Been working on a little algae issue. First photo is 15th April, second photo 1st May. Not there yet, but I'm pleased with the progress. Thought you might like the dramatic before/after.

Although the tank looks grubby in the first photo it's all algae not detritus. I think the issue was actually the opposite. I was water changing, but feeding very lightly (only four fish) and not dosing. When I tested (only a rough dip stick test) my nitrate was 0.

For reference
15th - Dropped lights from 8hrs to 6hrs, 20% water change, manual algae removal
18th - 20% water change, manual algae removal
23rd - 10% water change, manual algae removal, moved the rock out of the front and pushed the plants back to improve flow there
1st - 20% water change, manual algae removal

+ 2 pumps of tropica specialised (almost) every day.

Anyone else got a good before/after?

Fantastic job @tam !!

Btw. you gotta clean that filter sponge on that PatMini though... :) I clean my PatMinis twice a month. They are there mostly for circulation and mechanical filtration. I have two in each my 150L tanks in addition to two HOB's for bio filtration, which I go much longer in between cleaning. Stable water parameters and cleanliness is the key to an algae free tank.

So awesome to see such as transition, and thanks for sharing!

Cheers,
Michael

Thanks :) The filter sponge is all algae growth, I give it a good rinse out in the bucket at each water change. I'll give it a pluck at the next clean though, see if I can get a bit more off and then scrub the plastic parts so it looks less grungy!

3. Filtration - Aquael mini pat
4. Lighting and duration 15w T8 6hrs
5. Substrate - fine gravel
6. Co2 dosing or Non-dosing - none
7. Fertilizers used & Ratios - 1 pump Tropica Specialised per day
8. Water change regime and type - 20% per week 50/50 rain/hard tap
10. Inhabitants - 4 ember tetras - a few cherry shrimp and a couple of small algae shrimp
