I have been battling with algae/ growth issues for a long time now and decided I needed some expert help.
Tank was set up in August 2015
ADA Mini M (5.4 Gal) with glass lid
ADA Amazonia powder soil
GLA Paintball co2 with do aqua diffuser (drop checker reads a light green)
ADA Superjet 150 filter 80% Biorio 20% bamboo charcoal
-I recently added an eheim 2211 inline with the superjet
Two biggish pieces of seriyu stone and a few smaller pieces
HC, DHG, Riccia, Glosso
12 boraras fed 1 pinch of food/day
2 Amano shrimp (they tend to be suicidal)
Green Brighty Step 2 1-2 pumps/day 5 days/week
Brighty K 1-2 pumps/day 5 days/week
5 Osmocote root plus tabs (put in 1month ago)
Green gain after trim (2/month)
50%water change 1/week
PH without CO2 before water change 7.2 caused by stones/soil?
dKH Before water change 5-7
Low Nitrate/ite and ammonia (all close to 0ppm)
Water change with NYC water (very low kh and gh) w/10 drops aqueon water conditioner sits for 15mins before change
I've always had BGA problems (especially in the corners of the tank) but got them under control about 3 months ago but then my DHG was growing poorly and had spongy brown slime at their bases. I added Osmocote tabs (5) interspersed throughout the tank and started brighty lights and eca to bring the DHG back (low iron was suggested as the cause). BGA outbreak happened almost overnight so I stopped the brighty lights and the eca which made it slightly better. Then I added the eheim 2211 inline (2 weeks ago) hoping it would help with current as that was also suggested as a potential cause of the BGA. Now its still pretty bad and my HC carpet is looking unhappy. DHG is growing a bit better but now looks a bit pale and my glosso which is usually strong looks weak too. Also getting some minor hair algae for the first time since month 1 of the tank.
Thanks for all the help!
