Need help

[Aadam210]

Hi , i’m 15 years old and about a year ago i had to take over the responsibility of a quite large marine tank, i honestly didn’t give it much care for the first year however now i am looking to do it properly. However i have run into many problems and was hoping to find some answers here . The tank is about 1000L and sump about 650L it’s 8ft x 3ft x 2ft . I know a few things however i have a lot to learn

Here are just some of the many questions i have:

There is some kind of SHL computer hooked up to the tank which i don’t really understand but what it does say is my Ph is reading 9.4 . there are currently a few fish in the tank including a skeleton eel and hybrid black tang
Does anyone know why the ph is extremely high?

The tank currently has two reef led 90s but no coral and i’m looking for the best lighting schedule for when i do add coral

Also i have been using an rodi machine which hasn’t been changed in years which i now understand is very dangerous as the tds was at around 11ppm. to change the filters i had to unscrew a few pipes and soak the canisters in hot water as they were hard to get of. after replacing and reassembling the whole thing i am only getting waste water and the di resin canister isn’t filling up.

I am also having a massive hair algae problem and don’t know what to do

The hybrid black tang has been tin the tank for close to 3 years now and nothing has been added to tank in that time so i’m sure there is no icy or velvet or anything like that or i assume the fish would be dead already however it shows some symptoms of it like always seeming agitated and swimming kind of sideways

If anyone has any extra information to give me it is much appreciated

I strongly suggest a mentor for face to face consultations. The internet might but is unlikely to be of much help. Maybe there is a local aquarium or reef club you could join and tap into their expertise.
