nft ukcheese terra aquatica bioponics

This week was a pain in the bum,,, i accidently put liquid oxygen in thinking it was silicon ( also not something i should be using in bioponics) this will teach me not to decant chemicals into smaller bottles, not loads only 10 ml in 70l, and i did an immediate tank change ect...but sadly the damage was done. i got a really frothy tank... looked like capachino, and the roots stopped being white, the ph plummeted, daily going from 6.0, to 5.0... and eventually after 3 days the ph started to rise on its own..... joyfully when the ec lowered i topped it back up to 1.0ec... 😱😭the ph plummeted again, and i knew i had gone to strong with the nutes... so i did a water change brought everything to 0.9 again, and i re added the 7g of trikologic ( should really be added once every 6 weeks) but i felt that a restock of beneficial bacteria would be for the best. i looked back at the ghe bioponics information page and found the following extract "Keep your conductivity under 1.0 and above 0.8" so i set the controller to 0.9 and left it for the night. to start with ph went up, then it went down...so i let it eat out to 0.8 and the ph was still going down... at this point im thinking the ph is going down because the bacteria dont have enough nute... i brought the ec up by hand to 1.0 and the ph rose from 5.4 to 5.8 in about 2 hours. so now i think they want to be on 1.0 ec, i will set the controller to 1.0 and see if the ph continues to rise. so now i know where i have gone wrong... the plants have still grown about 8 inches this week, and consumed over 100 litres of water, so im happy that i havent gone so far wrong its going to be a problem, and im gonna hang on and see what happens in the end. ( sometimes id be tempted to tear everything down and start again, but it does look quite nice so..meh we shall see ! !) many thanks for looking guys and please anyone comment i beg you !! many thanks oldtimer👌
