Still in the land of algae bloom here and after a week of knee jerk adjustments (Extra ferts basically) I've spent some time reflecting and researching...
From what I can tell, as far as algae is concerned, there is no absolute clear consensus on causes or cures but CO2, flow, distribution, nutrients and light can all combine to create success or failure. Now I've been running planted tanks continuously for some 24 years now and if you count my childhood then a fair few more years on top of that however in those 24 years I've only actually started completely anew about ½ a dozen times. Algae hasn't been too great an issue for the most part but my worst breakouts have all been of the blue green variety and mostly down to lack of ferts and or circulation. I've noted a behavioural pattern though that runs something like this....
Yikes I've got algae....I'll try this...
A couple of days later...maybe adjust this..
A couple of days later....oh maybe if I change this..
A couple of days later....oh of course I should do this...
A couple of days later...oh no I probably shouldn't have done that..
A couple of days later...ok, I've got it now, I'll do this..
etc. etc.
Finally, having got totally fed up with fiddling about with parameters, I leave it be for more than a few days and...ta dah...improvements, then gone...
So in the case of this setup I'm thinking along the lines that...algae broke out when I backed off on the recommended ADA Step 1 and Brighty K regime and I moved to weekly water changes even though I had increased fish and food wastes to contend with...
Another thought I have is that it may just be that algae blooms can be a natural part of cycling a new tank and that rather than panicking we should simply ride them out with the minimum of messing. What I can say unequivocally is that historically all the troubles I have with my tanks have been down to either neglect or tweaking...
The shot above is of my tank this evening before cleaning/trimming..there's plenty of new growth in both plants and algae. Last water change and trim was 4 days ago when my new deeper Cal Aqua x2 inflow pipe was installed which improves flow lower in the tank due to it greater depth and all round because of the increased water flow through the additional slots in the tube.
So tonight I rinsed out the filter media with aquarium water and did a 50% water change adding just ADA Step 1 and Brighty K and enough Bicarb to give me KH 5. I've been tempted to switch to another fert regime because ADA seems so overpriced but in a small 60cm tank ADA costs aren't extreme and it is the system that I've been wanting try for years so I'm going to stick with it and order up some Step 2 as I'm easily at the 3 month stage. My drop checker and PH meter all suggest that CO2 is fine and in such an open tank I'm pretty darn sure flow is ok so I'm resolving to ride things out for awhile without meddling.....

Be back next week!
