Alright, this may end up long but I'm going to breakdown my entire build for you the best I can to hopefully answer some of your questions and any more that you might come up with! Bare with me
Luckily I haven't seen any type of algae blooms since my tank has been running, besides the tiny amount on the far back of the glass that gives it that slight hazy appearance. Nothing changed even after I added the Finnex. Keep in mind my tank is about 23'' tall and the light about, so your Finnex may be having more of an affect on your 20 gallon long than mine may show. I don't know if my Finnex puts out enough for me to successfully grow low carpet type plants with my tank being quite taller, but I'm going to trial and error it and see what happens.
Not sure what you have as far as a clean up crew goes, but I have quite a bit of pest snails, 4
assassin snails added recently to keep them in check, an albino brittlenose pleco who's always at work, and my 6-7 inch
rainbow shark is always sweeping every inch of the tank. On top of that all my
corys keep bottom build up to a bare minimum.
I do not have an advanced Co2 system or anything, nor do I know all that much about it, but this tank is more or less a trial and error build as it is my first larger sized planted tank. I am just running the ISTA water plant 45g cartridge system that I picked up at petco to experiment with. I've stopped dosing liquid Co2 to see how it works out alone at about a bubble per second. Since I've stopped dosing liquid Co2, I've also changed up my light schedule a little bit to see if I can get some noticeable change in my plants.
I've been turning my Finnex on to the 9am setting at around 11am when I wake up, and turn on the Co2 at about noon as well as switching to max setting. Around 10:30pm when I get home, I turn off my Co2, and switch the lights to the 6pm setting for about an hour. Then around 11:30pm-midnight I switch to the 9pm or midnight setting, which is on for about an hour give or take before I turn off the light entirely. Wake up, repeat the process. Pretty much worked around my work schedule lol
I have about an inch of
fluorite underneath an inch and a half or so of
black sand.
I'm currently using the apI root tabs, but I think they should be on their last limb.
My
flourish tabs, seachem enhancer, and fundamental packs are expected to arrive on Monday so those will be factored in next week. I am currently dosing flourish 1-2 times a week though, as well as dosing Tetra EasyBalance Plus once a week as well.
So far, all my fish are alive(lol!) and very active, and my plants are all brightening up very well so I want to think there has been improvement!
Here's some specs for ya:
60 gallon tank
48'' Finnex planted+ 24/7 of course
750 gph flow rate
78 deg
2
water changes a week
(10-20% in the middle of the week, 30-40% on sundays)
I'm going to check my water levels later today so I'll post those up for you as well!
As of last week:
7.6-7.8
PH
Ammonia 0-.25ppm
Nitrite 0ppm
Nitrate around 40ppm
pH may have dropped a little bit with the add on of pressurized Co2 and a few more pieces of
driftwood so like I said, I'll post up fresh numbers at some point soon!
I'm going to need to do some re-homing eventually, as well as upping some schools, but here's my stock list as of now
4 Angels
1 Gold
Gourami
1
Paradise Gourami
1 Rainbow Shark
1 Albino
BN Pleco
2 Red lamp tetras
6 gold
pristella tetras
6 rosy fin tetras
2 false JulI Corys
3 large Emerald corys
3 Albino corys
4 Assassin snails
xx pest snails
Here's the tank on max setting as it stands. Did a little re-scaping the other day with a few added ferns to the back right corner. Excuse my glass being a little dirty from spilling water down the front!
