please help me, i have recently started in planted tanks from keeping plants in a tank with tropicals
I have generally had good success with my plants in that they dont die - but they are just so darn slow! a while back i had great revelations when i started adding CO2 (DIY) and the plants took off little bubbles everywhere
Now its all stopped and I have decided its time to start with fert. Was only using 'florena' and florinette A a combination of tablets and juice - which i have found to be close to tap water. I have managed to source KNO3 and others from hydroponics stores and its time to go for it i guess
90L (23 gal) AGA
its a high top - 3ft x 2ft x 1ft
Substrate is Ferral (a red iron trace stuff) and Terralit topped with black gravel
I have undergravel heating
1000lph canister and 7w UV
Lighting is 3 x 3ft flouro tubes 30w each
2x 10000K 1'plant grow'
ph - 6.6
CO2 - DIY tests at >25ppm with sera colour indicator
7 rainbows, 3 corys, 5rummynose, 3ottos, 1 whiptail and 2 peppermint BN.
2 large swords, 2aponogon, several crypts (wentii and other) large red lotus, anubius nanna, and bunch of "babys tears'
yesterday i dosed nitrates to 20ppm, K -15ppm and 1-2 ppm phosphates - i also gave a slightly larger dose of my florena
still no bubbles
do i have enough light? should i also have dosed MgSO4? Is it iron?
what am i missing ?
