves of my slow growing plants, the glass at the front of the tank, the sand substrate and caught in the Cabomba leaves as it has been blown around the tank.
I bought a fine mesh net to catch as much as possible, scrubbed the rock background and syphoned the substrate a bit too, I've caught most of it but I guess it will be back with a vengeance soon. I have got rid of my Mayacca as it was completely black and my swords and crypts from the front, I'll start again with some more of those when the soil substrate is in so the roots have what they need. I've had a fair bit of growth in the tank, despite the lack of CO2, inert substrate and low light level. The Mexican Oak Leaf has shot up as well as the Elodea and also the Hygro. If the growth rate continues I'll probably be about ready for some pruning at the same time as changing the substrate (4-5 weeks)
Does anybody have any advice on the algae, do you think it sounds like BBA? It looks black in the tank but then slimey green, slight blue tinge out of the tank (doesn't smell though so I don't think it is BGA) it is slimey but does wipe off pretty easily from leaves with fingertips or tapping the net on the stem. If so, what is the best way to eliminate it? I’m kind of fire fighting at the moment, and expect it back soon! My light levels are low (1.25WPG) 12 hours light with a 2 hour siesta. Loads of algae busting plants plus hornwort floating around. I could wait it out and manually remove what I can if things are likely to improve of their own accord. Otherwise what about dosing Flourish Excel (double doses?) If I did this, perhaps 2 sevenths of the recommended weekly dose per day (if you follow!) would I need to do big water changes or not and would my fish be alright? This does not appeal to me. If it is down to uneven CO2 levels then it must be due to water changes as that is how my tank acquires its CO2. As my nitrates are being consumed by my plants, I plan no water changes over the next month or so, so maybe it will clear up.
Any advice here would be most welcome. I suppose the last resort would be a 3-4 day black out with no light at all. Would this do the job for sure?
The plants are being left to do their own thing for the next month or so and I’ll just monitor and act on the algae.
A quick up to date picture of the tank this evening after the rescape and before the anticipated algae return!
